# AntrumX vs Aircuity Comparison

![](https://antrum.com/hubfs/raw_assets/public/sr-child-theme-antrum/images/tab-notch-thingy.svg)

**The video shows comparable components, with circles identifying the equivalent component on each platform.**

The opening audio is an Aircuity vacuum pump at an installed system, recorded by Antrum in January 2024 while operating normally. Audio levels were not adjusted. The AntrumX panel that follows makes no comparable sound: its venturi has no motor and no moving parts.

 This page compares AntrumX and Aircuity component by component for a representative 32-zone centralized DCV monitoring deployment. Zone-level pickup tubing is included where it differs between platforms; connections common to both systems are noted as such. Aircuity is currently rebranding as Thrive Buildings.

 Prepared by Antrum, the manufacturer of AntrumX, from Aircuity's published documentation (accessed October 20, 2026) and a modeled 32-zone configuration. Configurations, options, and contract terms vary. See [Sources](https://antrum.com/compare/antrum-vs-aircuity#sources). Spot an error? [Let us know](https://antrum.com/contact?hsLang=en) and we will review it promptly. 

About this comparison

This comparison was prepared by Antrum, Inc., the manufacturer of AntrumX, and reflects Antrum's analysis. Information about Aircuity products and services is based on Aircuity's publicly available product data sheets and service documentation, downloaded from aircuity.com on October 20, 2026 (see Sources), and on Antrum's observations of installed systems. Component counts reflect a representative 32-zone deployment as modeled by Antrum. Actual requirements for either system may vary with design, site conditions, product options, and contract terms. Aircuity may change its products, software, and service offerings at any time, and readers should confirm current details directly with each manufacturer. Third-party test results apply only to the specific samples and conditions described in the referenced report and are not a representation about any product's performance in a particular installation.

Aircuity and Thrive Buildings are trademarks of their respective owners. Antrum is not affiliated with, endorsed by, or sponsored by Aircuity or Thrive Buildings. If you believe any information on this page is inaccurate, [contact us](https://antrum.com/contact?hsLang=en) and we will review it promptly and correct it where appropriate.

## Infrastructure at 32 zones

 A 32-zone deployment is the capacity of a single AntrumX panel. The comparable Aircuity configuration is one SST750 Sensor Suite with two limbs of four Air Data Routers (ADRs), each ADR serving four zones.[5](https://antrum.com/compare/antrum-vs-aircuity#src-5),[6](https://antrum.com/compare/antrum-vs-aircuity#src-6) 

How we counted

**Aircuity:** one SST750 Sensor Suite, eight ADR604 Air Data Routers, one Information Management System (IMS), two transformers (one for the SST, one for the ADR network[4](https://antrum.com/compare/antrum-vs-aircuity#src-4)), and the optional backup vacuum pump.[2](https://antrum.com/compare/antrum-vs-aircuity#src-2) **AntrumX:** one 32-zone panel and one Air Accelerator venturi, which is not powered.

**Powered components** are devices that require electrical power. **Line-voltage connections** are field-wired 120 Vac connections. **Low-voltage terminations** are 24 Vac power connections made at a component. **Tubing terminations** are field-made connections in the sample path between the zones and the sensors.

Items common to both systems at the zone level are counted the same way for both.

### Powered components and electrical connections

| Component | AntrumX | Aircuity |
| --- | --- | --- |
| Monitoring panel / SST | 1 | 1 |
| Information Management System (IMS)[3](https://antrum.com/compare/antrum-vs-aircuity#src-3) | 0 | 1 |
| Transformers[4](https://antrum.com/compare/antrum-vs-aircuity#src-4) | 0 | 2 |
| Air Data Routers[5](https://antrum.com/compare/antrum-vs-aircuity#src-5) | 0 | 8 |
| Vacuum pumps, with optional backup[2](https://antrum.com/compare/antrum-vs-aircuity#src-2) | 0 | 2 |
| Total powered components | 1 | 14 |
| Line-voltage (120 Vac) field connections[2](https://antrum.com/compare/antrum-vs-aircuity#src-2),[4](https://antrum.com/compare/antrum-vs-aircuity#src-4) | 1 | 3 |
| Low-voltage (24 Vac) power terminations[4](https://antrum.com/compare/antrum-vs-aircuity#src-4),[5](https://antrum.com/compare/antrum-vs-aircuity#src-5) | 0 | 9 |
| Powered components typically outside the mechanical room | 0 | 8 |

Counts reflect the 32-zone configuration described above. The IMS plugs into a standard outlet and is not counted as a field connection.

 AntrumX has one electrical connection: 120 Vac to the panel. There are no powered components to locate, mount, or wire anywhere else in the building. In the Aircuity system, the transformers and the vacuum pump bracket require line-voltage connections, and 24 Vac power runs through the OSC backbone cable to the SST and each ADR, which are typically located near the zones they serve.[2](https://antrum.com/compare/antrum-vs-aircuity#src-2),[4](https://antrum.com/compare/antrum-vs-aircuity#src-4),[7](https://antrum.com/compare/antrum-vs-aircuity#src-7)

### Tubing terminations: zone to sensors

 Both systems require two tubing terminations per zone run: one at the room and one at the collection point. That is 64 terminations for 32 zones on both platforms, identical at the zone level.

 The difference is what happens between the collection points and the sensors. AntrumX zone tubing routes directly to the panel. Aircuity ADRs connect to the SST along an OSC Structured Cable backbone arranged in limbs of up to 500 feet.[6](https://antrum.com/compare/antrum-vs-aircuity#src-6),[7](https://antrum.com/compare/antrum-vs-aircuity#src-7) Those backbone segments require field-made terminations that have no equivalent in AntrumX.

| Termination type | AntrumX | Aircuity |
| --- | --- | --- |
| Zone pickup terminations (32 zones x 2) | 64 | 64 |
| Backbone between ADRs (3 per limb x 2 limbs x 2 ends) | 0 | 12 |
| Backbone from each limb to the SST (2 limbs x 2 ends) | 0 | 4 |
| Total tubing terminations | 64 | 80 |

 Aircuity requires 16 additional field-made tubing terminations for the same 32 zones. They carry no zone data of their own, and each one also terminates the OSC cable's power conductors (18 AWG, three wire) and data conductors (22 AWG shielded pair with drain).[7](https://antrum.com/compare/antrum-vs-aircuity#src-7)

## Air Accelerator: venturi vs. vacuum pump

 Both systems require a mechanism to draw air samples through the tubing network to the central sensor location. The approach each platform takes determines maintenance requirements and long-term operating cost.

AntrumX: venturi

 AntrumX uses a purpose-designed venturi connected to header ductwork. Air is drawn through the sampling network using building static pressure. No motor, no moving parts, nothing to wear out or replace.

 Flow varies with building static pressure. Installation location is selected to minimize exposure to excessive static pressure swings. For performance data across static pressure ranges, see the [Air Accelerator cutsheet](https://antrum.com/resources/specify?hsLang=en#components).

Aircuity: vacuum pump

 Aircuity uses an oil-less rocking-piston vacuum pump that provides continuous vacuum to the SST. It is offered as a single pump or with a backup pump that switches in automatically on a sustained loss of vacuum.[2](https://antrum.com/compare/antrum-vs-aircuity#src-2)

 Vacuum pumps contain moving parts. Aircuity lists them among the consumable components covered under its service agreement.[1](https://antrum.com/compare/antrum-vs-aircuity#src-1)

## Air sampling tubing

 Both AntrumX and Aircuity route air samples through tubing from each zone to the central sensor location. The material of that tubing, and whether it is consistent throughout the entire sample path, matters in laboratory and life science environments where acids, solvents, and other chemical vapors are present.

### AntrumX: carbon-impregnated FEP (CFEP) throughout

 AntrumX specifies carbon-impregnated Fluorinated Ethylene Propylene (CFEP) tubing for the entire air sample path, from the zone faceplate through to the sensor connection inside the panel. There is no change in tubing material at any point in the path. CFEP is chemically inert, meaning it does not react with or absorb chemical vapors passing through it. More information is available in the [AntrumX component specifications](https://antrum.com/resources/specify?hsLang=en#components).

 Because AntrumX has no remotely mounted components, there are no electrical conductors in the tubing runs. The tubing carries air samples only.

### Aircuity: MicroDuct tubing

 Aircuity's OSC100 Structured Cable, used between the SST and ADRs as the system backbone, contains a MicroDuct inner tube made of a fluoropolymer resin and carbon nanotube blend, together with low-voltage power and data conductors inside an outer sheath. The MD100 MicroDuct Tubing uses the same inner tube without conductors and is used for zone-to-ADR runs; OSC100 can also be used for those runs where room temperature sensing is needed.[7](https://antrum.com/compare/antrum-vs-aircuity#src-7),[8](https://antrum.com/compare/antrum-vs-aircuity#src-8)

 Neither tubing data sheet covers the tubing inside the SST that connects air samples to each sensor, and we could not find a published material specification for that segment of the sample path.[6](https://antrum.com/compare/antrum-vs-aircuity#src-6),[7](https://antrum.com/compare/antrum-vs-aircuity#src-7),[8](https://antrum.com/compare/antrum-vs-aircuity#src-8)

Third-party materials testing (commissioned by Antrum)

 An ISO 9001:2015 certified materials laboratory tested three samples in July 2026: clear panel-internal tubing (Sample A) and green field sampling tubing (Sample B), both removed from another manufacturer's installed centralized DCV system after about three years in service, and new Antrum CFEP tubing (Sample C).[9](https://antrum.com/compare/antrum-vs-aircuity#src-9)

 Under the hydrochloric acid and nitric acid exposures tested, Samples A and B both exhibited measurable physical changes, including discoloration, surface roughening, and in one case reduced flexibility and vitrification. Sample C showed no change in color, flexibility, or surface smoothness under either acid type or at either exposure duration tested.

 The full test report is available for download: [Tubing Test Report](https://antrum.com/resources/specify?hsLang=en#components)

 AntrumX uses CFEP throughout the entire sample path with no change in material and no conductors in the tubing. The tubing specification is published and consistent end to end. When you specify AntrumX, you know exactly what your air samples are traveling through from zone to sensor.

## Valve integrity: continuous verification

 A solenoid valve that fails open is a silent data integrity problem in any centralized air sampling system. When a valve fails open, that zone's tubing remains connected to the sensor as the system advances to the next zone. Every subsequent reading picks up residual air from the failed zone, compromising IAQ data for every room sampled by that sensor, not just the one with the failed valve.

AntrumX

 After each zone sample, all valves close. The sensors verify that airflow has ceased completely. Zero detected airflow confirms two things simultaneously: the sample path is clear and no valve has failed open. The next zone valve opens only after this is confirmed. The purge volume is fixed and contained entirely within the panel.

Zero-airflow check: every 60 seconds on each of two 16-zone manifolds, verifying two valves per minute across the panel

Per-valve verification: once per 16-minute sampling cycle, about 90 times per day

Aircuity

 The solenoid valves are inside the ADRs, four per ADR, one per zone.[5](https://antrum.com/compare/antrum-vs-aircuity#src-5) In Aircuity's published remote monitoring, ADRs are listed only for communication loss (no data for 24 hours). The component failures listed are sensors and vacuum pumps.[1](https://antrum.com/compare/antrum-vs-aircuity#src-1)

ADR monitoring: communication loss only; valve failure is not a listed condition[1](https://antrum.com/compare/antrum-vs-aircuity#src-1)

 AntrumX checks for a failed-open valve every 60 seconds as part of normal operation, so a valve that fails open is detected within one sample interval.

## Data platform: local vs. cloud

AntrumX: Embedded SkySpark

 Installed directly on the gateway hardware inside the panel. All data is stored and processed on site. The platform operates fully without an internet connection. Data is accessible remotely via LAN or if the customer decides to connect the gateway to the internet. If internet connectivity is lost, the system continues operating and logging without interruption.

Aircuity: on-site IMS with cloud platform

 Data from the SST and ADRs is collected on an on-site Information Management System (IMS) and uploaded to MyAircuity.com, which requires outbound internet access.[3](https://antrum.com/compare/antrum-vs-aircuity#src-3) Aircuity's remote monitoring, dashboards, and analytics are provided for cloud-connected systems.[1](https://antrum.com/compare/antrum-vs-aircuity#src-1)

 For facilities with data governance requirements, cybersecurity policies that restrict cloud connectivity, or operational resilience requirements, common in life science, government, defense-adjacent research, and healthcare environments, AntrumX's local-first architecture is a meaningful distinction.

## Controls integration

AntrumX

 The AQMS calculates a demand-controlled ventilation (DCV) value that can be scaled into multiple unit types and passed to the room controller over BACnet IP or MS/TP. The DCV signal is configurable per space. For full BACnet point documentation, see the [Lab Controls cutsheet](https://antrum.com/resources/specify?hsLang=en#integration).

 AntrumX also supports direct integrations with multiple laboratory air valve manufacturers. Integration instructions are available at [antrum.com/resources/specify](https://antrum.com/resources/specify?hsLang=en#integration).

Aircuity

 Aircuity integrates with the building automation system through BACnet on the IMS.[3](https://antrum.com/compare/antrum-vs-aircuity#src-3) An optional ADR version, the ADR604-IO, adds eight hardwired inputs and eight outputs at the ADR.[5](https://antrum.com/compare/antrum-vs-aircuity#src-5)

## Sensor calibration

 Both AntrumX and Aircuity use NIST-traceable sensor calibration,[1](https://antrum.com/compare/antrum-vs-aircuity#src-1) and both platforms centralize all sensors at a single location, the architecturally correct approach for DCV in critical environments.

 Where the platforms differ is in calibration cost, who can perform it, and what the calibration event triggers.

AntrumX calibration

 All sensors in Sensor Packs inside the panel, one per 16-zone manifold  
 No tools required  
 Completed in under 60 seconds  
 Can be performed by any facilities staff member  
Fixed cost: $1,444 USD per calibration event  
 Service contract available but never required

What the calibration event triggers:

 Calibration certificate stored on the Sensor Pack, accessible in AntrumEYE  
 Software updates delivered automatically, with no downtime or manual intervention  
 Warranty extended until the next calibration event  
 Service life countdown timer resets

Aircuity calibration

 Recalibrated sensors installed by the Aircuity representative  
 Once a year or bi-annually, depending on application and system configuration[1](https://antrum.com/compare/antrum-vs-aircuity#src-1)  
 Delivered through Aircuity's Calibration Laboratory and Assurance Services program[1](https://antrum.com/compare/antrum-vs-aircuity#src-1),[10](https://antrum.com/compare/antrum-vs-aircuity#src-10)  
 Scheduling and cost governed by the service agreement

### Sensor lifetime tracking and error-proofing

 Sensors have a published service lifetime. AntrumX Sensor Packs returned from the field for re-calibration are evaluated against that lifetime. Each Sensor Pack carries internal storage tracking calibration history and remaining lifetime, integrated directly into Antrum's calibration software.

 If a returned Sensor Pack's remaining lifetime is shorter than one calibration interval, the calibration process is blocked at the hardware level. Antrum does not deploy a Sensor Pack whose remaining lifetime is less than one full calibration interval. The system cannot be misconfigured to do so.

## Calibration expiration: system behavior

 What happens when a calibration interval is exceeded determines whether overdue calibration becomes an operational event or goes unnoticed.

AntrumX: defined safe ventilation

 Upon expiration of a Sensor Pack calibration, the DCV value is automatically set to a configured maximum, triggering the room controller to ventilate at the highest programmed rate. The Sensor Pack stops reporting variable data and the BACnet point carries an event message identifying it as expired.

 For full BACnet point behavior on expiration, see the [BACnet Points List cutsheet](https://antrum.com/resources/specify?hsLang=en#integration).

 AntrumX expiration is an operational event: the system signals for action and the room is ventilated at a defined safe rate until the Sensor Pack is replaced.

## Frequently asked questions

What tubing material does AntrumX use, and does it matter in a lab environment?

AntrumX uses carbon-impregnated FEP (CFEP), a chemically inert fluoropolymer, throughout the entire air sample path from zone entry to the sensor connection. The material does not change at any point, and there are no electrical conductors in the tubing. In laboratory and life science environments where acids, solvents, and chemical vapors are present, tubing material matters: a non-inert tube can absorb or react with vapors passing through it, which can affect air quality readings. In Antrum-commissioned third-party acid resistance testing, panel-internal and field sampling tubing removed from another manufacturer's installed system after about three years in service showed measurable physical changes under hydrochloric acid and nitric acid exposure. New Antrum CFEP showed no change under either acid type. The full test report is available at [Tubing Test Report](https://antrum.com/resources/specify?hsLang=en#components).

What is the difference between AntrumX and Aircuity?

Both are centralized DCV monitoring platforms that route air samples from individual rooms via tubing to a single sensor location. AntrumX consolidates all infrastructure at one panel with one electrical connection and no powered components outside the mechanical room. In the 32-zone configuration on this page, Aircuity uses 14 powered components, 8 of which (the ADRs) are typically located outside the mechanical room, and its OSC backbone adds 16 tubing terminations beyond those required at the zones.

How does AntrumX draw air samples without a pump?

AntrumX uses a purpose-designed venturi connected to header ductwork. Building static pressure draws air through the sampling network: no motor, no moving parts, nothing to wear out or replace. For performance data across static pressure ranges, see the [Air Accelerator cutsheet](https://antrum.com/resources/specify?hsLang=en#components).

How often does AntrumX verify its solenoid valves?

Every 60 seconds, as part of normal operation. A 32-zone AntrumX panel has two 16-zone manifolds, each with its own Sensor Pack, sampling in parallel. After each zone sample, all valves on that manifold close and the system confirms zero airflow before advancing, so the panel verifies two valves every minute. Each valve is verified once per 16-minute sampling cycle, about 90 times per day.

Does Aircuity's remote monitoring report valve failures?

Aircuity's solenoid valves are located inside its Air Data Routers (ADRs). In Aircuity's published remote monitoring, described in its Assurance Services Commitment (03/2024), ADRs are listed only for communication loss, meaning no data for 24 hours. The component failures listed are sensors that are flatlined or out of specification and vacuum pumps not providing the required vacuum. Solenoid valve failure is not among the listed conditions, so an ADR that is still communicating would not trigger a listed alert because of a failed valve.

What happens if a solenoid valve fails open in a centralized DCV system?

The failed zone's tubing stays connected to the sensor while the system advances, contaminating every subsequent reading. IAQ data becomes unreliable for every room sampled by that sensor, not just the failed zone. AntrumX detects this within one 60-second sample interval.

What happens when an AntrumX Sensor Pack calibration expires?

The DCV value is automatically set to a configured maximum and the Sensor Pack stops reporting variable data. The BACnet point carries an event message identifying the Sensor Pack as expired. The room is ventilated at the highest programmed rate until the Sensor Pack is replaced. Full BACnet point behavior is documented in the [BACnet Points List cutsheet](https://antrum.com/resources/specify?hsLang=en#integration).

Does AntrumX require cloud connectivity?

No. AntrumX runs on Embedded SkySpark installed on the gateway hardware inside the panel. The platform operates fully on site without an internet connection. Data is accessible remotely via LAN or if the customer decides to connect the gateway to the internet.

What does AntrumX calibration cost?

$1,444 USD. No tools required, under 60 seconds, performable by any facilities staff member. No service contract required. The calibration event also extends the warranty, delivers any pending software updates automatically, and stores the calibration certificate on the Sensor Pack itself.

How is Aircuity calibration delivered?

Through Aircuity's Assurance Services Commitment (03/2024): recalibrated NIST-traceable sensors are installed by the Aircuity representative once a year or bi-annually, depending on the application and system configuration. The agreement's hardware coverage also includes replacement of sensors, SSTs, ADRs, the IMS, and vacuum pumps.

Why does Aircuity require 16 more tubing terminations than AntrumX for the same number of zones?

Aircuity's ADRs connect to the SST along an OSC Structured Cable backbone arranged in limbs. In the 32-zone configuration on this page, the backbone segments between the SST and the ADRs add 16 field-made terminations that carry no zone data, and each also terminates the cable's power and data conductors. AntrumX routes all zone tubing directly to the panel with no intermediate components.

How many field-wired connections does a 32-zone AntrumX system require?

One: a single 120 Vac connection to the monitoring panel. All other infrastructure is contained within the mechanical room with no field-wired connections outside it.
