Zaack IAQ®

Monitor your IAQ : With Zaack QAI® connected station

The Zaack IAQ® station is built to measure Indoor Air Quality. It was designed to be a powerful diagnosis device, pairing precision and exhaustivity to properly identify pollution sources.
Each pollutant has its own dedicated device chosen from the most performant on the market, and calibrated internally specifically for ambient air monitoring to ensure maximum reliability.

ZAACK IAQ® is a connected monitoring station: it sends pollutant concentration measurements to a secure cloud platform. Pollutant concentrations are consultable in real-time with our web or mobile apps. Several other services such as counselling and alerts can also be provided.

The Citeair european air quality index was elaborated to represent outdoor air quality in cities. It includes pollutant concentration for 3 main pollutants (NO2, O3, PM10) and can include 3 secondary pollutants (CO, SO2, PM2.5).
Zaack IAQ® measures all 3 main pollutants as well as 2 secondary pollutants, PM2.5 and CO (or SO2 in option instead).
Also measures fine particles PM1 that aren’t officially regulated yet as well as Total VOCs, one of the major indoor pollutants (from cooking, household products, furniture, etc.).

Beyond sanitary issues, indoor environment is also essential for the well-being of occupants.
Environmental parameters such as temperature, relative humidity, atmospheric pressure, sound, luminosity or CO2 concentration can all affect well-being and productivity.

Zaack IAQ measures the more elusive comfort parameters such as CO2 concentration (representative of confinement and air renewal), temperature, relative humidity and pressure that can help you optimize your comfort.

All components come from our close European neighbours and assembly is integrally made in France.
Zaack IAQ® is available for leasing or buying. Even after a few years of use, it can easily be reconditioned through changes to housing or sensors parts and reused. The end of life of the different parts of Zaack IAQ are integrally managed by Zaack and its partners, to ensure recycling and proper management of non-recyclable parts.

Zaack Driver of the quality of your indoor air


Zaack IAQ® measures in real-time 11 of the most common indoor pollutants. Each pollutant has its own dedicated sensor to ensure specific and accurate air quality data :

  • Comfort parameters: temperature, relative humidity, atmospheric pressure
  • Chemical pollutants: CO2 (carbon dioxide), NO2 (nitrogen dioxide), O3 (ozone), CO (carbon monoxide), TVOCs (Total Volatile Organic Compounds)
  • Fine particles: PM1 / PM2.5 / PM10
  • Possible on-demand measures: H2S (hydrogen sulfide), SO2 (Sulphur dioxide), CH4 (Methane and Hydrocarbon)

Reliable measurement are ensured by comparison to refernce analyzers prior to every deployment of our devices.
A validation certificate is also established (currently only on demand).

Zaack IAQ® is a connected monitoring station: every thirty seconds, data logs are sent to the cloud through a secure connection.

Data are available for visualization through our mobile and web apps.

We manage the entire platform

Zaack connected solutions ensure continuous monitoring of indoor air quality. Connected to the Internet, Wifi network (4G) or LORA, the collected data is transmitted via a secure connection to our servers.
Owned by the client, the data is stored in a secure data center. The data history can be viewed in real time via our web and mobile applications.

Based on deep learning, the more data we collect, the more we know the specifics of your building. Coupled with open data on outdoor air quality, our artificial intelligence ensures continuous monitoring of the parameters of your indoor air quality:
Predictive maintenance, new air supply, filter change…

Zaack DUST®

Real-time monitoring of dust deposition in ventilation networks: the connected access door Zaack DUST®

Zaack DUST® is a device that can estimate the amount of dust deposited in air ducts.

Today, maintenance is scheduled with either of two strategies:

Curative maintenance : with the identification of an issue such as degradation in functionality of the duct network, often too late and causing both energy loss (leading to overconsumption) and degraded indoor air quality (IAQ)

Predictive maintenance : which is very likely to be either unnecessary or too late with regards to official guidelines and standards for ventilation network maintenance (NF EN 15780)

Our innovative product provides real-time monitoring of dust deposition inside the ducts and is a powerful tool to identify when maintenance is needed and schedule cleaning prestation ahead of time. This leads to organisational benefits, energy savings as well as improved IAQ.

Optical measurements allows precise evaluation of the evolution of dust deposits in air ducts

No need to have specialised personnel do on-site measurement to evaluate the cleanliness of the air network.

Timely cleaning of air ventilation ducts helps reduce dust accumulation on filters and therefore reduces energy loss in the system.

Following NF EN15780 Standard can help lower air quality issues that can spread through air ducts, such as Particulate Matters or bio-pollutants (pollens, allergens, mold, bacteria and viruses), ensuring well-being and limited health impacts.

An innovative product to meet a Standard

Based on the various national legislations and the recommendations of European organizations, it determines the guidelines for the realization of an adequate maintenance of your ventilation system.

Zaack DUST®:
Pilot of your Aeraulic Installations


Zaack DUST® sensors can be installed on all types of existing networks: blowing, recovery or extraction. It is very strongly recommended to carry out a dusting of the networks at the time of installation.

At the installation, the technicians systematically take a sample of dust in a sheath to calibrate the sensors to ensure the reliability of the measurement. This sampling also makes it possible to judge the quality of the cleaning service carried out before installation.

Thanks to the implementation of a LoRaWAN network gateway,data is retrieved once a week and transmitted over a secure connection to the cloud.

The consultation of data in real time and theexport are done thanks to access to our Zaack DUST application®.

Our application is configured with the alert thresholds recommended by NF EN 15 780. A weekly report is sent to you by email to notify you when the sensors are either at 80% of the alert threshold or exceeding thresholds on your installations.

Zaack DUST®:
Better control of your Facilities

Using Zaack DUST® allows you to implement predictive maintenance on your installations to:

  • Better control andreduction of maintenance costs (cleaning of ducts and diffusers, change of filters, maintenance of air handling plants or fans)
  • Ensure the comfort and health of occupants
  • Energy saving (less load losses on ventilation networks)
  • Be alerted at the right time to trigger a curative intervention (NF EN 15780)

Zaack CR®

Real-time monitoring of fine Particulate Matter in clean rooms

Zaack CR® is a device that can monitor in real-time the particle counts in clean room environments (clean rooms, operating theatre, production chains for pharmaceutics or microelectronics, etc.)

The device allows for remote control of the airborne particle concentration (fine particle counts in pcs/m3) in your clean environments without needing on-site operators. Real-time particle counts are collected, and an alert system paired to your Building Management System (BMS) allows for fast reaction in case an issue arise.

In accordance with clean room standards, our monitoring system gives an estimation of the airborne particle count for the different standard sizes. This real-time monitoring is complementary with scheduled qualification of clean rooms to be done at least every year.

In accordance with the normative constraints of the controlled environments, our continuous monitoring system gives an estimate of the number of fine particles present in the air. This system makes it possible to offer additional supervision to the qualifications of clean rooms carried out at least once a year.

Through better room management, most notably piloting ventilation according to activity in the room to save energy in less active periods while respecting standards.

All your devices can be connected to your BMS to centralize information.

Real-time monitoring can provide information outside of qualification periods, which allows for better air quality control. This can prove useful to prepare client audits or detect potential issues early.
