Check the air quality in the classroom. Live.
Clean akr in the classroom is not just a promise – it is a measurable result. That is why we have launched online air quality monitoring at Primary School No. 6 in Sokołów Podlaski, Poland.
The monitoring system allows you to check and compare air quality parameters in two classrooms – one equipped with a TeachAIR heat recovery ventilation unit and one without mechanical ventilation. Real-time data shows how ventilation can affect the conditions in which students and teachers spend many hours every day.
Two classrooms. The same conditions. Different air quality.
The monitoring system allows you to compare air quality in real time:
Classroom with TeachAIR. Stable indoor conditions and controlled ventilation, with live data on CO₂ concentration, temperature, humidity and PM1, PM2.5 and PM10 particulate matter.
Classroom without a heat recovery ventilation unit. A reference point that allows you to see how indoor air parameters change without mechanical ventilation with heat recovery.
All key data in one place
The monitoring platform provides current and historical data on:
TeachAIR Monitoring – see how ventilation performs in real conditions
You don't have to rely solely on declarations or catalogue specifications. Check real data from a working installation and see the difference between a classroom equipped with TeachAIR and one without a heat recovery ventilation unit. You can monitor the data LIVE or analyse it over selected periods: 24 hours, 7 days or any custom date range.

The CWS-ODA intake unit and the CWS-EHA exhaust unit are a new family of wall-mounted ventilation system terminations in the Alnor lineup—for connections ranging from Ø100 to Ø315 mm.
These components are designed for residential and small commercial mechanical ventilation systems with heat recovery. The CWS-ODA intake unit is responsible for drawing in outdoor air and providing initial protection for the system, while the CWS-EHA exhaust unit ensures the efficient removal of air from the building.
Advantages of the CWS-ODA and CWS-EHA:
For certain connection diameters, various faceplate sizes are available (from 160 × 160 mm to 400 × 400 mm), and the recommended maximum airflow rate varies with the active surface area—from 125 to 800 m³/h. This allows the outlet to be selected not only based on the duct diameter, but above all on the actual flow rate in the system. Detailed technical data, pressure loss characteristics, and a complete list of variants can be found in the product data sheets for CWS-ODA and CWS-EHA.
We are pleased to announce the expansion of the Alnor lineup with a new version of the FLX-EPP-R-90 series distribution boxes, designed for use with semi-rigid ventilation ducts with a diameter of 90 mm.
FLX-EPP-R distribution boxes are used in residential mechanical ventilation systems, where they function as a manifold that distributes air to individual rooms via semi-rigid ventilation ducts. In typical installations, one to two manifolds are used on the supply side and a corresponding number on the exhaust side.
Key advantages of the FLX-EPP-R-90 boxes
75-mm-diameter conduits are often chosen in single-family housing due to the ease with which they can be routed through thin floor or ceiling layers. In contrast, 90-mm conduits require more installation space but allow for a reduction in the number of channels in the system, which can significantly simplify its design and installation.
The introduction of the new FLX-EPP-R-90 model complements the existing range of manifolds designed for Ø75 mm ducts. This gives designers and installers even greater flexibility in selecting solutions tailored to the requirements of a specific project.
The FLX-EPP-R-90 represents the next step in the development of Alnor’s ventilation systems—modern, durable, and tailored to the needs of contemporary construction.
We have expanded our range of round ducts and ventilation fittings made of expanded polypropylene (EPP). New diameters with a wall thickness of 15 mm—150 mm and 180 mm—have been added to the available options. This allows for even better adaptation of the system to a variety of ventilation system configurations.
We have also introduced a significant design change—EPP ducts are now manufactured as a single piece. This solution enhances installation convenience and contributes to the high quality and durability of the system.
Key features of EPP products:
The new EPP ducts are a solution that combines functionality, energy efficiency, and ease of installation. If you have any questions or need detailed technical information, please feel free to contact us.
New in Alnor’s offer: FLX-EPP 90 mm plenum boxes designed to improve the efficiency of ventilation systems thanks to a larger diameter and EPP technology.
A larger duct cross-section means lower airflow resistance and reduced energy consumption – in many cases, a single 90 mm duct can replace two 75 mm ducts. This results in a simpler installation and better performance.
The EPP material, combined with lower air velocities, ensures quiet system operation, while a reduced number of connections minimizes the risk of leakage. The “click-fit” system with seals guarantees high airtightness (Class D).
It is an ideal solution for rooms with higher air demand, such as living rooms or kitchens.
Choose performance, comfort, and reliability with the EPP 90 mm system.
