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.

The FESP electrostatic filter is a new product from Alnor, designed for effective air purification in heat recovery systems. Thanks to its two-stage filtration technology, it removes over 95% of pollutants, including ePM1, ePM2.5 and ePM10 dust, providing high protection against smog. The steel pre-filter traps larger particles, while the advanced electrostatic filter with ionisation guarantees excellent efficiency with low flow resistance and minimal energy consumption. The device is maintenance-free, does not require cartridge replacement and can be cleaned with water. Its compact, insulated housing and high level of safety make the FESP filter the ideal solution for domestic mechanical ventilation.
The device is designed for domestic heat recovery systems:
