BZZ backflow prevention device
The BZZ damper prevents uncontrolled air flow in the opposite direction when the ventilation system is switched off.
CSR-B EC W, CSR-B EC Zero Plus W, CSR-B EC NFC W controller
Controllers of the CSR-B series are constant pressure regulators designed for cooperation with duct and roof fans with EC motors. By continuously controlling the fan speed, they ensure constant pressure in the ventilation ducting. Based on a PI controller, CSR-B controllers have the option to set a constant fan power and programmable upper and lower fan control limits.

Aircycle 5.1 is a continuous running heat recovery unit, transfers heat from humid air extracted from wet rooms to warm incoming fresh air which is ducted to habitable rooms. Thanks to the easy-to-fit air distribution system each single ambient can be properly ventilate: the boost function enables rapid extract of increased moisture or pollutant levels. It also provides discrete installation and very quite operation. Suitable for large houses.
Rotary chimney cowl that uses wind power to support the chimney draught. Equipped with a low-power brushless motor for its effective stabilisation. Dedicated to single and multi-family dwellings.
