The CFS-5 supply filter ventilation unit (FVU) belongs to the “Protect” series. It is designed specifically for use in ventilation systems of small rooms (private houses, storage rooms) or apartments and combines a simple, concise design and powerful functionality. The main function is to clean and supply air into the room, it has two operating modes: filtration and filter ventilation. In the filter ventilation mode, the air supplied to the room is cleaned not only of dust but also of toxic warfare agents (TOA), highly toxic substances (HSS), radioactive dust (RD), biological aerosols (BA). The unit consists of the following main elements: a pre-filter unit, an electrically driven damper, an electric fan, a HEPA filter, a filter-absorber, which are combined into one compact housing.

Due to its design, excess pressure is provided in the room, which provides additional protection against dust, dirt and toxins that may be contained in the air from outside the room. At the same time, the high-performance fan operates with the minimum possible noise.

Compact dimensions allow it to be integrated into an existing ventilation system or used separately, and there is no need to allocate separate rooms.
