The Brink Renovent B-8W recuperator has air filters with a flat filter structure. As standard, the Brink Renovent B-8W recuperation units are fitted with G4 coarse filters that allow the capture of 60% of coarse particles from the air, i.e. leaves, insects, hair, sand, ash, fine sand, plant spores, pollen and other pollutants greater than 10 μm (micrometers). The operation of replacing the air filter set. It consists in removing a set of filters and inserting new ones for the supply and exhaust air from the facility through the mechanical ventilation system. Products made of synthetic filter media in accordance with the rules of using air filters may not be washed (washed) under any circumstances. Cleaning with a vacuum cleaner or by tapping in order to extend the interval between replacing the elements responsible for air filtration in the air handling unit is also not recommended. This reduces the efficiency of the recuperator's operation and lowers the level of comfort of using the mechanical ventilation system. In the initial stage of re-operation of the filters so cleaned, they release some of the contaminants that remained inside the previously collected. Settling on the surface of the heat exchanger, fans and ventilation ducts and then getting into the rooms of the building. Resulting in the need to clean the mechanical ventilation system. Accelerated wear of the elements responsible for the ventilation process and the recovery of heat energy from the air in the recuperator and increasing the amount of electricity consumed through the recuperation unit used. Filters for the Brink Renovent B-8W recuperator can be made in hard frames made of PVC plastic and galvanized sheet, ensuring high stability of the structure, and in a recyclable, soft cardboard.
