PFB Series coarse filters (equipped with FyaR-type filter cartridges) are designed specifically for installation in the air ducts of supply ventilation systems. In addition, their design allows them to be used as airflow distributors.
The primary purpose of these devices is to be installed at the inlet of the supply air system (before the air duct) to ensure a steady supply of clean air to bomb shelters and shelters.
The filter elements effectively (up to 90%) trap dust, solid aerosol impurities from combustion products, and other types of contaminants that may enter the shelter’s ventilation system.
