The patented FIRON fabric belongs to class G4. FIRON is an air filter that absorbs dust and small droplets. It is designed for ventilation and air-conditioning systems (working temperature is -50 ° C to 120 ° C) for heating and ventilation systems of industrial plants. It is also effective for filtering air in vehicles, garages and department stores. Also suitable for paint, spray booths and hoods. We produce FIRON filters for locomotives (engine rooms, fans, traction inverters, air-conditioning units) and for passenger cars (fans of heating units).
