Particulate filter air terminal device type TFW for wall installation as final filter stage and for air distribution.
Fitting of filter elements for the separation of suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply or extract air.
Casing with clamping mechanism with 2 fixing points for filter elements.
As standard, the casings are equipped with a sealing integrity test facility and pressure measurement points for monitoring the operating differential pressure.
For the fitting of Mini Pleat filter panels with a flat seal. Ventilation grille type SL made of sheet steel, powder-coated RAL 9010, pure white, or type ASL made of aluminium.
Leakage test for each casing.
