The products are suited for high air volume applications which are heavily contaminated. The Filtrair G3 HVAC media combine a high dust holding capacity with a low pressure drop and are therefore extremely cost effective with a long filter life. Synthetic fiber-based filter media developed and produced at Filtrair high-tech media plant based in The Netherlands. The filter media are constructed from selected high performance, non-breakable fibers in a progressive density multi-layering technique to ensure high depth loading with optimal lowest pressure drop performance, to achieve gravimetric arrestance in accordance with EN 779:2002 standard ratings. VNF-290 and PSF-200 are thermally bonded to prevent fiber release. The clean air sides can be imprinted for easy identification to ensure the correct installation in pad, roll or pocket format. PSF-200 requires minimum order quantities
