WinAir Pocket Filters

Viledon WinAir pocket filters are specifically designed for HVAC applications. Their efficient filter media are progressive or 3-layered progressive in structure and are made of break-resistant synthetic-organic fibres and microfibres - no glass fibres. They offer high functional reliability thanks to leakproof welded filter pockets which are foam-sealed into the PUR front frames. The filters are microbiologically inactive and offer no nutrient medium for micro-organic growth. They are non-corroding, moisture-resistant up to 100% relative humidity, thermally stable up to 70°C, with temporary peaks up to 80°C, and disposal-friendly. Viledon WinAir filters meet all hygiene requirements for HVAC systems and units.
