All Arctic Air solutions pre filters are manufactured to very high standards conforming to P1 G4 EN 779 and now ISO 16890. The frames are made from anodised aluminium or galvanised steel therefore making them very rigid and resistant to the harsh operating conditions typical on heavy duty equipment working in challenging conditions.
The filtering media is of high quality and pleated ensuring maximum filtering surface area. Pre filters are the first line of protection against particulate matter and protect the HEPA and Carbon filter from premature blockages.
