Pre Filter

Prefilters are designed to remove particles down to 3, 5 or 10 microns (identified as super,
standard and junior) at retention efficiencies 99%, 98% and 95% respectively when
tested as per bs 2831 using test dust ii. The fiber glass media (4, 2, 1 layers respectively for 3, 5 & 10 microns) inhibits growth of microorganisms, it is sandwiched between 2 layers of hdp mesh and reinforced with anodized aluminum grills on both sides. The filter matrix is housed in an g.i sheet frame with flanges and closed-cell neoprene gasket. Filters can be cleaned with water, mild detergents or compressed air in reverse direction.
