Air FIlters
 
FILTER TESTING
 
Filter testing is performed as per prescribed international standards like ASHARE 52.2-1999 and ASHARE 52.1-1992 using the method of the arrestance dust spot efficiency, dust holding capacity and DOP (Dioctyl Phthalate) penetration; for dust particles up to 0.1 micron. Air dust samples are taken at a series of points that form a rectangular matrix across the face of the filter.
