ALov* pbois shims mcUsb of |ulllt nisspsd grid. Strands and grids are scientifically sized and placed (or IwiMing matimnm dirt load. Filter pack has larger grid openings on air mlet side progressing to smaller grid openings on air outlet side. Prevents face loading and choke-off of air stream. Accomplishes uni form depth loading all through the pack. Every grid, every strand does ita part. TURBULENCE AIR CLEANING ACTION. Dirt is slammed into the flat strands of mesh vrheie it is caught and held by talon-like edges of these grids. Precision stamped openings force air to travel many times filter depth from inlet to outlet side ... for high efficiency air cleaning. . LOWER AND SLOWER STATIC PRESSURE RISE PER CRAM OP DIRT LOAD. Filter pack catches, and holds dirt without strangling air stream. Filter remains in service longer: (1) without sharp increase in resistance (2) with fewer cleanings (3) with power costs held down. HIGH VELOCITY APPLICATION ... UP TO 1,000 FPM. Using turbulence air cleaning action (instead of screening or strain ing action) makes Evans filters particularly well suited to extremely high velocity requirements. The higher the velocity ... the dirt is slammed into the mesh where it is caught and held by the talon-like edges of the strands. Filter's efficiency rises as velocities rise. DOUBLE ACTION ADHESIVE. Works as adhesive while filter is in service. Becomes a detergent and helps wash filter when water is flooded on. IMPORTANT... When Evans filter fluid is used filters can be washed with tap water. FILTER CAPACITY CHART--CRH DELIVERY Gasket pressure locks filter into frame. No springs, latches or lock ing attachments. Slide filter into frame. Gasket automatically grips it securely.
