Pre-filters protect components from debris. They feature larger through holes than other pre-filters to avoid loading filters with fine crystals while still filtering solids that could damage pumps. Their filters can be removed and cleaned without disconnecting liquid lines. White Knight pumps damaged by passing solids while using Catchers™ are repaired under warranty.
iPolymer PTFE disc filters utilize replaceable filter elements, which form a continuous mat of PTFE fibers. These fibers are fused together to form a screen-like membrane structure. The resultant membrane is hydrophobic and hence aqueous suspensions must be filtered at high rates to overcome surface tension. Because of the non-stick characteristics of PTFE, the natural lubricity of all-wetted surfaces, and the easy replacement of filter elements, entrapped contaminates may be easily removed.
