Factory Direct Supply Good Performance Self Cleaning Filter for Isocyanate and Polyurethane

Working principle

Self-cleaning filter is also named the doctor blade self-cleaning filter, the medium goes into barrel directly from inlet, is filtered through filter element gap from outside to inside, the medium flows to upper port from bottom to top. Dreg which size is more than filter disc gap is intercepted, when the filter disc component runs some time, the filter gap may be jammed by dreg, the driving unit would drive filter element component rotate (each doctor blade just inserts into the gap of filter element component) to clear away dreg from the filter disc gap and keep the filter element gap no block. When the bottom barrel is stored many dregs, only open the eject valve, dregs can be drained out, the processing pressure would return normal soon.

Both filtering disc and doctor blade are made of stainless steel or high quality manganese steel. And the doctor blade has been treated by by special surface strengthening processes. The performance of pressure-resistance and durability is really no substitute by any other filters. The granular material hidden in the liquid is disintegrated by rotating doctor blades.
