Eimco-K.C.P. Precoat filter is a continuous rotary vacuum drum type clarification or polishing filter. It is commonly applied for clarification of difficult filtering, low solids slurries on a continuous basis. Filtration is accomplished through a predeposited bed of diatomaceous earth or similar material. The slurry solids deposited by vacuum on the surface of this bed are removed on each revolution. Available with vapor tight hoods for special applications. Scrapper blade operates independently of drum driver to give greater flexibility with "lathe prevision" movement.
