Product Description

Bernoulli Filter Self Cleaning Strainer For Liquids GRP Housing Material Pneumatic Butterfly Valve AF4000​





The bernoulli self-cleaning filter  which does not only use the backflush effect caused by the simple pressure drop to outside lower pressure than the working pressure – the Bernoulli self cleaning backflush filter creates it ́s own backflush effect in the gap between the cleaning disc and the strainer insert. The insert can be made out of wedged wire profiles or a perforated plate. In some special applications also stainless steel or alloy mesh is used. The wedged wire filter screen can be made out of stainless steel SS 316 or materials like super duplex or duplex SS. If perforated plate is used for filter degrees over or 1 mm than as well stainless steel and also duplex Ss or titanium perforated plates are used. This kind of self cleaning filters has following operating features.


1.Continuous filtration during all operation levels

2.Reliable cleaning function under heaviest solid loads

3.Filter mesh from 200-2000micron

4.Large particle size removal / Maximum particle size not limited by cleaning mechanism
