Filter Elements GD

The standard version has gas filters (high and medium pressure) with cellulose filter elements, type GD, which use a star-shaped cellulose paper impregnated with resol. The insert is resistant against humidity and mechanical damages (e.g. breaking). The filter elements made from star-shaped paper have an active filtration surface that is 4.5 times larger than that of standard types. The filtration material is protected with a perforated plate on the inside and outside. The figure shows elements with galvanised plates.

Filter elements of this type are not sufficiently resistant to aggressive substances, such as bio-gas. Filtering of aggressive or caustic gases requires filter elements protected with a protective net made of stainless steel. Both bases of the filter insert are equipped with felt rings that make sure the contaminated gas on the inlet side is separated from the "clean" area. The measurements of the elements are listed in the table. Standard elements can reach a cleaning precision of up to 5 μm. Upon enquiry, we supply optional elements  ensuring up to 0.5 μm at 99 %.
