FILTER CARTRIDGES type GD and GDW



In their standard version gas filters are equipped with cellulose filter cartridges of GD and GDW type. The separation of solid particles from gas is held in a star-pleated, impregnated in single-stage resin, cellulose paper sheet. This construction makes the cartridge resistant to moisture and mechanical damage, e.g. to tear. In comparison to felt cartridges, cellulose cartridges provide 4,5 times greater active filtering area. Both the internal and external side of the filtering material is protected with perforated metal sheet.
The photo blow shows cartridges protected with galvanised sheet. Cartridges of this type are not resistant against aggressive agents like biogas. Aggressive or sour and acid gases are filtered with cartridges protected with stainless steel metal sheet. Both heads of the filter cartridges are equipped with felt rings, separating contaminated gas side and clean gas side of the filter. The dimensions of filter cartridges are presented in the table.
Filter cartridges for standard applications separate particles of 5 µm, while optional configurations separate particles of 2 µm.
