Filter Cartridges Double Open End (DOE)
Filter Cartridges Double Open End (DOE)
Double open-end filtering cartridges (DOE) as the name suggests, are open on both sides and guarantee sealing thanks to the direct compression carried out by the filter container itself. The sealing system generally uses a scoring mechanism on both ends of the cartridge, one with a blind side and the other with a hole leading to the side of the filtrate. The edges of the engraver are pressed against the end of the cartridge using different types of compression device, commonly spring or screw. The disadvantage of the DOE system is that the scoring seal mechanisms are relatively rough and susceptible to damage or installation errors by the operator leading to a potential bypass of the filter cartridge and thus a reduction in the efficiency of the filtration system. This type of cartridge is not recommended if you require 5 µm absolute and lower filtration efficiencies, when operation is expected at high temperatures or where sanitation is required.
Double Open End (DOE) cartridges are ideal for non-critical filtration and prefiltration applications and for general purposes, where operating economy is of primary importance. Generally, there are the two configurations in extruded polypropylene with direct incision on the filtering material or pleated with a rigid structure and flat gaskets on both sides.
