Cartridge filter housing
Filter cartridges are long, slender elements that are suspended vertically in a housing. Because many of them fit side by side, a large filter area is achieved on a small cross-section – that is the reason for choosing this design.
In terms of the housing, the cartridge filter is a simplex strainer: the same upright cylinder, the same cover, the same production. What changes is the element and its suspension.

Operating principle
The decisive value in filtration is not the filtration grade alone, but the area. The more area is available, the more slowly the medium flows through, the lower the pressure loss and the longer the element lasts.
A strainer basket offers the area of its shell. Cartridges offer the sum of their individual areas – many times as much for the same housing diameter. That is why this design is chosen when fine separation is needed and a high flow still has to pass through.
What we supply
We do not design the cartridge filter for you; we build it to your specifications. Once cartridge length, connection type and number are fixed, we make the housing to suit. It is welded, in carbon steel or stainless steel, with cover, suspension, vent and the connections the installation point requires. On request we also procure filter cartridges in stainless steel, polypropylene or another material.
The cartridges themselves are consumables. On request we procure them to your specification, so that the housing and the element match from the start.
The area. Both separate finely, but a bag offers only its own shell area, while several cartridges side by side provide many times as much. For a low flow rate the bag is the simpler solution; as soon as a high flow has to pass through, it does not last long enough.
Both are possible. We make the housing – to your specification for cartridge length, connection type and number. The cartridges are consumables and are procured to your specification on request.
That depends on the internal dimensions and the cover opening. Tell us both, as well as the cartridges you want to use – we will then check whether the suspension fits into the existing housing.
