Wound cartridge filters are a type of depth filter commonly used in various industries for liquid filtration applications. They are known for their high dirt-holding capacity, making them suitable for pre-filtration applications and extending the life of other downstream filters in the system.
Working of Wound Filter Cartridge
Filter elements are made using a method called cold isostatic pressing. Here's how it works: metal powder is put into a tool that squeezes it using high pressure. The compact is then taken out of the tool and put in a furnace, where the sintering cycle is carried out.
This makes the metal particles stick together tightly, forming a single, interconnected piece.
These are made by sintering multiple layers of woven metal mesh kept over each other, and then rolled to the desired thickness. The filtration rating is decided by the pore size of the controlling layer in this case.
he filter element is typically housed in a metal frame for support and protection. The frame may also have connections for attaching the filter to other equipment. In this case, as the pore size is determined by the controlling layer, the limiting factor for the filtration rating is the quality of the weaving and its fineness.
