What Is Filter Casing?
FiltEdge’s filter casing, also known as filter housing, includes bag filter, cartridge filter, basket filter, backwash filter, scraper filter and candle filter. They have different characteristics and can be used for you in chemical, pharmaceutical, food, water treatment and other industries. They can efficiently filter corrosive, high solid content, viscous and high flow rate liquids, and can also recover high value solids.
Filter Casing Type
More than a hundred kinds of filter casing are available for you to choose, and we can also customize filter casing for you according to your special working conditions and production environment.
Bag Filter HousingA single filter can be installed with 1-32 bags, with a maximum flow rate of 5000+GPM, quick-opening and labor-saving structure, which can provide you with coarse filtration and fine filtration, with a super cost-effective price.
Cartridge Filter HousingIt can provide ultra-high precision of 0.1μm, improve the product filtration quality for you, and also do pre-filtration for nanofiltration, reverse osmosis, etc. to protect your equipment.
Basket Filter HousingMade of stainless steel, durable, cost-effective filtration solution for coarse filtration of large flow liquids.
- Backwashing Filter
Full-automatic filter, for large flow, low viscosity liquid, not only saves you labor cost, but also improves your production efficiency.

Generally speaking, you need to change the filter bag or cartridge once every 1-4 months, depending on the quality of the slurry you are filtering. The most intuitive is to check the change value of the differential pressure gauge during the maintenance of the equipment to see if the filter bag/element needs to be replaced.
It depends on what type of filter casing you are using. If you use manual bag/cartridge filter housing, you can directly replace the filter bag/cartridge with different precision to achieve the purpose of adjusting the precision. If you are using a fully automatic filter, you need to buy other precision screens or cartridges from the manufacturer and replace them to achieve the purpose of adjusting the precision. Comparatively speaking manual filter casing are easier to adjust the precision than fully automatic ones.
It mainly depends on whether you are using a manual filter or a full-automatic filter. Manual filters, such as bag-type quick-opening filters/cartridge filters, these filters need to open the cover of the equipment to replace the filter bag cartridge and re-install it during maintenance and cleaning, so it is necessary to completely interrupt the filtration and production to eliminate the pressure. If you use a full-automatic filter housing, filtration, cleaning, and slag removal are all automatic operation, it is possible to run 24 hours a day without interruption, without the need to interrupt your production.
FiltEdge’s filter casing can be customized with thickened design, so that the pressure-bearing capacity can reach 2.5 MPa. The temperature of our filter casing is mainly affected by the sealing material, and usually the housing material with stainless steel can reach 350°C. So the temperature that the seals can withstand is the key to the temperature that the whole filter can withstand, which is selected according to your working conditions. Our seals are made of different materials and can withstand up to 150℃.
