UPVC Cartridge Filter Housing(8 elements /9 elements)
UPVC cartridge filter housing adopts bottom and top cartridge positioning press plate all-in-one design, which makes the cartridge installation easier while pressing
the cartridge tightly to avoid internal leakage. The filter housing can accommodate 8 or 9 DOE flat type cartridges (or cartridges with standard 222 connector) with an inner diameter of 28 mm and an outer diameter of 60-70 mm. Maximum working temperature: 45 C. It has achieved 0-0.6 MPa 10o,oo0 times recycle fatigue test successfully.

Plastic filter housing,also known as plastic cartridge filter housing or plastic precision filters,is composed of an UPVC, PP, PVDF housing and filter bag, melt blown filter cartridges or high flow filter cartridges inside.The housing featuresstablestructure,strongenvironmental adaptability and durability.
It is mainly installed after multi-media pretreatment filtration and before membrane filtration equipment such as reverse osmosis and ultrafiltration. It is used to filter out the residual trace suspended solids, colloids, microorganisms in the water, as well as fine materials (such as tiny quartz sand, activated carbon particles, etc.) after multi-media filtration, to ensure the water filtration accuracy and protect the membrane filtration element from damage by large particles. It has certain price advantages when compared with stainless steel filter housings and FRP filter housings.
Features
- Plastic fiter housings have good corrosion resistance and can be used in acid and alkalineenvironments.It can be applied to fields where stainless steel and carbon steel cannot enter.
- The filter housing features compact structure, beautiful appearance, simple installation and operation, and small footprint.
- The filter housings adopt allin-one molding and are produced in a standardized manner, which makes it easy to replace and maintain.
- The filter cover and the body are connected and sealed with wide threads or eyebolts, which not only ensures the intact sealing performance of the filter housing,but also brings convenience and speed to the disassembly and installtion of the replacement filter cartridges.
- The pressure gauge and exhaust valve are separately installed to make operation easier and will not cause the pressure gauge vibrating when exhausting.

By Filtration Mode
-
- Inside-out filter housing：Inside-out type refers to liquid flows from the filter cartridge inside to the outside and impurities are retained inside
- Outside-in filter housing: Outside-in type refers to liquid flows from outside to inside and impurities are retained outside of the filter cartridge.
By Material
- UPVC (rigid polyvinyl chloride) filter housing:It features strong corrosion resistance, low fluid resistance,high mechanical strength and good water tightness.
- PP (polypropylene) filter housing:It has good impact strength, good chemical stability and good anti-corrosion effect.
- PVDF (polyvinylidene fluoride) filter housing:In addition to good chemical resistance and high temperature resistance, it also has good oxidation resistance, weather resistance and corrosion resistance.

UPVC Cartridge Filter Housing(8 elements /9 elements)
UPVC cartridge filter housing adopts bottom and top cartridge positioning press plate all-in-one design, which makes the cartridge installation easier while pressing
the cartridge tightly to avoid internal leakage. The filter housing can accommodate 8 or 9 DOE flat type cartridges (or cartridges with standard 222 connector) with an inner diameter of 28 mm and an outer diameter of 60-70 mm. Maximum working temperature: 45 C. It has achieved 0-0.6 MPa 10o,oo0 times recycle fatigue test successfully.
Working Principle
It adopts outside-in filtration mode. The raw liquid flows into the filter housing from the inlet, and the cartridge uses tiny pores for mechanical filtration. Under the action of pressure, the raw liquid passes through the filter material, filter residue is left on the wall of the cartridge, and filtrate flows out through the cartridge to achieve the purpose of filtration. The design of water entering from the bottom center and moving upward makes the water evenly distributed on the cartridge and the cartridge will not deform because of water impact,causing internal leakage. Besides, it is also conducive to discharge the air in the filter housing.
As time goes by, its operating resistance gradually rises due to the pollution of the intercepted materials. When the water pressure difference between the inlet and outlet is higher
than the normal working value, the cartridge should be replaced.
