UPVC Cartridge Filter Housing (3 elements / 5 elements)
UPVC cartridge filter housing is made of UPVC and has a maximum working temperature of 45 °C. Filter housing bottom system and top cartridge positioning press plate adopt all-in-one design, which makes the cartridge installation easier while pressing the cartridge tightly to avoid internal leakage. The filter housing can accommodate 3 or 5 DOE flat type cartridges (or cartridges with standard 22 connector with an inner diameter of 28 mm and an outer diameter of 60–70 mm). It has successfully passed a 0–0.6 MPa 100,000-cycle fatigue test.

Plastic filter housing, also known as plastic cartridge filter housing or plastic precision filter, consists of an UPVC, PP, or PVDF housing and a filter bag, melt-blown filter cartridges, or high-flow filter cartridges inside. The housing features a stable structure, strong environmental 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.
Eigenschaften
- Plastic filter housings have good corrosion resistance and can be used in acidic and alkaline environments. They 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 all-in-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 installation 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 to vibrate when exhausting.
Categoria
By Filtration Mode
-
- Inside-out filter housing: Inside-out type refers to liquid flowing from the inside of the filter cartridge to the outside, and impurities being retained inside.
- Outside-in filter housing: Outside-in type refers to liquid flowing from the outside to the inside, and impurities being retained outside of the filter cartridge.
Per materiam
- Casa de filtru UPVC (clorură de polivinil rigid): Prezintă rezistență puternică la coroziune, rezistență scăzută a fluidului, rezistență mecanică ridicată și etanșeitate bună la apă.
- Casa de filtru PP (polipropilenă): Are rezistență la impact bună, stabilitate chimică bună și efect anti-coroziv bun.
- Casa de filtru PVDF (fluorură de poliviniliden): În afară de rezistența chimică bună și rezistența la temperaturi înalte, are, de asemenea, rezistență bună la oxidare, rezistență la intemperii și rezistență la coroziune.

Principium Operativum
It adopts outside-in filtration mode. The raw liquid flows into the filter housing from the inlet, and the filter cartridge uses tiny pores for mechanical filtration. Under pressure, the raw liquid passes through the filter material; filter residue remains on the cartridge wall, and filtrate exits through the cartridge to achieve filtration. The design—where water enters from the bottom center and flows upward—ensures even distribution across the cartridge and prevents cartridge deformation due to hydraulic impact, thereby avoiding internal leakage. Moreover, this configuration facilitates air discharge from the filter housing.
Cum tempus procedit, resistentia operativa eius paulatim crescit propter pollutionem materiarum interceptarum. Cum differentia pressionis aquae inter inlet et outlet superat valorem normalem operationis, cartucca substituenda est.
