Our 20-inch standard tertiary filter housing (TOP-201T-LTBB) is a crucial filter housing for high-flow tertiary water purification systems. Both the cover and filter cartridge are made of polypropylene and PET through precision injection molding. Polypropylene offers excellent chemical resistance, effectively resisting the effects of acids and alkalis in water. It also offers excellent temperature resistance, ensuring stable operation within a water temperature range of 4.4°C to 49°C. The PET portion offers excellent light transmittance, allowing users to easily check the filter status. The blue filter cartridge reduces light ingress, minimizing the risk of algae growth within the housing and extending the filter life.
The double O-ring design (NBR material) ensures excellent sealing performance and is rigorously tested to ensure leak-free operation under operating pressure. BSP/NPT thread connections allow for flexible connection options to meet specific installation requirements, compatibility with various piping systems, and ease of installation, reducing both difficulty and time.
Strict quality control measures are implemented throughout the production process. Every filter housing component undergoes dimensional inspection to ensure assembly accuracy. Finished products undergo pressure and seal testing to ensure performance meets standards. For example, the pressure test simulates maximum operating and burst pressures to ensure the housing operates safely even under extreme pressures.
This filter housing is suitable for applications requiring high-flow three-stage filtration and mitigating algae growth, such as large commercial water purifiers and high-end household water purifiers. It can be paired with various 20-inch filter cartridges to form a three-stage filtration system, providing users with deeper and more comprehensive water purification services. It is a high-quality component of choice for high-flow three-stage water purification systems.
