Our 5-inch Atlas single-stage filter housing (TOP-05S5-BT) is the core filter housing for small water purification systems. The cover is precision-injected polypropylene, offering excellent chemical resistance and protection against common waterborne chemicals. The filter cartridge is made of PET, which not only offers excellent light transmittance, allowing users to visually inspect the contamination level within the filter element, but also offers excellent impact resistance, ensuring the cartridge's stability during use.
The NBR O-ring undergoes rigorous sealing testing to ensure a leak-proof seal within the operating pressure range, providing a reliable seal for the filter housing. Universal BSP threads are used for connection, allowing users to choose from a variety of interface specifications to meet specific installation requirements. This adapts to a variety of piping systems, making installation simple and efficient, without the need for complex tools.
Our factory adheres to a strict quality management system, with rigorous quality inspections at every stage, from raw material procurement to finished product assembly. For example, the filter housing undergoes pressure testing to simulate maximum operating and burst pressures, ensuring safe operation even under extreme pressures. The O-ring seal is 100% inspected to prevent leaks.
This filter housing is suitable for small household and commercial water purifiers. It can be paired with a 5-inch PP cotton or activated carbon filter element to form a single-stage filtration system, providing initial water purification. It is an indispensable component in small water purification systems.
