Internally Threaded Filter Housing for Water Purifiers

Core Functions

The primary functions of an internally threaded filter housing for water purifiers in a water purifier are to house the filter cartridge, withstand pressure and guide water flow, and provide sealing and protection. The interior of the housing can accommodate various cartridges—ranging from pretreatment filters such as PP cotton and activated carbon to core filtration elements like ultrafiltration membranes or RO membranes—thereby serving as a stable vessel for the filtration process. Its pressure-bearing and flow-guiding capabilities enable it to withstand the internal water pressure generated during the purifier's operation, while directing the water flow along a specific path through the filter cartridge to ensure efficient filtration. Furthermore, the housing features an integrated sealing structure that prevents water leakage; concurrently, it shields the internal filter cartridge from external contamination, thereby extending the cartridge's service life.

Key Features

1. Material: Primarily constructed from food-grade PP material, offering excellent corrosion resistance and high-temperature durability. It is odorless and complies with safety standards for materials in contact with drinking water.
2. Structural Design: Features a reinforced rib structure capable of withstanding operating water pressures ranging from 0.1 to 0.4 MPa. Highly resistant to cracking, it is suitable for use in the diverse water pressure environments found in various household water purification systems.
3. Easy Assembly/Disassembly: The housing body and cap utilize a threaded connection; with the aid of a dedicated wrench, the unit can be easily disassembled, facilitating convenient periodic filter cartridge replacement and cleaning.

Applicable Scenarios

The pre-treatment stage for home-use RO (Reverse Osmosis) and Ultrafiltration water purifiers, housing PP cotton and pre-carbon filter cartridges.
The core filtration unit for central water purification systems, accommodating high-flow filter cartridges to meet whole-house water purification needs.
A filtration module for commercial water purification systems, designed to facilitate the installation and replacement of filter cartridges in high-volume water supply environments.
