What Is Filter Housing?
A filter housing is a pressure-resistant casing that securely holds filter cartridges or bags. It provides a sealed environment through which liquids (or gases) flow, allowing contaminants to be captured by internal filter elements. The purified output then exits through the outlet port, ready for use or further processing.
Filter housings are widely used across industries such as:
Water treatment and desalination
Oil and gas
Food and beverage
Pharmaceuticals
Chemical manufacturing
Electronics
Types of Filter Housing
1. Single Cartridge Filter Housing
Compact and cost-effective, single cartridge housings are ideal for small systems or point-of-use filtration where limited space and lower flow rates are involved.
2. Multi-Cartridge Filter Housing
These housings accommodate multiple cartridges in parallel, making them perfect for higher flow applications or staged filtration processes.
3. Bag Filter Housing
Designed for use with filter bags instead of cartridges, these housings are ideal for filtering large volumes of fluid or removing coarse contaminants in chemical, water treatment, and paint industries.
4. Single vs. Multi-Bag Filter Housing
Single Bag Filter Housing: Suitable for lower flow rates and batch operations; economical and easy to maintain.
Multi-Bag Filter Housing: Offers increased flow capacity, longer run time, and reduced frequency of filter changes. Ideal for continuous processes and larger systems.
5. Sanitary Filter Housing
Used in pharmaceutical and food-grade applications, sanitary housings are built with polished interiors and FDA-compliant materials for maximum cleanliness.
6. High Flow Filter Housing
High flow filter housings are designed to accommodate large-diameter cartridges, allowing significantly higher flow rates and dirt-holding capacity with a smaller footprint. They are widely used in industrial water treatment, cooling systems, and RO pretreatment processes where space and performance efficiency are critical.
7. Basket Filter Housing
Basket filter housings use a perforated or mesh-lined basket to capture large debris and solid contaminants. These are particularly suitable for pre-filtration and coarse particle removal in pipeline protection, fuel filtration, and industrial fluid systems.
8. Custom and Application-Specific Housings
From fuel filtration to machine coolant systems, customized filter housings are available to match highly specific industrial needs.
