Pullner Stainless Steel Filter Housing Gallery
A stainless steel filter housing is a pressure-type filtration vessel consisting of a filter cylinder, cylinder cover, quick-opening mechanism, and an internal support basket or tube that holds the filter element. The upper cover uses a cantilever design for easy access, and the flange is secured with stainless steel tilting screws for a reliable seal.
Process liquid enters through the inlet and passes through the filter cartridge, which captures particles at the required micron rating. Clean filtrate exits through the outlet. Replacing filter elements is fast — no tools required for most designs — and the housing itself requires minimal maintenance.
Pullner manufactures stainless steel filter housings in single and multi-element configurations, including high flow water filter housings, bag filter housings, and pleated filter cartridge housings.

Frequently Asked Questions
What is a stainless steel filter housing?
A stainless steel filter housing is a pressure vessel that holds one or more filter elements (cartridges or bags) in a sealed chamber. Liquid enters through the inlet, passes through the element at a specific micron rating, and exits as filtrate. Contaminants are captured until the element is replaced.
What are the advantages of stainless steel filter housings?
Stainless steel filter housings offer four main benefits: pressure stability (SS304 and SS316L withstand up to 31.7 MPa), effective prefiltration, simple operation with quick cartridge changeout or optional backwash, and long-term cost savings by protecting downstream equipment.
Which industries use stainless steel filter housings?
Power plants, seawater desalination, chemical and petrochemical, food and beverage, pharmaceuticals, oil and gas, pulp and paper, automotive, and agriculture. They serve as prefiltration before reverse osmosis and for protecting downstream equipment.
Which filter housings are compatible with my replacement cartridges?
Pullner housings accept Type 222, Type 226, double flush end, and similar cartridges in 10″, 20″, 30″, 40″, 60″, and 70″ lengths. Compatible with Pullner and Pall, 3M, and Parker replacement cartridges. Capacity from 1 to 150 cartridges. See the specifications table above for details.
What materials does Pullner use for filter housings?
SS304, SS316L, duplex steel, super duplex, or carbon steel. SS316L is recommended for corrosive and seawater applications; SS304 for most industrial uses. Material selection depends on operating conditions.
When should I replace the filters in a stainless steel filter housing?
Replace when differential pressure rises (check the pressure gauge). With backwash, try backwashing first; if flow stays low after repeated washing, replace the elements. Without backwash, shut down, open the housing, and replace the elements.
How do I replace the filter in a stainless steel filter housing?
- Shut down and isolate the housing.
- Open the vent to relieve pressure.
- Remove the cover and old element.
- Inspect the new element (O-ring, structure).
- Install the new element, close the vent, and restart.
How can I get a quote for a stainless steel filter housing?
Use the contact form on this page or the main contact page. Provide system parameters (flow rate, pressure, cartridge type, material grade). We aim to respond within 10 hours.
What is the minimum order for Pullner filter housings?
