Stainless Steel Filter Housings
Stainless steel filter housings are high-performance enclosures designed to hold and seal filter cartridges for water, chemical, or air filtration. Engineered from corrosion-resistant stainless steel (typically 304 or 316 grade), they are ideal for demanding environments where durability, hygiene, and pressure resistance are essential.
Key Features
Robust Construction: Built from SS304 or SS316 stainless steel for corrosion, chemical, and heat resistance.
High Pressure & Temperature Ratings: Suitable for extreme conditions; pressure ratings commonly up to 300 PSI and temperatures up to 250°F (121°C).
Multiple Cartridge Compatibility: Accepts standard DOE, SOE, and sanitary cartridges in various sizes.
Hygienic Design: Polished interiors and sanitary welds ensure compliance for food, beverage, and pharmaceutical use.
Secure Closure: Options include clamp, swing bolt, or threaded closures with EPDM, silicone, or Viton O-rings.
Applications
Industrial Water Filtration
For cooling towers, boiler feeds, and high-temperature water.
Chemical Processing
Compatible with solvents, acids, and caustics.
Food & Beverage Industry
Meets sanitary standards for wine, beer, and bottled water production.
Pharmaceutical & Biotech
Ideal for sterile or high-purity environments.
Marine & Offshore
Resists saltwater corrosion and extreme environmental conditions.
Available Configurations
| Type | Description |
|---|---|
| Single-Cartridge | Ideal for small-scale or point-of-use filtration |
| Multi-Cartridge | Supports 3, 5, 7, 12, or more filters for high-volume systems |
| Sanitary Clamp | Tool-free access for clean-in-place systems |
| Code 7 / Code 222 | Accepts keyed cartridge ends for ultra-hygienic setups |
Benefits of Stainless Steel Housings
✔
Extreme Durability: Withstands corrosive fluids, high pressure, and temperature.
Long-Term Investment: Resistant to cracking, rust, and wear—unlike plastic housings.
✔
✔
Broad Chemical Compatibility: Ideal for aggressive or hazardous liquids.
Hygienic Compliance: Supports FDA, NSF, and 3-A standards (when applicable).
✔
✔
Easy Maintenance: Polished surfaces and drain ports simplify cleaning and sanitization.
How to Choose the Right Stainless Steel Housing
| Consideration | Details |
|---|---|
| Flow Rate | Ensure size and port configuration support system demand |
| Filter Type | Match DOE or SOE cartridges with housing spec |
| Material Grade | SS304 for standard use, SS316 for corrosive or high-purity systems |
| Closure Type | Clamp for sanitary use, swing bolt for industrial security |
| Certifications | Look for NSF, 3-A, or FDA compliance when required |
Maintenance & Best Practices
Regularly inspect seals and gaskets for wear or chemical compatibility.
Clean housings during each filter change with CIP or SIP methods.
Use torque-controlled tools to avoid overtightening closures.
Replace O-rings annually or as needed for airtight sealing.
Frequently Asked Questions
1. What is a stainless steel filter housing used for?
Stainless steel filter housings are used in water, chemical, food, pharmaceutical, and industrial filtration systems. They hold filter cartridges and provide a secure, pressure-resistant environment for fluid or air filtration.
2. What’s the difference between SS304 and SS316 housings?
SS304 is standard-grade stainless steel suitable for most water and food-grade applications. SS316 offers greater corrosion resistance, especially against chlorides, acids, and saltwater—making it ideal for marine and chemical processing environments.
3. Are stainless steel housings better than plastic?
Yes, stainless steel housings are more durable, heat-resistant, and corrosion-resistant. They are preferred in high-pressure, high-temperature, or sanitary-critical applications where plastic may fail.
4. What types of cartridges fit in stainless steel housings?
They can accommodate standard DOE (double open end) cartridges or SOE (single open end) cartridges like Code 7, Code 222, or Code 226. Always match the cartridge type to the housing specification.
5. Can stainless steel filter housings be used for hot water filtration?
Yes, many stainless steel housings are rated for temperatures up to 250°F (121°C), making them suitable for hot water, steam sterilization, or CIP/SIP cleaning processes.
6. Do these housings require special maintenance?
Stainless steel housings require periodic inspection for gasket wear and residue buildup. Regular cleaning, especially in sanitary applications, ensures system hygiene and performance.
7. Are stainless steel filter housings NSF or FDA certified?
Many models are made from FDA-compliant materials or carry NSF certifications. Check product specifications for exact compliance with your regulatory needs.
8. What industries typically use stainless steel filter housings?
They are used in industries such as water treatment, beverage production, pharmaceuticals, dairy processing, power generation, oil & gas, and marine systems.
9. Are single or multi-cartridge housings better?
Single-cartridge housings are ideal for low-flow or point-of-use systems, while multi-cartridge housings suit high-flow or large-volume filtration where reduced downtime and extended capacity are needed.
10. Can I install a stainless steel housing vertically or horizontally?
Most housings are designed for vertical installation to aid sediment settling and drainage. Some models may allow horizontal mounting with proper flow configuration—always follow the manufacturer’s guidance.
