Frequently Asked Questions (FAQ)

1. What materials are K Filter Cartridge Filter Housing available in?

We manufacture in SUS304, SUS316,SUS316L stainless steel and Super Duplex for superior corrosion resistance, as well as heavy-duty Carbon Steel for high-pressure industrial applications.

2. Can your multi Cartridge Filter Housing handle large-scale flow rates?

Yes. Our multi Cartridge Filter Housing are designed for high-capacity filtration, supporting up to 263 elements per unit. They are compatible with element lengths from 10 inches up to 50 inches.

3. Do you support both SOE and DOE connections?

Absolutely. Our housings are engineered to be versatile, supporting both Single Open-End (SOE) and Double Open-End (DOE) cartridge configurations to fit your existing process lines.

4. How does K Filter ensure quality for international markets like Europe and the Middle East? 

Every unit undergoes strict pressure testing and quality inspections. Our Cartridge Filter Housing are designed to be stain-resistant and capable of operating under extreme temperatures and pressures, meeting the global standards required for European medical use and Middle Eastern industrial environments.

5. What types of inlet and outlet connections do you offer for cartridge housings? 

We provide a full range of global standard connections, including ANSI/DIN Flanges, NPT/BSP Threads, Sanitary Tri-Clamps, and Victaulic Grooved ends. Our housings can be customized to match your specific pipe size and pressure rating.

6.Can I customize the position of the inlet and outlet? 

Yes. As a direct manufacturer, K Filter can customize the nozzle orientation (Side-In/Side-Out, Side-In/Bottom-Out, etc.) to ensure the housing fits perfectly into your existing infrastructure without expensive piping modifications.

Available Certifications & Compliance

Yes, K Filter can provide and support Third-Party Certification for all our filter housings. Because our products are used in high-pressure and critical-care environments (like medical and chemical processing), we ensure they meet the rigorous standards required for the Middle East, Europe, and Africa.

Here is how we handle third-party verification:

We manufacture according to international pressure vessel codes. Upon request, we can provide documentation for:

CE Marking (PED 2014/68/EU): Essential for the European market to ensure pressure equipment safety.

ASME Section VIII: The global standard for pressure vessel design, often required in the Middle East oil and gas sectors.

ISO 9001:2015: Certification for our quality management and manufacturing processes.

Material Traceability (EN 10204 3.1): We provide mill test reports to prove the chemical composition of our SUS304, SUS316L, and Carbon Steel.

2. Third-Party Inspection Agencies

We regularly work with world-renowned inspection bodies. You can request a third-party witness or “Thread/Stamp” from:

• SGS

• TÜV SÜD / TÜV Rheinland

• Bureau Veritas (BV)

• Intertek

3. Testing Protocols

Before any third-party certification is issued, every housing undergoes:

Hydrostatic Pressure Testing: Usually at 1.5× the design pressure.

Non-Destructive Testing (NDT): Including X-ray or Ultrasonic testing on weld joints.

Surface Roughness Testing: For sanitary/medical housings to ensure they are “stain-free” and polished to your exact Ra requirements.

K filter have manufacturing capability code 7 cartridge filter housings?

Yes, K Filter specifically manufactures housings compatible with Code 7 (226 O-ring/Bayonet) filter cartridges.

The Code 7 connection is the “gold standard” for critical filtration in the medical, pharmaceutical, and food & beverage industries because it provides a locked, high-security seal that prevents bypass under pressure.

Technical Specifications for Code 7 Housings

Our Code 7 housings are engineered to provide a perfect “Twist and Lock” fit for your cartridges:

Internal Socket: Precision-machined 226-style socket with a bayonet locking mechanism.

Sealing: Designed for double O-ring cartridges to ensure zero-leakage performance.

Cartridge Compatibility: Supports standard 10″, 20″, 30″, and 40″ lengths.

Materials: Available in SUS316L (highly recommended for Code 7 medical/chemical apps) or SUS304 stainless steel.

Surface Finish: Mirror-polished internal surfaces (Ra<0.4μm) to prevent bacterial growth and “staining.”

______________________________________________________________________________________________________________________________________________

Why use Code 7 for your project?

In markets like Europe and the Middle East, Code 7 is preferred over standard DOE (Double Open End) for several reasons:

Positive Locking: The bayonet tabs ensure the cartridge cannot “unseat” itself during pressure surges

Sanitary Integrity: The 226 O-ring design eliminates the need for bottom-spring plates, reducing “dead zones” where bacteria can hide.

High-Temp Reliability: Ideal for the high-temperature liquid filtration you mentioned, as the seal remains tight even as materials expand.

Does K Filter manufacture Code 7 (226) cartridge housings?

Yes. We specialize in high-precision Code 7 housings featuring a bayonet locking system. These are available in single and multi-cartridge configurations (up to 263 elements) for medical-grade and high-pressure chemical applications.

Are your Code 7 housings compatible with international cartridge brands?

Absolutely. Our 226/Code 7 sockets are manufactured to universal international standards, ensuring they are 100% compatible with cartridges from major global manufacturers.
