Introduction

Filter housings are essential structural components that hold and seal filter elements such as pleated cartridges or capsule filters. They not only provide physical protection and mechanical support but also ensure that the filtration process operates under controlled pressure, temperature, and hygiene conditions.

Structure Overview

• Shell Body: Cylindrical chamber designed to contain one or multiple filter elements, made from stainless steel, polypropylene, or PVDF.
• Head and Closure: Designed for easy opening and secure sealing under pressure, often featuring clamp or bolt connections.
• Inlet/Outlet Ports: Configurable for flow direction (in-to-out or out-to-in) and compatible with sanitary fittings.
• Vent and Drain Valves: Allow air purge and complete drainage after filtration cycles.
• Support Plate / Cartridge Connection: Ensures proper mechanical alignment and sealing of filter cartridges.

Housing Materials

• Stainless Steel (304, 316L): Excellent corrosion resistance and high-pressure tolerance for industrial or hygienic use.
• Plastic (PP, PVDF, PVC): Lightweight, economical, and chemically compatible options for non-critical or corrosive applications.
• Sanitary Polished Finish: Smooth internal surface for pharmaceutical and food-grade processes.

Working Principle

Filter housings direct liquid or gas flow through the filter element while maintaining system integrity. Proper gasket and connection design prevent bypass leakage, ensuring that all fluid passes through the intended filtration media. Pressure gauges and vent ports assist in monitoring and control.

Uses and Advantages

1. Provides safe and sealed operation under specified pressure and temperature.
2. Protects filter elements from mechanical damage and external contamination.
3. Available in single-round or multi-round configurations (for 1 to 200 cartridges).
4. Support both liquid and gas filtration processes.
5. Designed for easy maintenance, cleaning, and cartridge replacement.

Application Industries

• Pharmaceutical & Biotechnology: Sterile filtration and process liquid handling.
• Food & Beverage: Filtration of wine, beer, dairy, syrup, and process water.
• Water Treatment: Industrial and municipal purification systems.
• Chemical & Electronics: Filtration of corrosive or high-purity fluids.

Key Features

1. High mechanical strength and durable construction.
2. Supports various filter element designs (DOE, SOE 222/226, or bayonet fittings).
3. Pressure rating typically from 0.6 MPa up to 1.6 MPa or more.
4. Configurable for horizontal or vertical installation.
5. Meets GMP, FDA, and sanitary design standards for clean applications.

Conclusion

Filter housings form the foundation of reliable filtration systems. Whether made from stainless steel or advanced plastics, their robust structure, hygienic design, and adaptability ensure safe and efficient filtration operations in diverse industries.
