Filter Housings

Filter housings are essential components of industrial filtration systems, providing a secure and controlled environment for filter cartridges, filter bags, lenticular modules, and other filtration media.

Designed to withstand the operating conditions of the process, filter housings ensure that liquids, gases, and air streams pass through the filtration media in a safe and efficient manner. By directing the process fluid through the filter element, contaminants such as particles, microorganisms, and other unwanted substances can be effectively removed.

Filter housings are used across a wide range of industries, including water treatment, food and beverage production, pharmaceuticals, chemical processing, oil and gas, and general manufacturing. Depending on the application, filtration systems can be designed for particulate removal, sterile filtration, gas filtration, odour reduction, decolourisation, or the removal of oil contamination.

Techno Filter supplies a comprehensive range of filter housings, including cartridge filter housings, bag filter housings, lenticular filter housings, sanitary filter housings, and specialist housings for gas and air filtration applications.

How do filter housings work?

The operation of a filter housing is based on the controlled passage of a process fluid—whether liquid, gas, or air—through a filter element. The filter housing plays a crucial role in:

Ensuring even flow distribution across the filter element
Providing a leak-free seal
Protecting the filter element from damage
Safely containing process pressure and temperature fluctuations

Depending on the filter element and application, filtration takes place through one of two primary mechanisms:

Surface filtration: contaminants are retained on the surface of the filter media
Depth filtration: contaminants are captured within the structure of the filter media

By providing a controlled environment for the filtration process, filter housings help ensure reliable filtration performance, process safety, and efficient contaminant removal.

Lenticular filter housings utilise stacked depth filtration media and are particularly suitable for fine filtration, polishing filtration, and other critical process applications. Sanitary filter housings are designed to meet stringent hygienic requirements and are typically manufactured from stainless steel with smooth, cleanable surfaces suitable for CIP (Clean-in-Place) and SIP (Sterilise-in-Place) procedures.

When selecting a filter housing, several process parameters should be considered, including:

Operating temperature and pressure
Required flow rate and system capacity
Type of process medium (liquid, gas, or air)
Chemical compatibility
Contaminant concentration and particle size

In addition to these technical considerations, practical factors such as ease of maintenance, energy consumption, continuous versus batch operation, and waste reduction can also influence the selection of the most suitable filtration system.

Filter housings are used across a wide range of industries and process applications, providing a secure and reliable platform for liquid, gas, and air filtration.

Applications

Food and Beverage industry: Filtration of water, beer, wine, soft drinks, edible oils, and other food products. Sanitary and lenticular filter housings are commonly used where hygienic design and fine filtration are required.

Pharmaceutical and Biotechnology industry: Sterile filtration and critical process applications where product purity and process integrity are essential. Sanitary and lenticular filter housings help ensure compliance with stringent hygiene requirements.

Chemical processing: Filtration of chemicals, solvents, acids, alkalis, and other process fluids under controlled operating conditions.

Water treatment: Filtration of drinking water, process water, cooling water, and wastewater. Commonly used for pre-filtration ahead of reverse osmosis (RO) systems and other downstream treatment processes.

Oil and Gas industry: Removal of particulate contamination from liquids, fuels, hydrocarbons, completion fluids, and process gases. Protection of downstream equipment and critical process systems.

Gas and Air filtration: Filtration of compressed air, process gases, nitrogen, steam, and ventilation air. Removal of dust, oil aerosols, condensate, and other contaminants.

Power Generation and Energy Production: Applications within CHP systems, geothermal energy installations, utilities, and conventional power generation facilities.

Our portfolio includes:

Techno Filter filter housings are available in a range of materials, including stainless steel and high-performance plastics, making them suitable for a wide variety of process conditions and applications.

Lenticular filter housings are particularly well suited to critical filtration and polishing applications, offering high filtration efficiency and low product losses. Sanitary filter housings are specifically designed for applications with stringent hygiene requirements and feature smooth, cleanable surfaces suitable for CIP (Clean-in-Place) and SIP (Sterilise-in-Place) procedures.

Seals and Connections

Effective sealing is essential for the safe and reliable operation of any filter housing. Correct sealing prevents unfiltered fluid from bypassing the filter element, ensuring that the required filtration performance is maintained throughout the process.

Filter housings come with various connections and seals:

Inlet and outlet connections (flange, threaded, clamp)
Lid seals (O-rings, gaskets)
Internal seals for filter elements

The most suitable connection and sealing arrangement depends on the process conditions, hygiene requirements, and maintenance considerations of the application.
