The bag filter housing is broadly used in various industries. In this blog, we will discuss what bag filter housing is, and its different types.

What is Bag Filter Housing?

The bag filter housing is a filtration system that uses a filter bag to remove impurities and contaminants from liquids. The filter bag is made of a porous material that allows the liquid to pass through while capturing the unwanted particles. The housing unit is designed to hold the filter bag and provide a secure and leak-proof seal.

The bag filter housing is available in different sizes, materials, and configurations, making them suitable for various applications. The most common materials used for bag filter housing are stainless steel, carbon steel, and plastic. The choice of material depends on the type of liquid being filtered, the temperature, and the pressure.

The sealing of bag filter housing is critical to ensure efficient filtration and prevent leakage. One common sealing method for bag filter housing is the compression seal. The compression seal involves compressing the filter bag against a sealing surface using a clamp or bolt and is commonly used in low-pressure applications.

Another is a rubber or silicone O-ring placed in a groove on the housing cover or body to create an O-ring seal, which is commonly used in high-pressure applications. This method involves using an O-ring to create a seal between the housing cover and the housing body.

Types of Bag Filter Housing

Single Bag Filter Housing

As the name suggests, single bag filter housing is designed to hold a single filter bag. It is the most common type of bag filter housing and is used in various industries, including food and beverage, pharmaceuticals, and water treatment. Single bag filter housing is available in different sizes, materials, and configurations, making them suitable for various applications.

The CST Classic Single Bag Housing is designed with a top-in and bottom-out configuration and features integral casting. Its compact structure and cost-effective performance make it a popular choice. The filter housing head is made with a combination of bolt fastening and integral casting, allowing it to withstand higher pressures and provide better sealing performance without any side leakage.

Top-in-Single-Bag-Filter-Housing

The CSC Classic Single Bag Housing is designed with a side-in flow direction, and the side-inlet pipe connection can be adjusted to different directions based on specific needs. The housing has a simple structure and is easy to clean internally. The CST Classic Single Bag Housing series features a lower resistance design, making it suitable for applications in the sanitary industry, as well as those involving high viscosity or low residue.

Multi-Bag Filter Housing

The bag filter housing is typically made from stainless steel and houses PP or PE filter bags or other filter elements. Pressure filtration is an innovative technology that supports bag filter housing, where a metal mesh basket holds up the filter bag inside the housing. The liquid enters through the inlet, passes through the filter bag, and exits through the outlet.

The Classic Multi Bag Filter Housing is designed to provide optimum filtration performance and offers filtration solutions for a wide range of fluid applications in the process industry. These filters are particularly useful for filtering large volumes of high viscosity liquids. The filter bag is supported by an internal cage within the filter housing.

Duplex Bag Filter Housing

The duplex bag filter housing is a highly efficient filtration system that is designed to provide continuous filtration without any downtime. This type of filter housing consists of two single bag filter housings that are connected in parallel, allowing one housing to be in operation while the other is being serviced. This ensures that the filtration process can continue uninterrupted, even during maintenance or replacement of the filter bags.

The duplex bag filter housing is particularly useful in applications where continuous filtration is critical, such as in the chemical and oil and gas industries. These industries rely on high-quality filtration systems to ensure the purity and quality of their products and to protect their equipment from damage caused by contaminants.

Plastic Bag Filter Housing

Plastic bag filter housings are a suitable option for filtering water or compatible non-hazardous chemicals. Brother Filtration produces plastic bag filter housings primarily using UPVC and PPR materials. Our plastic bag filter housings are available with different types of filter bags, just like our stainless steel housings.

The UPVC bag filter housing is a cost-effective and lightweight alternative to stainless steel housing with better chemical compatibility. Its plastic construction makes it rust-free and able to tolerate corrosive liquids and demanding operating conditions. The housing also offers better sealing performance and easy filter component replacement with rapid swing bolt closure.

UPVC-single-bag

The PPR bag filter housing is made of 100% Polypropylene Random Copolymer. This reinforced polypropylene housing is integrally injection-molded, eliminating the need for welding and preventing side leaks. It is easy to install and maintain, with strong resistance to acid and alkali making it suitable for chemical filtration. The PPR Bag Filter Housing can also operate in extreme conditions, with resistance to high temperature and pressure. Its softness and ease of molding also make it a great option.

Sanitary Bag Filter Housing

The sanitary bag filter housing is a specialized type of filtration system that is specifically designed to meet the strict hygienic requirements of the food and beverage industry and more. This type of filter housing is made of high-quality stainless steel, which is resistant to corrosion and is easy to clean. The smooth surface finish of the housing prevents the growth of bacteria and other microorganisms, ensuring that the filtration process is hygienic and sterile.

The sanitary bag filter housing is used in a variety of applications where the filtration process must be hygienic and sterile. For example, it is commonly used in the production of dairy products, juices, and other beverages, where the presence of contaminants can have a significant impact on the taste, quality, and safety of the final product.
