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.

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.
