To have the best filter bag filtration performance, it is essential to match it with an appropriate bag filter housing. And we will explain all the knowledge about bag filter housing and help you to make the right choice in selecting bag filter housing.

Single or Multi bag filter housing

According to containing a quantity of the filter bag, bag filter housings can be divided into 2 types. The single bag filter housing and multi-bag filter housing.

Just like their names, the single bag filter housing can only contain one bag filter inside. The multi-bag filter housing has higher filtration efficiency and larger dirt-holding capacity because it can hold more than one filter bag.

Stainless steel or plastic bag filter housing

Based on different raw materials of the bag filter housing, they can be classified as stainless steel bag filter housing and plastic bag filter housing. Stainless steel bag filter housings are generally made of 304L or 316L stainless steel.

When it comes to extreme operation conditions or strict sanitary requirements, it is vital to choose a stainless steel bag filter housing.

Plastic bag filter housing, as an economical choice, has a lower initial investment cost. It is suitable for water treatment and compatible with non-hazardous chemicals.

Top in or side in the bag filter housing

There are mainly two flow directions for a bag filter housing, which are the top inlet and side inlet. For top-in bag filter housing, liquid flows through the top design, which results in the least amount of unfiltered liquid remaining for simple bag replacement and optimal filter bag sealing.

For the side inlet bag filter housing, the side inlet pipe connection can be adapted to different directions according to specific needs. Housing has a simple structure and is easy to be cleaned inside.

Which applications are suitable for?

The top or side of the filter is where the liquid to be filtered enters the bag. A restrainer basket that manages the mechanical loads supports this filter bag. The filter bag holds the pollutants as the fluid travels through it. After that, the liquid exists in the filter housing through the bottom nozzle impurity-free.

The pressure upstream steadily rises throughout the filtration process until the bag is totally clogged. The installation must then be stopped, either manually or by using a valve to transfer to a different filter body. Open the cover, then swap out the filter bag.

The benefits of using a bag filter housing

From basic water to food products, paints and coatings, and various chemicals and solvents, filter bags are widely used in a variety of processes and industries. These applications often take place in a variety of ambient temperatures. According to the different needs and best filtration performance, we can select the proper bag filter housing.

Working conditions

Some industries filter liquids under high pressure and high temperature, which plastic housing may not withstand. Stainless steel housing is more durable and quite suitable for harder operation situations.

Additionally, when it comes to the pharmaceutical or food & beverage industry, a high sanitary level is required. High standard stainless steel housing can be applied to it, which is easier to clean and keep sterile.

Chemical compatibility

The type of filtered liquids should be also taken into consideration. The viscosity, corrosivity, and chemical components, all these characteristics all important factors when choosing an appropriate bag filter housing.

Costs and service life

In addition to the performance and characteristic factors of the filter housing itself, the cost is also one of the key factors affecting the selection. Generally speaking, stainless steel housing is more durable and able to withstand high temperatures and high pressure. But correspondingly, it will cost much higher initial investment costs.

The plastic bag filter housing is an economic alternative to stainless steel bag filter housing. It is particularly useful for large volumes of high viscosity liquids and corrosive liquids with lower costs.

Conclusion

A bag filter is a popular filtration method for various industries, to get the best filtration performance, we need to select the appropriate bag filter housing to match it.

There are plenty of different types, sizes, and materials of bag filter housing in the market, it is important to realize the real filtration needs and the characteristics of the different bag filter housing.

When it comes to industrial filtration, selecting the right bag filter housing configuration is crucial for achieving optimal performance and cost efficiency. With a range of options available, including single, multi-bag, and duplex configurations, it's essential to understand their unique features and benefits. Understanding the differences between these configurations will help you make an informed decision on which one best suits your filtration needs. Whether you are tackling large-scale filtration applications or require versatility and flexibility in your filtration system, we've got you covered. Discover the key considerations and advantages of each bag filter housing configuration, and empower your filtration process like never before.

Single Bag Filter Housings

Single bag filter housings are a popular choice for many filtration applications due to their simplicity and versatility. These housings are designed to hold a single bag filter, which can efficiently remove contaminants from liquid streams. Operating on a simple principle, the fluid enters the housing, flows through the single bag filter, and exits through the outlet port, leaving behind any particulates captured by the filter.

Benefits of Single Bag Filter Housings

One of the main benefits of single bag filter housings is their suitability for applications with varying flow rates. They can accommodate a wide range of flow capacities, making them adaptable to both small-scale and large-scale filtration needs. Additionally, single bag filter housings are relatively easy to install, operate, and maintain, which translates to convenience and cost savings.

Limitations of Single Bag Filter Housings

Nevertheless, it's important to note that the single bag configuration might have limitations in high-volume operations where a higher flow rate or continuous filtration is required. For applications with high flow rates or where downtime must be minimized, multi-bag or duplex housings might be more suitable options.

Applications

Single bag filter housings find their applications in various industries such as water treatment, food and beverage, pharmaceuticals, chemicals, and more.

Why choose a Single Bag Filter Housing?

Whether you need to remove debris, sediment, or larger particles from your process fluid, single bag filter housings provide a practical and efficient solution. Their versatility, low maintenance requirements, and ability to handle a range of flow rates make them a reliable choice for numerous filtration applications.

Multi-Bag Filter Housings

Multi-bag filter housings excel in applications where higher flow rates, larger particulate removal, or continuous filtration is required. These housings feature multiple chambers capable of holding multiple bag filters simultaneously, thereby offering increased surface area for filtration. With their ability to handle larger volumes of fluid, multi-bag filter housings are well-suited for industrial processes that demand efficient and continuous filtration.

In operation, the fluid enters the multi-bag housing and is distributed evenly among the individual bag filters. As the fluid passes through the filters, contaminants are trapped within the bags, leaving the filtrate to exit through the outlet port. This design allows for efficient removal of finer particles and greater dirt-holding capacity, ensuring longer intervals between filter change-outs and reduced downtime.

Benefits of Multi-Bag Housings

The benefits of multi-bag filter housings extend beyond their higher filtration capacity. Their larger size means fewer change-outs compared to single bag housings when dealing with high volumes of fluid. Moreover, multi-bag housings often come equipped with user-friendly features, such as quick-release mechanisms, that simplify filter replacement and maintenance procedures.
