The single bag filter housing is designed to accommodate a single filter bag, making it ideal for any liquid filtration application. In this guide, we'll cover the basics of single bag filter housings, including structure, how it work, advantages, typical markets, and maintenance tips.
Structure
- Housing: Made of high-quality stainless steel or carbon steel, it is able to provide sufficient strength and corrosion resistance to withstand the challenges of internal pressure and harsh environments.
- Cover: Typically designed as a quick-opening structure for easy cleaning or replacement of the filter bag. The lid can be optionally equipped with a variety of sealing devices to ensure its tightness during the filtration process.
- Inlet and outlet: Usually located on the side or bottom of the filter, it is used to connect the piping system to achieve the inflow and exit of liquids.
- Support Filter Basket: Located inside the filter, it is used to support and hold the bag, preventing it from deforming or breaking under liquid pressure.
- Filter Bag: Placed in the basket, it is the main component of the filtration operation. The material and pore size of the bag can be selected according to the specific application requirements.

How It Works
The working principle of the bag filter housing is relatively simple and can be outlined using the following process:
When the liquid enters the filter, it first passes through the filter bag, which is supported by the filter basket. The bag has tiny pores that can trap contaminants and impurities of any size. As the liquid passes through, particles and harmful contaminants are trapped inside the bag, while the clean liquid is discharged through the outlet.
Technical Parameters

Advantages
- Compact Structure: The single bag filter housing is relatively small in size and occupies a small area, which is easy to install and maintain.
- High Filtration Efficiency: Efficient liquid filtration can be achieved by selecting the right material and filtration precision.
- Easy To Operate: Quick opening and closing structure, easy to clean and change the filter bag.
- Strong Corrosion Resistance: It has excellent corrosion resistance and is suitable for the filtration of a variety of corrosive liquids.
- High Pressure Capacity: It can withstand high working pressures to ensure the stability and safety of the filtration process.
- Low Maintenance Costs: Bag filter vessels require minimal maintenance and only require regular bag replacement. Ideal for small to medium-sized applications.
Typical Markets
- Water Treatment: Used in municipal water supply, industrial wastewater treatment, cooling water circulation and other fields.
- Food & Beverage: Used for clarification and sterilization filtration of juices, beverages, beer, etc.
- Pharmaceutical Industry: for sterilization and particulate filtration in pharmaceutical processes.
- Chemical Industry: Used for filtration, purification and separation of various chemical raw materials and products.
- Electronics Industry: Used for the filtration of liquids such as coolant and cleaning liquid.
Maintenance & Maintenance
- Periodic Inspections: Regularly inspect bags for integrity, cleanliness, and corrosion of baskets and filter vessels.
- Replace The Bag: Replace the bag regularly according to the actual need to maintain the filtration efficiency and accuracy.
- Cleaning The Housing: Regularly clean the dirt and sediment inside and outside the filter housing to ensure its proper functioning.
- Check The Seals: Regularly check the integrity and tightness of the seals, and replace them in time if damaged.
