How Does the Bag Filter Work

Bag Filter March 11, 2025 Multi Bag Filter Housing

A bag filter is a pressure filtration device primarily composed of a filter housing, filter cover, quick-opening mechanism, and a stainless steel reinforced mesh for filter bags.

Bag filters offer several advantages, including a well-designed structure, excellent sealing performance, high flow capacity, and easy operation. Notably, the risk of side leakage in the filter bag is minimal, ensuring precise filtration. Additionally, the quick replacement of filter bags reduces operating costs. The internal and external surfaces of the filter are treated with mechanical sandblasting and polishing, providing a smooth finish that is easy to clean.

Key Advantages

Minimal side leakage risk, ensuring high filtration quality.
Capable of handling higher operating pressures with low pressure loss, reducing operational costs and enhancing energy efficiency.
Filtration precision has improved significantly, reaching 0.5μm.
Large filtration capacity within a compact design, providing a high dirt-holding capacity.
Due to its unique design and working principle, filter bag replacement is quick and easy, and the system requires no cleaning, saving time and labor.
Filter bags are reusable after cleaning, reducing overall costs.
Versatile applications, with flexible installation options.

Main Applications
