Product Definition
The working principle of the glass fiber bag filter is:
Pre-filtration
The first filter bag effectively intercepts particles ≥5μm (such as hair and flocculent matter).
Deep capture
The glass fiber layer uses a dual mechanism of electrostatic adsorption and mechanical interception to precisely capture micron-sized particles.
Airflow optimization
The V-shaped bag structure effectively prevents airflow short-circuiting, ensuring consistent filtration across the entire area.
Application of Glass Fiber Bag Filter
Clean ventilation systems in the electronics, pharmaceutical, and food processing industries;
01

How to maintain and replace glass fiber bag filter?
Regularly monitor the inlet and outlet pressure differential (weekly inspection is recommended).
When the pressure differential reaches the replacement standard or the airflow is significantly weakened, the filter should be replaced promptly.
During replacement, carefully inspect the bag, support frame, and sealing strips to ensure they are intact.
Avoid direct contact with the filter media surface to prevent damage or fiber loss.
