Medium Efficiency Non-Woven Pocket Filter

Non-woven pocket filter is primarily used for second- or third-stage medium efficiency filtration. They utilize high-loft, multi-layer composite non-woven filter media that offer greater strength than fiberglass; combined with a pocket-style design, ensures superior filtration performance, high dust-holding capacity, and stable airflow.

Key features

1. High-loft, multi-layer synthetic filter media that offers superior strength compared to fiberglass, excellent filtration efficiency, and high dust-holding capacity.

2. The filter pockets are constructed using ultrasonic welding to ensure full inflation and effectively prevent air leakage, bunching, or deformation.

3. Utilizes non-shedding, water-resistant filter media suitable for a wide range of operating environments.

4. Metal support strips are installed between the air filter pockets to enhance the stability of the frame.

5. Internal PP spacers ensure even airflow distribution and prevent the air filter from over-expanding under pressure.

Applications

Non-woven fabric bag air filter is widely used for medium-efficiency filtration in office buildings, shopping centres, hospitals, hotels, cleanrooms, fresh air systems, air handling units, and central air-conditioning systems. They effectively trap dust of medium particle size, airborne particulates, and some fine impurities, helping to protect downstream high-efficiency filters, thereby enhancing overall air purification performance and reducing system maintenance costs.
