Frame: Aluminium, Galvanization, Steel Spray Medium: Synthetic Material Production: methods Ultrasonic Thermal Bonding DAI/DE bag filter mainly be used on centralized ventilation system. It can be used as primary, medium and senior filter to protect inferior filter of system and itself. Bag air filter always adopt flat, diamond, honeycomb and V type bag. It adopts special process of ultrasonic heat sealing process which replaced the original process and avoid dust leakage on pinhole office as wellas enhance filter efficiency. The amount of small V type bag is determined by equipment's condition of using factory.
