- Bag Filter Replacement
2.1 Change-out Pressure Differential: The recommended bag filter change-out pressure differential across the bag media is 0.10 MPa (15PSI). Continuing beyond this point will result not only in rapid flow rate reduction and contaminant unloading, but also increase the risk of filter rupture. The maximum differential pressure allowed is 0.23 MPa (35PSI).
2.2 Removal of Used Filter: During operation, the filter media may be embedded into perforated holes on the basket under excessive pressure, making it difficult to remove the bag filter. When this happens, DO NOT use excessive force to pull the bag, as it will break the ultrasonic welding line and detach the seal ring from the bag body. To safely remove the bag, shake the basket rapidly and then use a spine motion to separate the bag from the basket, slowly pull the use bag out.
