FAT Checks for a Pulse-Jet Baghouse Dust Collector
Define pass or fail checks for a pulse-jet baghouse FAT: verify bag count and fit, filter area, cleaning-air pressure range, and leak-tight assembly before shipment.
A buyer should decide before the factory acceptance test whether the pulse-jet baghouse will be accepted on documented inspection alone or only after witnessed checks of bag installation and cleaning-air function. That choice shapes the test agenda and the hold points.
For a chamber listed with 32 filter bags and 31 m² of filter area, ask the supplier to show how bag count and area will be verified at FAT, and whether these are reference values for the offered model or fixed requirements. Request that each bag seat and cage fit be checked, and that any damaged or misaligned bags be recorded as a fail item.
For cleaning air, the stated range of 0.5–0.7 MPa can anchor a functional check: confirm the test pressure, how pulse timing is demonstrated, and what evidence shows each valve operates. Ask whether the FAT includes a leak-tightness check of the housing and duct connections, and which instruments are calibrated.
Before requesting a quote, confirm with the supplier which checks are witnessed, the acceptance criteria and tolerances, the test pressure and air supply available at the factory, and how nonconformances are corrected and retested before shipment.
