How the equipment works
The documented airlock uses a geared rotor to transfer dust in pockets. Clearance and pocket filling affect its operation.
What to check for selection or replacement
Match YJD or YJD-B configuration, both flanges, bulk density and pressure differential.
FAQ · Is pocket displacement alone enough?
Also account for speed, fill, abrasion and leakage under differential pressure.
