Fluid Bed Dryer Filter Screen is used for holding product in fluid bed dryers and granulators while drying air passes up through a fine dutch-weave or sintered stainless screen. GMP is the reference cited for it on drawings, datasheets and purchase orders.
What GMP Means for Fluid Bed Dryer Filter Screen
The dimensions in the table below are supplied to suit GMP. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Fluid Bed Dryer Filter Screen Beyond the Standard
- Bowl size: Diameter matched to the dryer model and batch size.
- Micron rating: 25–100 µm so fines stay in the bed while air flows freely.
- Construction: Dutch weave on a support grid, or rigid five-layer sintered mesh welded into a ring.
When Fluid Bed Dryer Filter Screen Is Not the Right Choice
Not an exhaust filter — the bag or cartridge filter above the bed catches fines carried out with the air.
