Fluid Bed Dryer (FBD) Filter Bags are specialized filter components designed for use in fluidized bed dryers, where they serve the dual function of allowing air and vapor to escape while preventing fine powder particles from leaving the drying chamber. These filter bags are critical for maintaining process efficiency, product quality, and regulatory compliance, especially in pharmaceutical, nutraceutical, and chemical manufacturing.

Constructed from antistatic, non-woven, or woven synthetic fabrics like polyester, polypropylene, or PTFE, FBD filter bags are highly resistant to temperature, chemical exposure, and particle abrasion. They are typically sewn or welded to match specific dryer models and include reinforcements for durability and cleanroom-grade finishing to prevent contamination.
