Integrated Combo Filter Bags for Fluid Bed Processor Granulators

Skytech Ultrafab FBP Combo Bags are all-in-one integrated filter bag assemblies for Fluid Bed Processor (FBP) granulators and coaters used in pharmaceutical tablet and pellet manufacturing. The combo construction integrates both the retention screen basket and the upper dust capture filter bag into a single replaceable unit, eliminating the need for separate screen and bag assembly — simplifying GMP changeover, reducing contamination risk, and cutting changeover time on every product switch.

What Is an FBP Combo Bag?

A Fluid Bed Processor (FBP) Combo Bag is a single integrated assembly combining: (1) a precision-woven stainless steel or PP retention screen basket that retains granules within the processor bowl during fluidisation, and (2) an antistatic needle-punched felt filter bag mounted above the screen basket that captures the fine product dust entrained in the fluidising airstream. By combining both components into one replaceable unit, the combo bag enables single-step removal and replacement of all product-contact filtration components during batch changeover.

Features and Benefits

• Integrated Screen + Bag Assembly: Retention screen and dust filter bag combined into a single unit — eliminates the separate screen removal and bag installation steps of conventional split-component FBP filtration systems
• Antistatic Filter Bag: Upper dust capture bag fabricated from antistatic needle-punched polyester felt with conductive fibre for safe handling of flammable API powders and static-sensitive granules
• Precision Woven Screen: Lower retention screen woven from SS 316L wire mesh or PP monofilament with aperture sized to retain the granule size while passing fines — prevents granule loss into the fluidising airstream
• cGMP Construction: All materials FDA 21 CFR-compliant; no adhesives, staples, or hidden joints — full product-contact surface accessible for visual inspection and cleaning validation
• OEM-Compatible Dimensions: Combo assembly fabricated to the exact bowl diameter and retention ring dimensions of GEA, Glatt, Aeromatic, ACG, Shakti, and all major FBP OEM brands
• Single-Piece Changeover: Entire combo assembly removed and replaced in a single operation — reduces changeover time, eliminates misassembly errors, and minimises product cross-contamination risk

Technical Specifications

Applications

• Pharmaceutical Tablet Manufacturing: Wet and dry granule processing in FBP machines for tablet compression — combo bag ensures complete product retention during granulation and drying with simple cGMP changeover
• Pellet Coating: Pellet and bead coating operations in Wurster-type fluid bed processors where retention screen aperture must match pellet size range precisely
• API Granulation: Potent API granule processing where the integrated combo design minimises operator product exposure during bag changeover and reduces contamination transfer risk
• Nutraceutical Processing: Vitamin, supplement, and herbal extract granulation where batch changeover speed and contamination control are important for production efficiency
• Dry Powder Mixing: Powder blending in FBP equipment where the integrated screen and bag assembly protects the fan and exhaust system from fine powder carry-over

Why Choose Skytech Ultrafab for FBP Combo Bags?

• Single-Step Changeover: Integrated combo design reduces FBP changeover time — fewer parts to remove, fewer to install, fewer opportunities for assembly errors that cause batch failures
• Full cGMP Compliance: All-contact-material FDA certificates, dimensional inspection records, and antistatic test certificates supplied for pharmaceutical equipment qualification files
• OEM Cross-Reference: Combo assemblies fabricated to GEA, Glatt, Aeromatic, and all major FBP OEM dimensions — drop-in replacement without OEM part number restriction
• Reduced Cross-Contamination Risk: Single-unit replacement eliminates the open-bowl handling of separate screen and bag during changeover — critical for potent compound and multi-product facility operations
• Competitive vs OEM: Skytech FBP combo bags are significantly more economical than OEM spares while meeting or exceeding OEM dimensional and material specifications
