Precision Particle Retention in Industrial Vacuum Filtration Systems

Skytech Ultrafab Vacuum Filter Bags are designed for industrial vacuum filtration systems used in pharmaceutical manufacturing, chemical processing, battery electrode production, and environmental remediation. Available in woven and non-woven polypropylene, polyester, nylon, and PTFE fabrics with micron ratings from 1 to 200 µm, these bags provide accurate particle retention under vacuum conditions without media migration or structural collapse. Custom fabricated to fit rotary drum vacuum filters, horizontal vacuum belt filters, and vacuum leaf filter vessels.

What Are Vacuum Filter Bags?

Vacuum filter bags are filter media elements designed for filtration systems where liquid is drawn through the media by negative pressure (vacuum) rather than being pushed through by pump pressure. The vacuum creates a differential pressure across the filter media that drives filtration while pulling the bag tightly against its support structure. The bag must maintain its shape and filtration integrity under vacuum conditions, resist collapse, and provide precise particle retention across many operating cycles.

Features and Benefits

• Vacuum-Rated Construction: Reinforced media and seam construction designed to maintain shape and integrity under continuous vacuum suction — preventing media collapse or distortion that would cause bypass
• Precise Micron Retention: Woven monofilament and needle-felt options from 1 µm to 200 µm provide accurate particle retention across the full range of vacuum filtration applications
• Anti-Collapse Reinforcement: Internal structural support rings or stiffening inserts prevent vacuum-induced bag collapse in tall vertical vacuum filter elements
• Multiple Material Options: Polypropylene, polyester, nylon, and PTFE fabrics cover the full pH range and temperature requirements of pharmaceutical, chemical, and environmental vacuum filtration
• Custom Vessel Fit: Bags manufactured to the exact dimensions of rotary drum vacuum filters, horizontal vacuum belt filters, and vacuum leaf filter vessels across all OEM designs
• Food and Pharma Grade: FDA 21 CFR-compliant PP and PES options for vacuum filtration in food processing and pharmaceutical manufacturing in cGMP environments
