Engineered for differential pressure relief and dust-tight venting in powder handling systems, the SOSHH SF-Series Breathable Snap-In Connector replaces traditional clamped cloth sleeves. Featuring standard food-grade woven polyester with antistatic grid lines (BFM LM4 equivalent), high-air-permeability PP06, or heavy-duty PTFE-membrane needle felt (PE20), it snaps directly into grooved spigots in 30 seconds without tools. Certified to FDA 21 CFR 177.1630, it delivers continuous air venting (10-25 L/dm2/min) while containing ultra-fine powders in silos, sifters, and bulk bag filling lines.

Accumulating oversize debris, foreign matter, and agglomerates on screener discharge ports traditionally requires clumsy buckets, taped bags, or heavy clamped metal bins that leak dust and slow down cleanouts. SOSHH Snap-In Clear TPU Collection Blanking Socks provide a hygienic, 100% dust-tight, and liquid-tight collection receptacle. Manufactured from high-transparency, ether-based polyurethane (FDA 21 CFR 177.2600 compliant), these socks allow operators to monitor fill levels instantly without opening the process stream. The top snap-in cuff locks into standard SOSHH and industry-standard spigots in under 30 seconds without tools, providing a completely crevice-free transition that meets strict cGMP cleanroom standards.
Relieve Hopper Air Displacement While Capturing 99.9% of Sub-Micron Dust Rapid powder batching and gravity filling displace huge volumes of air inside hoppers, bins, and loss-in-weight feeders. When sealed with solid impermeable sleeves, this air displacement causes positive pressure surges that blow out gaskets, aerate powders, and cause erratic weighing errors on load cells. SOSHH Snap-In Breather Bags provide controlled, continuous pressure relief while retaining fine airborne particles down to 1 micron. Constructed from breathable polyester needle felt (FM1) and featuring an integrated snap-in seating band, these bags install tool-free in under 30 seconds directly into standard industry spigots. (或 standard SOSHH spigots The heavy-duty top loop handle allows effortless overhead suspension to prevent bag sagging during idle cycles.
High-performance anti-static PTFE snap-in flexible connector engineered for ATEX dust explosion zones and high-temperature powder handling systems. Featuring a conductive black fluoropolymer film with continuous 316 deg C (600 deg F) thermal stability and surface resistivity under 300,000 Ohms/sq, this tool-free snap-band sleeve provides an airtight, zero-leakage seal for vibratory sifters, fluid bed dryers, and pneumatic conveying. Designed as a direct drop-in replacement for standard spigot grooves and modular sanitary ducting, it guarantees universal chemical resistance (pH 0-14) with zero cross-contamination.
