C2 Gasket Grounds Screens

March 21, 2012

The C2 gasket is a sanitary, conductive gasket capable of grounding screens to eliminate static that can build-up on some products. Screening problems result from particle-to-particle bonding (agglomeration) and by particles clinging to the screen mesh, both caused by excess static buildup. Finally, static build-up increases the risk of arcing which can cause dust ignition in extreme circumstances. By grounding a separator’s screens these issues can be minimized. Sweco has provided conductive elastomeric gaskets capable of grounding the screens to minimize static build-up. However, there has never been a gasket both conductive and made from FDA-approved components. The patented C2 Gasket (24-72 in. round) is a co-extruded product of FDA white silicone and conductive black silicone, producing a gasket that can be used in food and high static processes. The key is that the FDA white silicone element is the only portion exposed to product contact, while the black conductive component of the gasket makes contact with the frames and the outer lip of the screen tension ring (for Sweco STP and spot-welded screens only).
