Uni-Cap (dust-free transitions)

Uni-Cap is a fully cast hygienic dust-free transition. The material is a silicone that meets the requirements of the FDA.

The standard material is clear silicone, but special colors can be supplied subject to quantity and color request. A corresponding range of stainless steel support rings is also available, made from 316L stainless steel; various surface treatments can be provided.

Isolating Dust is an important problem in the process industry. Uni-Cap has been designed to help manufacturers meet the strict requirements required.

The Uni-Cap helps to isolate the dust and create a safer working environment, ensuring operators are fully protected during the transfer of powder processing.

By integrating the Uni-Cap with stainless steel support rings, the Uni-Cap system offers a very simple and cost-effective way to create a “closed system”.
