Silicone dust caps for dust-tight powder transfer

When transferring powders in an industrial setting, creating a dust-tight seal is crucial to maintain cleanliness and prevent contamination during the charging or discharging process.

Ensure dust-tight transfer and containment

The Hanningfield Uni-Cap is a flexible silicone rubber seal designed for dust-tight transfer or containment of powders. The Uni-Cap can be adapted to various sizes and configurations, making it compatible with multiple types of process equipment, including mills, tablet presses, and vessels. The caps are available in several sizes, ranging from 2.5 inches to 16 inches in diameter, and are made from translucent FDA-compliant silicone. The Uni-Cap+ variant is fully transparent, offering excellent process visibility, which is particularly beneficial for monitoring powder flow and container fill levels. Both versions can be easily retrofitted to any process and come with stainless steel mounting rings for secure installation. The silicone used is platinum-cured, compliant with FDA standard 177.2600, and is also USP Class VI, TSE/BSE-free, ADI-free, and phthalates-free. For traceability, the manufacturing batch ID can be embossed onto the caps. Hanningfield Process Systems manufactures these caps in Great Britain.
