A new range of explosion proof brakes designed for use in AC motors and transmission drives is now available from Specialised Air Motors & Transmission (SAMT) .

The VIS ATEX explosion proof brakes are an innovative line of modular flameproof spring applied disc brake units and designed to apply an independent brake unit to a standard B5 mount explosion proof motor or any other independent transmission drive.

An easy solution for making standard explosion proof brake motors these brakes are available in B5 flange in and B5 flange out (IEC 63 to 280) or NEMA if requested.

The new design will also reduce costs and lead times when ordering standard explosion proof brake motors as the cost of a standard explosion proof motor in addition to the new VIS brake is considerably lower than an explosion proof standard brake motor.
