Vacuum Loading Systems


Requiring quiet and reliable conveying of granules, regrind, or powders?  You have arrived at the right place.

Vacuum loading is the process of moving bulk dry materials (such as powders, regrind or granules), from place to place within a factory using suction. The material is transferred in a network of tubing from the pick-up point or source to the customers’ process.

Vacuum loading systems not only provide suitable transportation of bulk dry materials, but also lowers risks, increases cost effectiveness and maximises efficiency.
