The Air-Slide is designed to convey bulk powders from silos or storage compartments into a processing system. They provide a convenient and easily controllable method of conveying – they can incorporate bends and multiple discharge points if necessary.

The Air-Slide consists of a rectangular chamber separated by a permeable cloth. The chamber is inclined at a very slight angle (as low as 1.5°). Compressed air is injected into the lower chamber which then permeates through the media and "fluidises" the product. The product then behaves like a fluid and "flows" down the length of the chamber. The excess air is vented to a dust collector.
