Aeration conveyors (Air Slides) are used to gravity-convey powders by passing low-pressure air through a porous membrane media and into the bed of the material being handled.

You can handle a large variety of materials with aeration conveyors regardless of their abrasive nature or bulk density. The criteria are particle size, moisture content and temperature. Generally a product should have a particle distribution of 100% through a 20 mesh screen. Moisture content should be below 1% and temperature can not exceed 1200 degrees Fahrenheit [649˚ C].

The absence of moving parts and low power requirements make air gravity conveying the most economical way to convey fine materials over short or long distances.

DCL can perform a product compatibility test for you to determine the optimum conveying angles and aeration volumes for your application. We’ll need a minimum product amount of 2 cubic feet [0.07 m³] to conduct a proper test.

We offer a large selection of aeration conveyors from 6 inches [152 mm] wide up to 36 inches [914 mm] wide, with conveying capacities up to 1000 cubic feet per minute [28.3m³/min]. Conveyors also are available in a high top or low top design, offering you maximum flow rate or minimum headroom to best suit your application.

A choice of construction materials allows you to effectively handle all types of products – fine, abrasive and corrosive – and difficult dusty or sanitary applications.
