Deca Air-Slide Flow Aid - Principles of Operation

The Airsweep Alternative - Deca Air-Slide

For severe flow problems the Deca AIR-SLIDE Flow-Aid Solution is the ultimate material flow problem solver.
Engineered to create and maintain material flow while also eliminating sticky & tacky build-up, arching, rat holes, and blockages.

The Deca Air-Slide Flow-Aid System can be used to promote and maintain material flow of dry, moist, hydroscopic, dense or entangled materials in any manufacturing or production process or environment (from pharmaceutical and food to pulp & paper, metals & minerals and chemical processing) in any type of container made from metal, plastic, fiberglass, concrete, or wood.

By strategically placing multiple Deca Air-Slide units throughout your container, blasts of air keep the material flowing in a downward direction.

On a timed cycle, a powerful blast of air pushes open the one moving part, the piston, releasing the air in a 360 degree pattern along the inner surface of the container wall, lifting and moving the material off the wall. This piston, along with the housing and all other components, are made of high grade machined steel, ensuring reliable and trouble-free performance for years to come.

The Deca Air-Slide should not be confused with the Airsweep® which is a registered trademark of Air Sweep Systems.

Example of PLC Controlled Air-Slide System

PLC Controlled Air-Slide System

Advantages of Controlling the Air-Slides with a PLC:

  • Highly customizable
  • Total control of firing and dwell times
  • Ability to control firing order and cycles

Controlling the Air-Slides in this way provides the ability to precisely control the amount of material that is consistently delivered to the feed system at the discharge of the container thereby lending itself to precise batching.

Open Top Outdoor Gypsum Hopper Showing Deca Air-Slide Sequential Firing

PLC Controlled Air-Slide System Video demonstrates the power and effective radius of each Air-Slide as the sequential firing is occurring. In this bin, the Air-Slides are mounted 4.5 ft upper row and 5.5 ft lower row from the top of the material. With each firing, you see the outer edge of the effective radius of the Air-Slides and the breakup of the material adhesion built up on the bin side wall, thus displacing the material downward to the auger system below.

Deca Air-Slide Flow Aid System Performance

The Deca Air-Slide Flow Aid System is successful because it creates and maintains material flow while also eliminating the following:

  • Costly down time for clearing out build-up or clogged bins, hoppers, silos, vessels, and bunkers
  • Sticky material build-up
  • Material adhesion to container wall
  • Bridging, arching, rat holes & clinging material
