Reverse Air (RA) Central Collector

        

C&W's Reverse Air Dust Collector is our most popular unit because of it's ruggedness, durability, user-friendliness, and proven-technology. Reverse Air dust collectors have multiple compartments that are configured very similar to the old style shaker units. Dirty air enters the bottom of the filter bags and dust is collected on the inside of the fabric. The compartments are cleaned in a sequence, set by adjustable timers.

Principles of Operation:

The Reverse Air design uses low-pressure air to collapse the bags. The bags clean as they are collapsed and re-inflated a number of times. The collected material then falls to the hopper below, where it is available to be recycled by the optional recycle system. This type of collector is more expensive than the shaker design, but the advantage of multiple compartments allows for higher dust concentrations and continuous use. As a compartment is cleaning the bags, the remaining compartments filter the air. The Reverse Air unit works well for material that is easily removed from filter media. The Reverse Air requires electricity and minimal compressed air.

The RA unit is also available as a package; the package includes: an RA-140 unit, Stationary Back-in shroud, and Ducting. Contact C&W at (800) 880-DUST for more information.

The largest RA Central C&W traditionally manufactures is 75,000 CFM, with the smallest offering 5000 CFM.

C&W's RA Series Collectors can be used on numerous dust applications, including but not limited to: Cement, Chalk, Clay, Coal, Coke, Fly Ash, Glass, Gold Ore, Lime, Gypsum, Paint Pigments, Sands, Salt, Slate, Soap, and Talc.
