Reverse Air Dust Collectors

1. Reverse Air central collectors are designed to collect dust from multiple points, such as mixer truck charging points or central mixers, cement weigh batchers, and silos.

2. Ducting is installed to different dust sources and proper hoods are used to pull dust into ducting and down into central collector.

3. Contaminated air enters the multi-compartment dust collector through the lower section and moves into the collector hopper.

4. Heavy dust particles settle out of the air stream and into the hopper bottom because of the reduction of air velocity.

5. Dust-laden air flows up through the inside of filter bags where dust particles are trapped. Filter bags allow clean air to pass through to clean air chamber.

6. Clean air flows through the fan and into the environment.

7. When reverse air door on top of unit opens to air from environment, flow of air is reversed through bags and cleaning cycle is initiated. This causes bags of one compartment to clean. The cleaning cycle is alternated between compartments.

8. Cleaning cycles of filter bags is automatically programmed by control panel. Time between cleaning cycles is controlled by one simple timer in control panel.

9. During bag cleaning cycle, air diverter door opens above one compartment, redirecting air flow, causing dust to be released from bag and fall into hopper below. The cycle rotates between compartments so each is cleaned in rotation.
