Clean-A-Batch Systems provide turnkey dust collection solutions for concrete batch plants.

Griffin Filters offers numerous models within the Clean-A-Batch system capable of providing dust free operation for your batch plant. Whether your needs are for Transit Mix (dry), Central Mix (wet) or Combination; whether it is high or low production; a stationary or portable plant; we have the equipment to give you the assurance of meeting today's environmental standards.

There are three steps during the batching operation where dust must be controlled. These three are:

1. the silo filling
2. weigh batching
3. and truck loading

Griffin offers two alternatives for your equipment selection. There can be a single Central Baghouse which draws the dust from each of these points, or smaller Individual Dust Collectors located at the points of dust generation.

Your local Griffin dealer or our factory engineers are available to help you decide upon the most effective and economical approach for your particular plant. Either way, these systems are capable of dust control far exceeding the 99% efficiency required for clean operations.

Clean-A-Batch Systems Options

Clean-A-Batch Baghouses

Shaker Model Baghouses are intended for intermittent batching, generally under 20 loads per hour, where there is an interval of 30 seconds or more allowing the bags to be shaken free of dust after several loads. Only electrical energy required.

Jet-Aire Baghouses are used for high production continuous batching. Requires compressed air and electrical hook-up for continuous bag cleaning.

All Griffin Clean-A-Batch Baghouses feature as standard:

• 12 gauge all welded steel construction designed for -20" W.G.
• Polyester bags
• Structural steel for 4'0" clearance
• Pyramidal hoppers with manual rotary gate.

Suction Hoods

Drive Through Hoods

The Dust Hugger, Model TH-90, by Griffin Filters controls dust with both ease and economy.

Dust control begins with the hood. The hood should capture the greatest amount of dust with minimum energy. An effective hood must allow easy access for both front load and rear load trucks, whether they back in or drive through. The Dust Hugger accomplishes all this while enabling the batch operator superb visibility for proper truck positioning.

As the Dust Hugger hood captures the dust, it is the downstream dust collector that contains the dust while allowing clean air to pass through the fan to the atmosphere. We offer several models of Dust Collectors specifically for concrete batch plants. All are field proven to give years of reliable service.

Back-In Truck Hoods (Models BID)

An economical dust hood for batcher plants, Griffin's stationary Back-In Truck Hoods (13-BID) are designed for back-in loading.  The top section is an all steel construction with rubber sides and front flap.
