Cartridge Silo Vents
Efficiency & Economy in a compact package
Designed to maximize efficiency while minimizing maintenance, Griffin’s Cartridge Silo Filter Vents are a compact solution for a wide-range of dust collection applications. Our ultra-efficient cartridges capture 99+% particulate emissions down to 1 micron from the silo while our powerful pulse jet system keeps the filters performing at their best. And without any internal moving parts, maintenance is kept to a minimum.
Like all of our dust collection systems, these units are built to be exceptionally rugged and ready to stand up to heavy-duty use. With a wide range of options, they'll bring you the flexibility to meet your application needs.
Save time with simpler filter change-outs
Simply loosen two swing-bolts, swing the roof up and away, loosen the hold-downs and replace the cartridges.
Flexible designs to meet the toughest conditions
Our standard Cartridge Silo Vents are designed with external pulse components (left), be we also manufacture units with internal components (right) when weather related corrosion is a factor. This means ultimate flexibility no matter where your silo is located.
Automatic Overfill Control System
The Griffin Overfill Control System, consisting of a closing valve, limit switch and control panel, completely automates silo filling and venting while preventing overfill and resulting damage. It is designed to operate on any pneumatic silo filling system with any number of fill pipes. If the high bin signal is clear when the trucker connects his hose to the fill pipe, the butterfly valve will open and the silo will accept material. When the high bin indicator is activated, an alarm will sound telling the trucker to stop his unloading operation. In 90 seconds the butterfly valve will close, sealing off the fill pipe and making it impossible for the trucker to continue pumping in material. The bags in the dust collection system will then automatically shake.
Options & Accessories
- Fans: available as required. Suitable for grade level or side mounting on collector.
- Hopper: Barrel hopper assembly, standard 60 degree slope with flanged discharge and support legs.
- Filter Media & Finishes: Griffin offers state-of-the-art filter media and finishes to ensure optimal efficiency for your collector.
- Automatic Overfill Control: Bin level indicator, pressure safety valve and alarm bell.

Bag Dump Stations
An Innovative Debagging Station to Save Time and Money for Users of Powder and Bulk Solids
If you use powders or bulk solids in your operation, Griffin Filters' Dustless Debagger can save you time and money while keeping your air clean. This self-contained unit is both a fast, efficient debagging station plus a complete dust control system.
Designed by our experienced engineers and backed by over 40 years of know-how in the air pollution field, it is ruggedly built for years of service. The Dustless Debagger is made of heavy duty welded construction. Small and compact in size, it is 99% plus efficient. There is a choice of three bag cleaning methods: manual shake, motorized shake, and pulse jet.The filter bags and cleaning mechanism are accessible from grade level. Filter bag replacement is fast and easy through a rear door opening. Blower fan is top mounted or, as an option, side-mounted.Because of its small size and relatively lightweight, the debagger can be easily transported. It is shipped as two components, with bags installed, for convenient field assembly.

Clean-A-Batch Systems
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:
- the silo filling
- weigh batching
- 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 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.
Duct Work Passages
(For Central Baghouse System)
Galvanized steel ductwork of 6" and 8" diameter designed for two silo pickup points and one weigh batcher; provides for distances of 15' horizontal and 60' vertical.
Hood Ductwork Package
(For Individual Collector System)
Easily assembled galvanized steel ductwork consisting of:
•Four 5' straight sections
•Two 90 deg. elbows
•Two adjustable nipples
•5'-0" flexhose
Dust Reclaim Systems

Batcher Filter Vents
Batcher Filter Vents are used to filter and release the displaced air caused by product filling the weigh hopper. The filtered product is then returned to the weigh hopper by gravity through the action of the shaking bags. Both Natural Vented and Blower Assisted models are available.
Silo Filter Vents
Industrial Silo Filter Vents are used to vent silos into which material is conveyed. As the material fills the silo, it displaces air, which must be vented without loss of product. Product collected on the filter bags is returned to the silo by shaking the bags after filling has been completed. Silo Filter Vents are available in two series:
- Natural Vented, where a low positive silo pressure is acceptable.
- Blower Assisted, where a negative silo pressure is desirable.
A Continuous Duty Vent (72-CS) is also available to provide continuous filtration through two individual compartments, one in the collecting mode while the other is being cleaned.
All options are electric, so no air supply is required.
Silo Filter Vent Operation
Natural Vents (IS & KS Models)
Displaced air from the silo filling operation is filtered
through the bags. After each truck is unloaded the bags must be cleaned. To clean the bags, shake them for approximately 60 seconds. (Mini-C10 control is optional)
Blower Assisted Vents (JS & LS Models)
Displaced air from the silo filling operation is filtered through the bags, while being assisted by a blower. After each truck is unloaded the bags must be cleaned. To clean the bags, turn the blower off and shake them for
approximately 60 seconds. (Mini-C8 control is optional)
Continuous Duty Vent (72 CS)
The baghouse is split into two 36 bag compartments so that one is in use at all times. A timer switches the diverter valve to the opposite side once every hour. The timer can be adjusted to switch sides more frequently if necessary. Each time the damper position is switched, the compartment taken off line is shaken for 60 seconds. (C6G2E control is included)

Automatic Overfill Control System
The Griffin Overfill Control System, consisting of a closing valve, limit switch and control panel, completely automates silo filling and venting while preventing overfill and resulting damage. It is designed to operate on any pneumatic silo filling system with any number of fill pipes. If the high bin signal is clear when the trucker connects his hose to the fill pipe, the butterfly valve will open and the silo will accept material. When the high bin indicator is activated, an alarm will sound telling the trucker to stop his unloading operation. In 90 seconds the butterfly valve will close, sealing off the fill pipe and making it impossible for the trucker to continue pumping in material. The bags in the dust collection system will then automatically shake.
