C&W's BP Dust Collectors (or Bag-Pulse Jet) uses a brief burst of high-pressured air to clean the filter media (bags). The air flows from the outside to the inside of the filters. Dust is collected on the outside of the bags as the contaminated air passes through. This direction of air flow requires the use of cages inside the bags. As the pulse of air is directed through blow tubes, down the inside of the filters, the dust is blown off. It then falls and is collected for a short time in the hopper below, where it is available to be recycled by the optional recycle system. The entire cleaning process takes around one second. The largest BP Central Dust Collector C&W manufactures is 75,000 CFM, with the smallest offering 850 CFM. Pulse Jet technology is very reliable and effective, but it is also the most expensive among our fabric dust collectors. It requires electrical power, as well as clean, dry compressed air. C&W's BP Series Dust Collectors can be used on numerous dust applications, including but not limited to: Cement, Chalk, Clay, Coal, Coke, Fly Ash, Glass, Gold Ore, Grain, Gypsum, Paint Pigments, Sands, Salt, Slate, Soap, Talc, and Wood.
CARTRIDGE PULSE (CP) CENTRAL COLLECTOR
C&W's Cartridge Pulse Dust Collectors combine pulse-jet technology and our vertical cartridge filters to provide a highly effective, yet inexpensive solution for dust control. Cartridge Pulse units are similar in all respects to the Pulse Jet-Bag technology, except for the use of cartridges as the filter media, rather than bags. The use of cartridges increases the filtration area and reduces the number of filters needed. As a result, the dust collector is not as large and offers the most efficient filtration available at 99.99% efficiency. Other attributes of this collector are a space saving footprint, tool-less media exchange, and top loading filter media.

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 largest RA Central C&W 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.

Scientific Dust Collectors Manufactures a full line of Baghouse Dust Collectors to meet the needs of your specific operation. For over 28 years, SDC has provided customers with unmatched cleaning performance due to our superior cleaning system that employs a patented supersonic nozzle to clean the filters more effectively than any of our competitors.
TOP REMOVAL
Scientific Dust Collectors' Supersonic Pulse Jet Top Removal (SPJ-T) Collector is designed with a full walk-in plenum for easy bag access from the clean side. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. The SPJ Series is a heavy duty reverse pulse jet dust collector that operates continuously without requiring the process to be shut down for cleaning. The walk-in feature on the SPJ-T Series allows bag changeout from the clean side while not being exposed to the elements. Our high side baffled inlet with dropout section slows to less than 3000 FPM, which allows the large particles to simply fall out of the airstream into the hopper. Our bag spacing of three (3) inches between bags is the widest spacing in the industry. This reduces reentrainment of the dust. Our nozzle based cleaning system eliminates the venturi at the top of the bag/cage. This allows us to get over 300% more cleaning air into the bag than other generic baghouses.We gaurantee a stabilized pressure drop in our baghouse to be lower than 3.5"WC at full rated airflow.
BOTTOM REMOVAL COLLECTOR
Scientific Dust Collectors' Supersonic Pulse Jet Bottom Removal (SPJ-B) Collector is designed for low-profile applications where headroom is a factor. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. This design also has all the same benefits and features as our top bag access designs. The only difference is that the bags are accessed from the dirty air side of the baghouse.
LOW FLOW BOTTOM REMOVAL COLLECTOR
Scientific Dust Collectors' newest Supersonic Pulse Jet Low Flow Bottom Removal (SPJ-BL) Collector is economically designed for low-flow applications (less than 5,000CFM) and low static pressure (less than 14" SP). It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life.
BIN VENT COLLECTOR
Scientific Dust Collectors' Supersonic Pulse Jet Bin Vent(SPJ-BV) Collector is designed specifically for storage tanks, silos, work bins, and material receivers. It employs the patented supersonic nozzle cleaning system which allows the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. We can provide powered (with a fan) and non-powered (without a fan) bin vents. We can also customize the bottom flange to match customers' required opening.
HORIZONTAL COLLECTOR
Scientific Dust Collectors' Supersonic Pulse Jet Horizontal(SPJ-H) Collector is designed for low headroom applications, similar to the SPJ-B Collector. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. This special design uses horizontal bags that are accessed from the clean side of the unit. This is a specialty application unit where the dust is large and stringy, but there is a low headroom requirement.

SILO SAVER SYSTEMS (ANTI-OVERFILL SYSTEM)
Silos and dust collectors are vital to production in the concrete industry, and are costly to replace or repair, when damaged. Silo Saver SystemsTM (SSSTM) were developed to minimize guessing and eliminate human error when dealing with the 3 majors threats to silo and dust collectors. The 3 major threats are:
High Pressure: When blowing materials INTO the silo (filling) high pressure can become a problem. Usually pressure above 1.5 PSI can cause damage to the silo.
Overfilling: Overfilling a silo can damage or destroy it.
Broken Filter Media: Can pollute the air and cause a producer to receive a citation.
Anti-Overfill: Existing bin indicator monitors material level and signals when silo is full. Overfill light and horn are activated and pinch valve shuts line down after a preset time, avoiding serious damage or injury.
Air Flow Switch: Senses air flow through the silo collector and automatically turns the cleaning system on. When air flow ceases, system automatically turns off.
Pressure Sensor: Pressure above 1.5 psi can damage your silo and dust collector. Pressure Sensor detects high pressure and shuts the material flow down. Pressure Switch can also send a signal to turn collector on/off.
Broken Media Filter: Broken filters create maintenance disasters and can cause citations to be issued. Broken filter sensor uses microwave technology to detect damages and possible dangerous situations.
Smart-Clean: Is an automated cleaning system that manages when dust collector pulsing valves are activated (fired). Rather than pulsing on timed intervals, Smart-Clean increases the efficiency of the filtering by monitoring filter cake build up and keeping it within an optimal range. Key components include Smart-Clean Panel, Clean Out Connectors, and Pressure Hose.
