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 change out 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 re-entrainment 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 guarantee a stabilized pressure drop in our baghouse to be lower than 3.5"WC at full rated airflow.
