JET III is a wholly new design in pulse JET dust collectors, offering the high collection efficiency by increasingly stringent environmental regulation, plus true economic is achieved by a new state of the art system designed to reduce maintenance, labor, parts and energy cost. Available in a full range of standard cloth areas, JET III also offers flexible sizing and efficient space saving installation. While sizing, access and housing construction of a dust collector are important, the critical features are the internals. Inside, JET III shows its superiority in these exclusive areas: Variation of the tube sheet / bag length can be tailored to a particular application and dust condition. This flexibility enables relatively small sized houses to be employed on large volume jobs, lowering capital cost. Smaller modules (19 to 521 sq. meter of cloth area) are square in plan and large volume modules (460 to 1195 sq. meter of cloth area) are rectangular. Both design features specially designed inlet connection for efficient gas flow and long filter bag life. Access to the unit is provided by an integral, full height, weather proof, walk in, clean air plenum. Where heat or other factors present special problems or where bags in excess of 144 inches long are used, manually operated, hinge roof doors are available.
