Their existing push in cyclone with baghouse type after filter
was using a 50 hp main fan, a 30 hp material hndling fan (to the chip bin)
The system designed by AIR-TEK NW used a single 60 hp high efficiency airfoil type blower on the clean air side of a modern pulse jet baghouse to provide 16,000 cfm. The fan blowing up to the cyclone by the main blower.
The model FTP-144-10 pulse jet baghouse, airlocks, high efficiency

The total project cost $88,707. Rebates and incentives covered 38% to reduce Woodcastle's bill to $33,282.00. The rebate was based on cfm/kwh efficiency. The system proposed by AIR-TEK Northwest was at least 18% more efficient than the next closest vendor resulting in a higher rebate to the customer. Estimated yearly energy savings are $8,059 even with the increased volume.
