"Energy saving Equipment"
The main focus of ther project was to design a heavy duty, energy efficient system that would provide the customer with the added capacity that their growing company required. The customer was applying for energy efficiency rebates from the sate and their utility. The customer required minimal disruption in their production. The existing chip bim with cyclone was used to store all of the collected dust.

Their existing push in cyclone with baghouse type after filter was using a 50 hp main fan, a 30 hp material handling fan (to the chip bin) and
a 3 hp booster to run the plant at an ait volume of 11,000 cfm. With that, zones had to be gated and shifted to operate. There had been some problems with blockages in the airlocks.

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 blower, silencer and some special components were designed and built by LMC West of Riverbank, CA. This baghouse provides 2,400 spuare feet of filter for an air to cloth ratio of 6.67/1. It also features a
"walk-in-plenum" for easy inspection and service of the filters in any weather.

Much of the existing ductwork was left in place. Only areas where the line needed to be increased for the added air volume was replaced. New 24" diameter airlocks were used on the gaghouse discharge and the cylclone on the chip bin to eliminate blockages.

The project was began on Wednesday before Thanksgiving 2001, and was running by Sunday evening. The following week the old cyclone was removed.

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.
