Capture the dust from the air in your shop. The G9956 Heavy-Duty Double Air Filter is designed to capture dust from ambient air in a woodworking shop for a short time after cutting or sanding operations. Set the duration and speed with the remote control from as far away as 45 feet, then hold on as the fan spools up to draw a massive 1400 CFM through the 5-micron primary filter and then through the 1-micron secondary filter. The air is drawn in through the filter by a 9-1/2" centrifugal fan or "squirrel cage" impeller and filtered before it returns to the workspace. The five fan speed options are 800, 900, 1000, 1100, or 1200 RPM. The G9956 will recirculate the volume of air in a 20' x 20' x 8' room approximately 26 times in one hour. We recommend that the volume of air in your room be recirculated 6-8 times an hour for the best filtering effect. The G9956 manual was written by our U.S.-based Technical Documentation Department and is packed with useful information. The complete and easy-to-read manual makes it easier to assemble and maintain your filter. G9956 parts may be available online and shipped from the Grizzly parts warehouse in Springfield, MO. Made in an ISO 9001 factory CSA certified
