speed control for electric motors
I am building a new house (2000 sf and probably 30000 cf with vaulted
ceilings) and want to install an exhaust fan in the attached garage. My idea is that it will get rid of welding smoke, saw dust etc.. but mainly I want it for cooling the house in the summer. Open the a window at opposite end of house, open window in the door between garage and turn on fan. I have no idea what CFM to get but was thinking about an 18" model rated at 3200 cfm. It uses a 1/3 hp motor. Can these be slowed down if to much air is moving. Can any motor be slowed with a speed control or are certain motors only designed for this. I guess I could put a smaller fan blade on to reduce flow. Thanks |
