Best Fasco Fans

For nearly a century, Fasco has been designing and manufacturing what has become the industry's most respected line of AC motors and blowers. Many of the new energy-efficient gas furnaces use induced draft blowers to control flue gas. All induced draft blowers incorporate some type of signaling device to alert the furnace that the induced draft blower is operating. Some use a sail switch in the exhaust air stream. Others utilize a centrifugal switch or electronic sensor built into the motor, and some use a static pressure tap in the blower housing. All blowers are intended to provide air flow prior to ignition. In today's furnace market, draft inducers are becoming a common replacement part. Since these furnaces are being designed with specific induced draft blowers, it is very important that replacements are installed using exact replacements. It is important that the replacements match the original blower for safety reasons. These blowers play an important part in controlling the availability of gas to the burners. Most blowers will employ either a centrifugal switch, electronic sensor or a vacuum tap to generate a signal to the gas valve that the induced draft blower is operating.
