Draft Inducer Blowers
Regal Rexnord draft inducer blowers are purpose - designed, high - temperature, induced - draft and forced - draft fan assemblies that manage combustion airflow in residential, commercial, and industrial fuel - burning appliances — furnaces, boilers, water heaters, and unit heaters.Under the Fasco brand, our draft inducer line includes the precise replacement blowers for every major HVAC equipment brand(Carrier, Trane, Lennox, Rheem, and others), providing the exact motor speed, wheel diameter, mounting flange pattern, and electrical connection required for reliable, safe combustion venting.Service technicians and HVACR contractors specify Fasco draft inducers because an incorrect or generic draft blower can compromise combustion safety — improper draft can cause flame rollout, carbon monoxide production, or burner cycling failures that jeopardize building occupants.Fasco draft inducers are manufactured to the OEM’s original electrical and thermal specifications, with high - temperature motor windings, sealed ball bearings, and metal housing materials that survive the hot, sometimes acidic flue - gas environment.By maintaining the manufacturer - specified draft pressure and flow, Fasco draft inducers ensure clean, stable combustion and safe, code - compliant operation of gas - and oil - fired heating equipment.

Exact OEM Specifications
Fasco draft inducers are designed to duplicate the RPM, airflow, pressure, mounting, and electrical connection of the original equipment blower, ensuring drop -in replacement without field modification.
High - Temperature Motor Insulation & Bearings
Class B or F insulation systems and sealed ball bearings are rated for continuous operation in the 150°C to 200°C temperature environment of the flue - gas exhaust stream.
Corrosion - Resistant Metal Housing & Wheel
Galvanized or aluminized steel housings and stainless - steel wheels withstand the acidic condensate produced by high - efficiency(condensing) furnaces and boilers.
Complete Assembly with Gaskets & Hardware
Each draft inducer ships with the mounting gasket, screws, and wiring harness required for installation — no hunting for the correct gasket or hardware during a service call.
Universal - Fit Kits for Common Applications
For the most frequently replaced furnace and boiler models, Fasco offers universal draft inducer kits with multi - position mounting brackets and wiring adapters that cover numerous OEM part numbers with a single service - van stock item.
Agency Certifications for Safety Compliance
UL / CSA recognition as components for gas - fired appliance service, ensuring that the replacement blower maintains the safety certification of the heating equipment.
Why Correct Draft Inducer Replacement Is a Safety Critical Task
The draft inducer blower is one of the few HVAC components whose correct specification directly affects occupant safety.The blower must produce the precise negative or positive pressure specified by the appliance manufacturer to ensure proper combustion air delivery and complete venting of combustion products.A replacement blower with insufficient draft can cause flame rollout from the burner compartment, incomplete combustion that produces elevated carbon monoxide, and pilot or flame - proving failures that prevent the appliance from operating.A blower with excessive draft can over - fire the burner, increasing NOx production and potentially overheating the heat exchanger.Fasco’s strict adherence to OEM specifications eliminates these risks.Our engineering team maintains an extensive database of OEM appliance part number cross - references, ensuring that the Fasco draft inducer specified for each application matches the original’s performance exactly.For HVACR service contractors, specifying Fasco is a straightforward way to manage the liability and call - back risk associated with draft inducer replacement.
Draft Inducer Failure Symptoms & Diagnostics
A failing draft inducer typically produces audible warning signs — a loud hum, squealing bearings, or a rumbling vibration that progresses over weeks or months.Electrical symptoms include a motor that draws excessive current(overloaded) or fails to start.Combustion - related symptoms — the furnace or boiler failing to prove draft and locking out, or visible flame rollout — are the most serious and demand immediate service.Fasco supports the service trade with diagnostic guides that link draft - inducer failure symptoms to likely causes, enabling technicians to confirm the diagnosis and specify the correct replacement part on the first service visit.Fast, accurate diagnosis and same - day replacement — enabled by Fasco’s broad distributor stocking — restore heat and hot water to building occupants with the minimum disruption and service cost.
