Field Controls 46275400 Venter

The Field Controls 46275400 Venter, also recognized in the field as the Model SWG-4HD power venter, is a heavy-duty side-wall venting solution designed for oil or gas-fired appliances. Operating at 115Vac and 3000 RPM, this unit features a 4-inch inlet and is engineered to provide positive mechanical draft where chimney venting is unavailable or impractical. As a veteran technician knows, the SWG series integrates a motor, blower wheel, and vent hood into a single compact housing, simplifying the installation of power venting systems. This specific model is built for high-demand residential or light commercial applications, ensuring consistent exhaust flow while maintaining tight pressure tolerances within the combustion chamber. When replacing a failed draft inducer or upgrading a system, the 46275400 provides the necessary induced draft to overcome external static pressure, ensuring safe burner operation and preventing the rollout of combustion gases.

Key Benefits

• Direct-Drive Motor: The 115-volt, 3000 RPM motor ensures consistent torque and reliable side-wall venting performance.
• Universal Compatibility: Fully interchangeable with the SWG-4HD, making it a drop-in replacement for existing Field Controls setups.
• Corrosion Resistance: Engineered with materials designed to withstand the acidic condensate often found in HVAC exhaust systems.
• Simplified Wiring: Designed to interface seamlessly with standard 24V or 120V control kits for automated burner sequencing.
• Internal Safety Switches: Built to accommodate a pressure switch to ensure the burner only fires when sufficient draft pressure is detected.

Common Questions

Can the SWG-4HD be used for both gas and oil furnaces?
Yes, this power venter is rated for both fuels, provided the installation adheres to the specific clearance and pipe sizing requirements for each fuel type.

Is the 46275400 a direct replacement for an older SWG-4?
The SWG-4HD (Heavy Duty) is the designated replacement and is built with a more robust motor assembly to handle higher duty cycles compared to standard units.

What size venting duct is required for this unit?
This model utilizes a 4-inch inlet; however, total vent run length and equivalent feet must be calculated based on the appliance's BTU output to ensure proper exhaust venting.
