Field Controls 46395401 Venter

The Field Controls 46395401 Model SWG-4HDS is a heavy-duty stainless steel power venter engineered for side-wall venting of oil or gas-fired heating equipment. Operating at 115Vac and 3000 RPM, this 4-inch inlet motor kit is designed to maintain consistent negative pressure in the vent pipe, overcoming chimney draft issues or allowing for installations where traditional vertical chimneys are impractical. This HVAC power venter motor features a corrosion-resistant housing, making it ideal for high-efficiency condensing boilers and furnaces where acidic flue gases are present. The centrifugal wheel design ensures optimal flue gas extraction, and the unit integrates seamlessly with Field Controls draft controls and pressure switches to ensure safe, code-compliant operation. For contractors, the SWG-4HDS provides a reliable solution for mechanical draft induction, supporting long vent runs while ensuring fuel combustion remains stable and efficient throughout the heating cycle.

• Corrosion Resistance: High-grade stainless steel construction prevents premature failure caused by acidic condensate in flue gases.
• Optimized Performance: The 3000 RPM high-speed motor provides the necessary static pressure for challenging side-wall venting configurations.
• Universal Compatibility: Designed for use with 4-inch vent piping on a wide range of residential and light commercial oil or gas appliances.
• Safety Integration: Easily interfaces with safety interlocks to prevent burner ignition if proper draft is not established.

Common Questions

Can this unit be used with high-efficiency condensing furnaces?
Yes, the stainless steel construction of the SWG-4HDS is specifically designed to handle the corrosive nature of condensate found in high-efficiency gas and oil applications.

What is the proper procedure for setting the draft on this power venter?
Technicians should use a manometer to measure the overfire draft and adjust the internal damper or motor speed controls to meet the appliance manufacturer’s specified draft requirements.

Will the SWG-4HDS solve backdrafting issues in basement installations?
It is designed to create a mechanical draft that pulls flue gases through the side wall, effectively neutralizing backdrafting caused by negative house pressure or poor chimney design.
