"Gas & Oil Vent Dampers, Draft Inducers, Duct Booster, Draft Control & Power Vent Kit"

GVD Series Vent Damper (Gas)


The Field Vent Damper works automatically to allow natural draft during appliance operation while preventing residual appliance heat and conditioned air from escaping during off cycles. It also prevents the infiltration of cold air during down drafts. It’s made of stainless steel and is available in 8 sizes, 4" through 10" and 12". GVD-Universal Wiring Kit
(sold separately)

Oil Vent Damper

Invest in your energy future with the Field Oil Vent Damper (OVD) system. It works automatically to save fuel, improve comfort, and keep the heat within the conditioned space. The Field OVD installs in the vent pipe after the draft control and before the chimney. It can increase Annual Fuel Utilization Efficiency (AFUE) by up to 2%.

Draft Inducer


Field Draft Inducers solve the drafting problems caused by short chimneys, undersized vent pipes and negative building pressures.

Draft Inducers are designed for easy installation in a wide variety of applications, including oil or gas-fired furnaces, water heaters, and boilers. For venting single or multiple appliances, use a control kit

Type RC Draft Control


Oil or Coal – Residential and Commercial
The Field RC is furnished as standard equipment on many leading brands of oil or coal-fired heating equipment. It is calibrated to allow for easy adjustment to the furnace or boiler manufacturer’s specifications. Designed for settings from .02" to .08", this control is so sensitive that instrumentation should be used when adjusting the unit during installation.

Air (Duct) Boosters


Field Air Boosters improve air flow and distribution of conditioned air to problem rooms in homes and businesses. They are mounted in ductwork and improve air flow by up to 1400 cfm, improving heating/cooling system efficiency and saving energy. There are nine models designed for round or square ducts up to 14" in diameter.
