The URD series of round motorized dampers are a double layered blade design with an integrated poron sealing gasket. The superior design insures long life and zero maintenance. URD dampers are easy to install, easy to wire up and come with a 5 year warranty. The URD damper is constructed of heavy 24 ga galvanized steel with factory rolled stiffening beads. The nylon bearings and ThermoTuff drive shafts insure smooth, quiet operation and provide a thermal barrier to the motor. The URD is designed to operate reliably at static pressures up to 1.5 in-WC. The UL listed MA-ND5 actuator is a 24 VAC three wire power open/power close type-rated at 18 in-lb of torque. It includes an integrated wiring terminal block and a NEMA 1 rated housing. The MA-ND5 motor features bright green and red LED's which correspond to the open and closed position of the blade. The motor also includes adjustable end stops for Min/Max blade position, that allows for field balancing of the full or minimum cfm flow, into a particular zone or area. The position LED's will illuminate regardless of the end stop positions.

For proper operation and efficient fuel consumption in oil, gas, and/or coal-fired heating appliances, draft must remain constant. When it is, combustion is more complete, fuels are utilized efficiently, and money is saved. Field Draft Controls maintain consistent draft by counteracting the negative forces caused by changes in temperature and barometric pressure, as well as the effects of wind.

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 0.02 - 0.08", this control is so sensitive that instrumentation should be used when adjusting the unit during installation.
