Round dampers are power open/power close. Motor has red and green LED's that indicate damper position as well as when motor is moving and in what direction. Screw less connections are reliable and easy-to-use. Each motor allows adjustment of the minimum close position and the maximum open position. The gasketed edge on the blade furnishes a 99% shut off. The 1/2 in shaft is made of solid PVC so as to retard water condensation around the motor. Two bolts with neoprene nuts attach the damper blade to the 1/2 in shaft to insure reliable operation.
