RetroZone™ 12" Super Duty Spring Return Dampers, available in 24 volts or 120 volts, with optional end switch **Normally ships same day**

Had enough of residential grade spring return motor and damper failures?  Move up to the commercial grade Belimo TF Series 2-wire spring return dampers.  Service calls are expensive, only to find a cheap spring return damper at the source of your problems!

RetroZone™ Super Duty Series of Spring Return Dampers uses the industry renowned Belimo TF series spring return motors, mounted on our commercial grade steel can with DuroDyne Drive hardware - Best in the Business.

1/2 the power, but twice the torque!  How is that possible? Unlike cheap direct drive spring return motors, the Swiss engineered  Belimo TF series is a gear train motor to multiply torque from a smaller, more efficient motor.  And that's important, since a spring return motor pulls power continuously to overcome the spring, when energized.

• Works with any 24vac  zone control  system - replaces any two wire spring return damper

• Available in 24 or 120 volts, with optional end switches available 5 year factory warranty on the Belimo TF series motor

• Uses half the power of cheaper residential grade spring return dampers

• Higher airflow capabilities

• Muscular 22 inch pounds of torque at 5va, 2.5 watts

ORDERING:

LARGER DUCTS - 12” AND UP:
For duct sizes 12" and up, the Super Duty Spring Return is a must!  Larger round ducts carry far more airflow, and many residential grade, spring return 2 wire dampers are just not up to the task - blades can “flutter” in the air stream, and overall stresses on the springs and other parts, especially plastic parts, can lead to early failure.

SUPERIOR PRODUCT:
There is no finer, better built spring return damper on the market, at any price! There are no plastic parts, spot welds, or external springs to break. All RetroZone™ Duty Spring Return Dampers are backed by damperdirect, where dampers and zoning is our only business!
