RETROZONE SD 9 inch DAMPERManufactured by RetroZone Inc, the Super Duty 9 inch round Damper is a commercial grade round damper at a price that competes with residential grade dampers.
We can sell this damper at this price because we are the manufacturer, there is NO MIDDLEMAN on this product! The quality of material is the best available and is backed up by a 5 year - Best In Industry Warranty. The industry leading Belimo LM24-3-T Power Open / Power Close 3 wire motor that drives this damper has 45 in-lb's of torque which is twice the amount of strength found in dampers similarly or even higher priced, yet uses far less power than spring return dampers.

Power use: The Belimo LMB 3 wire, power open-power close motor uses only 2 va of power, and only when in motion. Compare that to spring return motors that use a constant 8 to 10va when energized, and get to hot to even touch. The quality is beyond comparison to spring return dampers. One 40va 24vac transformer can power 20 or more SD dampers (compare to three or four spring return dampers). How? The industry renowned Belimo LMB motor uses power only when in motion, not continously, like a spring return, and never gets warm to the touch.
Works great on zone control systems or direct thermostat control, works great with almost any thermostat (see our damperdirect store for thermostats.)
One wire trigger works with direct thermostat control, no relays needed, so you get all the benefits of power open/power close control without the hassle.
This is the highest quality, most versatile damper on ebay. Even as a 3 wire damper, the versatile Belimo motor with 5 year warranty features a "one wire trigger" to work from a simple switch or thermostat, no relays needed. How? 24vac power is wired to terminals 1 and 2, and then switched power from a thermostat or switch to terminal 3 causes the damper to close. Remove power from terminal 3 and damper opens, its that easy. Request a "slave zone" diagram when ordering if connecting directly to a thermostat.
