SD 6″ Belimo 3 wire Motorized 24v round zone control damper

RetroZone™ SD 6″ DAMPER **Normally ships same day** Manufactured by RetroZone™, this Super Duty 6″ 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-lbs 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. RetroZone™ sells this damper to A/C contractors and wholesalers all around the U.S. We sell it directly to you in our damperdirect ebay store. FEATURES INCLUDE: 24vac powered, works with almost all zone control systems and thermostats (no matter what brand)Precision open and close motor adjustments allow fine tuning or air flowCan be modulated – damper blade will not move when de-energizedHeavy duty 22 gauge galvanized metal canHardware with bronze bushings, not plasticBelimo LM24-3-T brushless 3 wire power open / power close motorVery efficient: one 40va 24volt AC motor powers 20 or more dampersReinforcing beads for Super Duty strengthDuroZone commercial 1/2″ drive hardwareDurable 18 gauge blades bolted on – no cheap spot weldingFull DuroZone duct rated blade seals for almost 0% leakageUses only 2va of power for 90 second opening and closing time, compared to 8 to 10va continuous power on spring return dampersClutch button on face of motor allows easy rotation of blade for testingReversing switch on motor changes blade directionDirect drive quality – no cheap gears and springs on this damperWorks great with any brand zone control system or thermostatCan handle commercial system air pressures of 2″ or moreIndustry-leading 5 year warranty **FREE SHIPPING BY UPS GROUND TO THE CONTINENTAL US ONLY** POWER USE: The Belimo LMB24-3-T 3 wire, power open-power close motor uses only 2va of power, and only when in motion. Compare that to spring return motors that use a constant 8 to 10va when energized, and get too 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 24-3-T motor uses power only when in motion, not continuously, like a spring return, and never gets warm to the touch. WIRING TO A SWITCH OR THERMOSTAT: Works great on zone control systems or direct thermostat control, works great with almost any thermostat (see our damperdirect store for thermostats). 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.

Do not order if the 5 digit number ends in “R”, that means “right hand rotation” and the motor will not work for you, even if it looks identical. * You must either match the numbers, or visually the output shaft. Synchron made hundreds of motors that look the same from the motor side, but are not interchangeable, you must verify the 5 digit number. Thanks! * Cant find the right motor?
