Description

RETROZONE HD 8 inch Belimo LMB DAMPER
Manufactured by RetroZone Inc, this Heavy Duty  round Damper is a 3 wire round damper at a price that competes with residential spring return  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.  RetroZone sells this damper to A/C contractors and wholesalers all around the U.S. We will sell it directly to you in our Dampers Direct EBAY store.
Works with almost all zone control panels including Honeywell, Trol a Temp, Aprilaire,
Research Products, Robert Shaw, Jackson Controls, Ztec, Lennox, Waterfurnace, and almost all other brands of 24vac zone control panels.  Even if your zone panel  has just a two wire damper output, you can still use this superior, non spring return damper!
Also ties directly to a thermostat with out a relay, something most other 3 wire dampers  will not do.
Also see our Super Duty powered dampers, same Belimo motor, in our store damper direct.

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 too hot to even  touch.  The quality is beyond comparison to spring return dampers.  One 40va 24vac transformer can power 20 or more  dampers (compare to three or four spring return dampers).  How? The industry renowned Belimo LMB24 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.)
This is the  most versatile damper on ebay, along with our super duty SD dampers.  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.
