Question:
*
Why can't I use a regular universal motorized damper (HAC) to control the cold air coming from my combustion air duct?
*

This universal motorized 24Vac Fresh Air Control Damper , Series HAC , fastens to an air duct in-line to control the flow of air, partially or completely, depending on its mechanical setting.
This damper may be ordered with one motor, MS10A Actuator (replaces previous two motor model) or a Belimo actuator.


    CSA International Certified (up to 12"Ø).
Satisfaction guaranteed.

Features Include:
  • Easy to install in-line as part of standard air duct.
  • Durable, patented HMI  HOYME 'spring motor drive' with nylon bearings.
  • 26 ga. galv. steel from 4"Ø to 5"Ø.
    24 ga. galv. steel from 6"Ø to 9"Ø
    24 ga. galv. re-enforced steel from 10"Ø to 14"Ø
    22 ga. galv. re-enforced steel from 16"Ø to 18"Ø
    Other sizes and weight of steel upon request.
  • 8"Ø dampers and smaller are 8" in length
    9"Ø dampers are 9" in length
    10"Ø dampers are 10" in length
    11"Ø dampers and larger are 11" in length
  • 9"Ø dampers include a single reinforcement band
    10"Ø dampers and larger include two reinforcement bands
  • These dampers can be used for the new ventilation code which requires a designated exhaust fan, a centrally located switch marked 'VENTILATION' and a fresh air intake damper, all interconnected to the furnace circulation fan.
