MODULATING AUTOMATIC ROUND DAMPERS
The “MARD” is a single blade, round motorized damper, with gasketed seals for a tight shut off. The 24 volt power open-power closed damper motor drives the damper blade open or closed based upon the demands of any type of single pole-double throw and center off switch control. It can also be used with the SPC control to maintain a set range of static pressure in the duct system. The “MARD” will modulate open when the duct pressure rises above null (off) setting and modulates closed when the duct pressure falls below the null setting. The “MARD” can also be controlled individually by a TRT thermostat or Mastertrol panel to just open and close. Also available in non-stock, rectangular sizes (MOBD). Please contact your R.E. Michel sales representative or local branch for more information.
