The M7215 Damper Motors from the company provide 25 lb-in. torque with spring return and 2-10 Vdc modulating control of economizer systems, ventilation dampers and combustion air dampers used in residential or commercial HVAC equipment. The M7215 Damper Motors provide modulating control of economizer dampers from a 2-10 Vdc controller, quiet, high efficiency drive motor, High impact glass-fiber reinforced plastic case is rugged, lightweight and corrosion resistant. This motor provides 2-10 Vdc output signal proportional to the shaft position.

M436A/M836A, B Damper Motors are spring return (SR) motors used for residential and light commercial applications in Series 40 and Series 80 circuits. Some features of this damper motor are they provide two-position zone control, used to operate outdoor air dampers for combustion or makeup air, changeover dampers for heating and cooling systems, minimum position dampers for ventilation and similar applications. The damper motors M436 need 120 or 240 Vac, 60 Hz power while the M836 Damper Motors require 24 Vac, 60 Hz power. The models are supplied with a case and cover and have spring returns motor to start position in event of power interruption or failure. M436A and M836A come equipped with thermal breaker for overload protection during lifting stroke or when motor stalls.
