• Extremely reliable.  Statistical life reliability exceeds 120,000 cycles at 90% reliability and 100% confidence with no decay in delivery torque over life of the actuator.
• Noise Level: Very quiet operation, typically ≦ 40dB at 3’

Our all metal gears and precision engineering get rid of the failure prone thin metal or plastic OEM gears from Honeywell. Our gears are twice as wide as the new “improved” Honeywell plastic-covered motors. See the gear comparison in the product photos.  We have also included photos of the motors that ours replace.
