Hart Cooley 101arxl Low Pressure Damper Motor Spring Return

Product Description

The HART COOLEY 101arxl is a rectangular low pressure damper motor designed for zoning applications in light commercial and residential HVAC systems. It operates on an opposed blade cut-in configuration with spring return action, meaning the damper blade assembly returns to a default position on loss of signal or power. This unit is rated for systems handling up to 5 tons of cooling or heating capacity and is built to handle a maximum differential pressure of 0.5 inches w.c. HVAC technicians installing or servicing zoned duct systems will encounter this type of actuator as a core component in airflow control zones.

This damper motor is intended for rectangular duct applications in low pressure zoning systems rated at 5 tons and under. It is suited for residential and light commercial forced-air systems where zone control is managed through opposed blade dampers integrated directly into the ductwork. The cut-in design allows the motor to be installed into an existing duct section without requiring a full duct replacement. Systems with a maximum differential pressure at or below 0.5 inches w.c. are the correct application for this unit.

Key Features

• Opposed blade cut-in design allows installation into existing rectangular ductwork
• Spring return action restores damper to default position on power or signal loss
• Rated for systems 5 tons and under
• Maximum differential pressure rating of 0.5 inches w.c.
• Low pressure design suited for residential and light commercial zoning applications

Compatibility

Designed as an OEM-style replacement damper motor for rectangular low pressure zoning systems rated at 5 tons and under with a maximum differential pressure of 0.5 inches w.c.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low voltage zone control wiring and duct damper systems. Power down the air handler and de-energize all zone control circuits before beginning installation or replacement work. The cut-in mounting method requires precise duct penetration sizing to ensure an airtight fit and proper blade travel. Verify that system static pressure does not exceed the 0.5 inches w.c. differential rating before commissioning.
