Description
Overview
The GMA226.1U is a 120-volt, spring return damper actuator engineered for dependable 2-position control in commercial and residential HVAC applications. With a robust 62 lb-in torque output, this actuator delivers the driving force needed to reliably open and close dampers in air handling units, VAV systems, and ventilation assemblies. The integrated spring return mechanism ensures the damper automatically returns to its fail-safe position upon loss of power — a critical safety feature for smoke control, fresh air, and exhaust damper applications.
Key Features
- 120-volt AC power supply for compatibility with standard commercial HVAC control circuits
- Spring return operation provides automatic fail-safe positioning on power loss
- 2-position (on/off) control for straightforward open/close damper applications
- 62 lb-in torque output handles a wide range of damper sizes and blade configurations
- Dual end switches for position feedback and integration with building automation or control panels
- Compact, durable housing suitable for field installation in tight mechanical spaces
Application
The GMA226.1U is ideal for use in commercial air handling units, rooftop units, ventilation dampers, exhaust systems, and any application requiring positive 2-position damper control with end-switch feedback. The dual end switches allow the actuator to signal open and closed positions to a BAS, DDC controller, or relay panel, enabling sequence-of-operations verification and system interlock functions.
