Description
Overview
The Johnson Controls M9220-BGC-3 is a high-performance spring return direct coupled actuator engineered for reliable two-position damper control in commercial HVAC and building automation applications. Designed for direct shaft mounting without the need for crank arms or linkages, this actuator delivers consistent, fail-safe operation across a wide range of air handling and ventilation systems.
Key Features
- Dual voltage input: operates on 24 Vac or 24 Vdc power supply
- Two-position (on/off) control for straightforward open/close damper operation
- 177 lb-in (20 N·m) torque output for dependable actuation of large or high-resistance dampers
- Spring return fail-safe mechanism ensures the damper returns to its default position on power loss
- Power-on run time of 24–57 seconds for controlled, smooth damper travel
- 48″ (1219 mm) cable with wire leads for flexible installation in tight or remote mounting locations
- 2 SPDT auxiliary switches for end-of-travel position feedback and integration with building automation or control panels
- Direct coupled design mounts directly to damper shaft — no external linkage required
