Daikin-McQuay 059999804 Actuator

The Daikin-McQuay 059999804 Actuator is a dedicated 120V Spring Return Actuator engineered for precision control in commercial HVAC systems. Delivering 50 lb-in torque, this proportional damper actuator is designed to interface seamlessly with Daikin-McQuay air handling units and terminal equipment. It utilizes a modulating control signal to provide accurate positioning for air dampers or valves, ensuring optimal airflow management and system efficiency. The robust spring return safety mechanism guarantees a fail-safe position during power loss, protecting critical system components. Built for heavy-duty cycles, this direct-coupled actuator minimizes mechanical backlash and is built to withstand the rigors of industrial environments. Technicians will find the installation straightforward due to its standardized mounting footprint, making it a reliable choice for both field repairs and system upgrades where line voltage HVAC actuators are required.

• High-Torque Performance: Provides 50 lb-in for consistent movement of heavy dampers.
• Fail-Safe Operation: Mechanical spring return ensures the system returns to a safe state during power failure.
• Proportional Control: Allows for precise modulation rather than simple on/off operation.
• 120V Line Voltage: Eliminates the need for external step-down transformers in compatible cabinets.
• OEM Compatibility: Exact fit for specific McQuay and Daikin air handler configurations.
