Daikin-McQuay 065493801 Pressure Switch
The Daikin-McQuay 065493801 is a high-precision HVAC pressure control switch engineered for critical monitoring in light commercial and industrial environmental systems. As a genuine OEM Daikin replacement part, this adjustable pressure switch prevents compressor damage and ensures safe duct static levels by opening the electrical circuit when setpoints are breached. Designed for 120/240 VAC applications with a 1/4 HP rating, the 065493801 features a versatile pressure adjustment range from 0.05" to 5.0" W.C., making it ideal for managing high-limit safeties or fan proving tasks in complex air handling units.
Ruggedly constructed to withstand the rigors of continuous mechanical operation, this 065493801 pressure switch provides the reliability seasoned contractors expect from McQuay legacy engineering. It integrates seamlessly into existing control loops to protect against overheating and duct rupture, maintaining technical equilibrium within the system. Whether utilized for supply fan safety or return air static monitoring, this control switch is essential for professional-grade HVACR maintenance and system protection.
Key Benefits- Precise Setpoint Control: Features an adjustable range of 0.05" to 5.0" W.C. for tailored system protection.
- High Electrical Compatibility: Rated for 120/240 VAC at 1/4 HP to suit standard commercial control circuits.
- System Safeguard: Acts as a critical high-limit safety to prevent furnace overheating and structural duct damage.
- Authentic OEM Build: Ensures exact fit and performance characteristics as specified by Daikin-McQuay engineering.
What is the primary function of the 065493801 switch?
It serves as a safety control that monitors static pressure or airflow, tripping the circuit if levels exceed the manual or field-adjusted setpoint to prevent equipment failure.
Can this be used for both positive and negative pressure applications?
Yes, depending on the tubing configuration at the sensing ports, it can be utilized to monitor positive duct pressure or negative vacuum in return air paths.
Is this switch a manual or automatic reset?
Specifications for this series typically involve a manual reset for high-limit safety applications to ensure a technician inspects the system before restarting operation.
