Marvair 70080 Pressure Switch
The Marvair 70080 is a critical safety component engineered for Marvair HVAC units and wall-mounted air conditioners. This OEM high pressure switch is factory-calibrated to maintain system integrity by monitoring high-side refrigerant pressures. The Marvair 70080 pressure switch utilizes a precise 400 PSI open / 300 PSI close logic, ensuring that the compressor is immediately cut off during an overpressure event and automatically reset once pressures stabilize within a safe operating range. Designed for seamless integration into Marvair packaged systems, this switch provides the exact fit and electrical specifications required for HVAC high pressure protection in commercial and industrial environments. Utilizing a genuine Marvair 70080 replacement prevents terminal compatibility issues and ensures the safety circuit functions to original manufacturer specifications, protecting the compressor from catastrophic failure due to condenser coil blockages or fan motor malfunctions.
Key Benefits & Technical Specifications
- Precise Calibration: Fixed settings at 400 PSI cutout and 300 PSI cut-in for consistent high-side monitoring.
- OEM Compatibility: Specifically designed for Marvair wall-mount units and refrigeration equipment to ensure proper fitment.
- System Protection: Actively prevents compressor damage caused by excessive head pressure.
- Durable Construction: Built to withstand the high vibration and thermal cycling common in industrial HVACR applications.
- Direct Replacement: Simplifies installation for technicians by matching the original Marvair part number 70080 lead lengths and connection types.
Common Questions
What causes the Marvair 70080 to trip?
The most common causes for this high pressure switch to open include dirty condenser coils, a failing condenser fan motor, or non-condensables in the refrigeration system. If the system hits 400 PSI, the switch will break the control circuit.
Is the Marvair 70080 an automatic or manual reset switch?
This is an automatic reset pressure switch. It will automatically close the circuit and allow the system to resume operation once the high-side pressure drops back down to 300 PSI.
Can I use a universal pressure switch instead of the 70080?
While universal switches exist, using the genuine Marvair 70080 ensures the pressure settings and electrical ratings precisely match the requirements of your Marvair HVAC equipment, maintaining the safety listings of the unit.
