    What to do if Sullair ES-6 Air Compressor will not build up full discharge pressure?
    • D
      david48Jul 27, 2025
      If your Sullair Air Compressor isn't reaching full discharge pressure: * Check service lines for leaks or open valves, as air demand might be too high. * Inspect the air filter and replace the element if it's dirty. * Adjust the pressure regulator according to the control adjustment instructions. * For a defective solenoid valve, a normally open solenoid must energize to load the compressor; check for proper operation.

    Why Sullair ES-6 Air Compressor shuts down with air demand present?
    • D
      Debbie EscobarJul 31, 2025
      Your Sullair Air Compressor might be shutting down due to several reasons: * Low incoming voltage, which may require consulting with your power company. * Excessive operating pressure, potentially caused by a defect in the pressure switch. * Restricted cooling air flow, necessitating cleaning the cooler and checking ventilation. * Ambient temperature being too high, so ensure sufficient ventilation. * Low fluid level, simply add more fluid. * Clogged filter, change the fluid filter element. * Thermal valve not functioning, replace the element. * Defective discharge temperature switch, check for a short or open circuit and correct the wiring.

      Eric PatelAug 4, 2025
      If your Sullair Air Compressor isn't starting, here's what you can check: * Ensure the main disconnect switch is closed. * Replace any blown line fuses. * Replace any blown control transformer fuses. * Reset the motor starter overloads. If the issue continues, inspect the motor starter contacts. * Check the incoming line voltage; if it's low, consult your power company.

    Why line pressure rises above cut-out pressure setting on pressure switch in Sullair ES-6 Air Compressor?
    • R
      Richard DonaldsonAug 9, 2025
      If the line pressure in your Sullair Air Compressor rises above the cut-out pressure setting, it could be due to: * A defective solenoid valve. * A leak in the control system causing loss of pressure signals; check for leaks. * A defective pressure switch; check that the diaphragm and contacts are not damaged and replace if necessary. * An inlet valve stuck open; inspect the inlet valve and ensure free operation.

    How to reduce excessive fluid consumption in Sullair Air Compressor?
    • J
      Joseph WalshAug 13, 2025
      To address excessive fluid consumption in your Sullair Air Compressor: * Remove the element cover and clean the orifice if the return line is clogged. * Change the separator element if it's damaged or not functioning properly. * Check all pipes, connections, and components for leaks in the lubrication system. * Drain and change the fluid if there's excess foaming. * Drain access if the fluid level is too high. * Replace the shaft seal if it has failed.

    Why pressure relief valve opens repeatedly in Sullair ES-6 Air Compressor?
    • S
      stephanie58Aug 17, 2025
      The pressure relief valve in your Sullair Air Compressor might be repeatedly opening because: * The compressor operating pressure is too high. * The pressure relief valve is defective; replace it.

    Why there is liquid water in compressed air lines of Sullair ES-6?
    • M
      michael92Aug 21, 2025
      Liquid water in your Sullair Air Compressor's compressed air lines is typically due to water vapor condensation from cooling and compression, which occurs naturally. Remove the water vapor from compressed air prior to distribution through the air system. Check operation of aftercooler and moisture separator. Install a compressed air dryer sized for the flow and dryness level required. Check all drain traps routinely to ensure their proper operation. Maintain them regularly.
