What causes repeated opening of the pressure relief valve in Sullair Air Compressor?
The pressure relief valve in your Sullair Air Compressor may be opening repeatedly due to: * A defective pressure relief valve. If this is the case, replace it. * The unload pressure being set too high. Adjust the pressure switch per the UNLOAD PRESSURE SETTING. * Failure of the unload solenoid valve. Replace or repair the solenoid valve.
How to fix excessive fluid consumption in Sullair Air Compressor?
Excessive fluid consumption in your Sullair Air Compressor can be caused by: * A clogged return tube or orifice. Clean the orifice or strainer. * A damaged or malfunctioning separator element. Replace the separator. * A leak in the lubrication system. Inspect all pipes, connections, and components. * Excess fluid foaming. Drain and change the fluid. * Fluid level being too high. Drain and change the fluid. * Operating pressure lower than rated pressure. Increase compressor operating pressure. * Fluid level is too high. Drain excess fluid.
Why Sullair E900H Air Compressor will not build full discharge pressure?
If your Sullair Air Compressor isn't building full discharge pressure, here are some potential reasons: * Air demand is too great. Check service lines for leaks or open valves. * The air filter is dirty. Check the filter indicator and inspect or change the element if needed. * The inlet valve bleed orifice is plugged. Ensure the control line bleed orifice is not plugged. * The pressure regulator is out of adjustment. Adjust the regulator according to the control adjustment instructions. * The pressure regulator is defective. Check the diaphragm and replace it if necessary. * Check valve operation. Replace the coil or the complete valve if defective. * Improper unloading with an excessive pressure build-up causing relief valve to open. Check for a leak in the control system c...
Why Sullair E900H will not start?
Your Sullair Air Compressor might not start due to several reasons: * The main disconnect switch might be open, in which case you should close the switch. * A line fuse might be blown, requiring you to replace it. * The motor starter overload might be tripped; try resetting it. If the issue continues, inspect the motor starter contacts. * There might be low incoming line voltage. Check the voltage, and if it's low, contact your power company. * An incorrect phase order could be tripping the phase monitor. To resolve this, switch any two phases of incoming power and reset the monitor. * The ground fault protector might be tripped. Look for shorts or open circuits in the control circuit, repair them, and reset the protector. If the problem persists, the ground fault protector ma...
What to do if Sullair E900H shuts down with air demand present?
If your Sullair Air Compressor shuts down while there is still a demand for air, consider the following potential causes: * A loss of control voltage. Check the incoming power connections and reset the monitor. * Low incoming line voltage. Check control fuses and wiring, and consult your power company. * The compressor discharge temperature switch is open. This could be due to restricted cooling airflow; clean the cooler and ensure proper ventilation. * High ambient temperature. Ensure sufficient ventilation. * Low fluid level. Add fluid. * Clogged filter. Change the fluid filter element. * Thermal valve not functioning properly. Replace the element. * Defective discharge temperature switch. Check for a short or open circuit; if none, replace the switch. * Cooling fan op...
What to do about liquid water in compressed air lines of Sullair E900H Air Compressor?
If you find liquid water in the compressed air lines of your Sullair Air Compressor: * Check for a plugged separator differential. * Clean and service the strainer located in the line off the bottom of the water separator if it's plugged. * 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. Ensure you check all drain traps routinely to ensure their proper operation and maintain them regularly. * Ensure the drain solenoid valve opens and closes as signaled by the timer if it is defective. * Check and adjust the drain interval and drain time if the drain settings are improper. Note that high humidity conditions r...
