Why is my Sullair 2200 not building full discharge pressure?

  If your Sullair Air Compressor isn't building full discharge pressure, consider these potential causes: The air demand might be too great, so check service lines for leaks or open valves. The air filter might be dirty, so inspect the filter indicator and replace the element if needed. A plugged inlet valve bleed orifice could also be the problem, so ensure the control line bleed orifice is not blocked. Additionally, the pressure regulator might be out of adjustment or defective, so adjust it or replace the diaphragm if necessary. Finally, a defective unload solenoid valve could be the issue, so check that it closes when energized, and replace it if defective.

Why won't my Sullair 2200 start?

  If your Sullair Air Compressor won't start, several factors could be the cause. First, check that the main disconnect switch is closed. Another possible cause is a blown line fuse, which would need to be replaced. Also, the motor starter overload might have tripped; try resetting it, and if the issue continues, inspect the motor starter contacts. Finally, low incoming line voltage could be the culprit, so check the voltage and consult your power company if it's too low.

What to do if my Sullair 2200 shuts down with air demand present?

  If your Sullair Air Compressor shuts down while there's still air demand, there are several potential reasons. It could be due to a loss of control voltage; try resetting it, and if the problem continues, ensure the line pressure doesn't exceed the compressor's maximum operating pressure. Low incoming voltage can also cause this issue, so consult your power company. Other possibilities include the separator needing maintenance (check the indicator under full load), a high pressure setting in the WS controller (reset it), a defective unload solenoid valve (repair if defective), or a defective blowdown valve (repair if defective). Restricted cooling air flow (clean the cooler and check ventilation), high ambient temperature (improve ventilation), low fluid level (add fluid), or a malfunction...
