MIGHT CAN HELP. NOT AN I.R. EXPERT BUT KNOW A GOOD BIT ABOUT SCREW COMP. ARE YOU SHUTTING UNIT DOWN SUDDENLY WITH EMERGENCY STOP OR SOMETHING. SOME UNITS DO THIS MORE THAN OTHERS BECAUSE THE WAY THE VALVE CLOSES. BURPING OIL THROUGH THE INTAKE IS ALSO CAUSED BY SUDDEN STOP INSTEAD OF THE UNIT SLOWLY SHUTTING DOWN AND THE OIL IS RUNNING BACK SLOWLY. THE UNIT ACTUALLY TURNS BACKWARDS A LITTLE BIT. YOUR OIL SHOULD NOT COST THAT MUCH. YOU CAN CONTACT ME FOR PARTS AND PRICING ON THE OIL. YOU CAN SAVE ALOT OF MONEY WITH AFTERMARKET SERVICE PARTS AND OIL -THEYRE JUST AS GOOD AS OEM.I WOULDNT USE 30W OIL ! YOUR POOR AIR DELIVERY MAY BE AFFECTED BY WORN PARTS DUE TO LUBRICATION. HOW OLD IS UNIT? MODEL # ? CONTACT ME JBRIDGERS@CA-EQUIP.COM FOR INFO & PRICING. ME AND 1 TECH WOULD PROBABLY COME DOWN AND FIX IT FOR YOU FOR AN ALL EXPENSE TRIP FOR FREE. WE ARE IN NC AND DONT GET OUT ENOUGH.

I have a ssr ep 100 and the intellisys says no control power ive tryed to clear it but it wont


Probably have a bad High air temp. switch located in the end of the compressor air end. It has control power run thru the switch. If the switch opens on temp or just goes bad you lose control power which will come up on screen as control power loss. Replace HAT switch.

Coolant is come out of the air filiter on a rotary screw compressor ep 25


Does this unit have an intellysis controller. If so it also has a pressure transducer. The pressure transducer may need calibration. Also if this happen during freezing weather you may have condensate that froze in the sensor line. This would not allow the transducer or pressure switch to sense the correct line pressure which could cause oil to be blown out the air filter. If it does it during non freezing temps I would focus my attention on the minimum pressure check valve.

What is the solution when a ingersoll rand compressor model EP 25 is turn off and then this one made leave out the oil through of the inlet valve ?


Depends on the inlet valve of your air compressor, if it is a total closure type ( flat plate that closes completely) it is either a failure of the inlet valve seals or the control solenoid or other valve that controls the inlet valve.

If it uses a butterfly type inlet valve it is one of 2 things,,,, first if is spun slow after shut down and just oil was lost, the oil stop valve failed to close, if it spun fast and a combination of oil and air was discharged it was a stuck open air end discharge valve.

My rotary screw air compressor model SSREP100H


It's just too hot. Blow out the radiator weekly. There is an oil temp switch that might need replaced but the radiator is the most common problem with screw compressors. You can check the settings in the control panel, where you turn it on and off. It should be set for a high temp of 185°.
