Compair Holman Zitair 125 - thermal cut out switch or switches?
I have the above compressor which I use to drive a lateral cutter which re opens connections in drains after they have been lined.
The compressor has run this tool with no problems until recently.
Now I can use the compressor and lateral cutter for around 20 mins then it switches itself off.
Wait 10 - 20 mins then I can re start it and use again for around the same amount of time and it will cut out again.
My question is does this compressor have a thermal cut out switch or switches that is causing this, if so where are they located and which one is most likely to be at fault.
I have these numbers from compressor

Any advice would be greatfuly recieved.
Michael, the "cool technology" reference is to the manufacturers of the compressor tank, www.pressure-vessels.co.uk/
And yes, it sure sounds as though your compressor is shutting down by an overload switch tripping.
We will have to rely on someone that is using or has worked on a Compair Holman Zitair 125 compressor for help here, Michael.

I have a Comair Kellog model B335UB sn V9J6186PFZI air compressor. It has a Baldor Industrial 5hp 3 Phase motor. It had been working fine for years. The compressor would not come on this morning.
I found that I could hold in the reset button on the Furnas Controller model PN XF-5-230 and the compressor will run but it will not shut off when it gets pressure built up.
I think it could be the Pressure switch but I do not know how to check. I would also like to know if you have the parts for this. Thanks Doyce
It has been my experience that when a compressor builds pressure to the normal cut out pressure level and doesn't stop, that it is the pressure switch that is at fault.
It is the pressure switch that senses the pressure in the compressor tank.
When that pressure falls to the preset level of that switch, it trips, and power flows to the motor.
As the motor runs, the pressure in the tank rises, until it reaches the cut out pressure level. At this point the pressure switch should trip off, cutting power to the motor.
In pressure continues to build in the tank as the pressure level bypasses the normal cut out, it signifies that the pressure switch has failed.
Replace it. Fast! It's dangerous to run an air compressor that will not shut off.
