I’ve had a CH 11 gallon 3.5 horse oilless compressor for 15+ years. It runs great and does every think I’ve ask it to do. I noticed some rust on the bottom of the tank so I know its days are numbered. I also have a 4 or 5 year old Kobalt 22 Gallon 1.3 HP oilless digital air compressor that was like brand new, because I never used it. It is a piece of ****. It is so loud you can’t stand to be around it and ran forever because of low CFM.
I do like the digital read out on the Kobalt, so I decided I will move my CH motor/pump over to the Kobalt tank and keep the digital pressure switch and double my air capacity.
After a little adapting I get it all hooked up and then I discover the problem. The CH was set for on at 90 and off at 120 PSI but the Kobalts range is on at 120 and off at 155.
In the little bit of testing I’ve done, the compressor seems to run great. It fills way faster and starts and stops at the proper ranges. The pipe that fills the compressor gets very hot but the motor remains cool. It does not sound like it is working any harder then it did on the other tank.
To resolve it I just need to change the pressure switch but I would really prefer to keep the digital read out.
My question is am I risking premature pump failure by working it at these higher ranges.
