If you currently have a 7.5 HP air compressor and the contacts on your pressure switch keep burning up, a starter is what is needed to fix the problem.
If you are using this starter on an air compressor, you will also need a pressure switch to control the starter. In this application the pressure switch controls the on and off of the starter depending on the pressure setting of the pressure switch.
There is a 30 day replacement warranty on this item that is ONLY available with proof of professional install.
