Compressor capacitor

[Badger1bear]

Hi guys. How exact does a capacitor need to be for a compressor ? I am after two for a sip airmate

Can someone point me in the right direction online for a match or an equivalent rated one please

Mine failed, I just bought another on ebay. They are advertised as compressor capacitors. You've got the specs printed on your old one So I think you know all you need to know.

Make sure that the capacitor is of the right type for its role. A capacitor specified as a start cap. is not suitable for use as a run cap. Although a run cap. could be used as a start cap. Also, the voltages shown on your old ones should be taken as a minimum voltage. It make no difference if the replacement has a higher operating voltage. A few microfarads either way is unlikely to make a huge difference, for the start cap. but the tolerance on the run cap. is +/-5%.

I needed one for a pressure washer so I took the original to a local electronic shop JPG. They sold me one about half as big but assured me it was up to the job. £7 and it ran for a couple more years till the pump packed up. The motor is still in the shed with the capacitor and it still runs.
