Cosmos 1.5 HP micro compressor.

[Andrew TinsleyParticipant @andrewtinsley63637]

I have come by one of the above compressors, which are of Italian manufacture. It came without a pressure regulator on the output, which isn't too surprising, what does surprise me is that there is no pressure switch and no sign of one ever being fitted from new.

I am not a compressor expert, is this normal for a small compressor?

Some of these small compressors have an internal relief valve to set maximum pressure. Theoretically can be left to run continuously but in practice the motor duty cycle isn't up to that.

Just another way of trimming a bit more off the cost by not including a pressure switch in the box.

A 2kW compressor is not 'micro' , just what pressure , etc ,does it achieve.

1.1kW is closer, but from last post looks like limited to 40psi

You need to take up the term "Micro compressor" with Cosmos. Their description, not mine. It is rated at 120 psi has a 20 litre tank and a 1.5 Kw motor.

Thanks for that information Clive, it makes sense to me. The compressor unit is sealed (quote from blurb on the tank) and according to the same blurb on the tank it is " oil less". Despite the claim that it is a sealed unit, there appear to be enough bolts on show to strip it down!

Thanks gentlemen.

Andrew.
