It is a 50 litre and the brand is a John air. I can't find anything about it online and there is nothing to speak of in the 4page "manual". Only thing in the troubleshoot section is to replace the pressure valve. I wil contact the hardware store where I bought it and see if they can help me part wise.What's a 50 L? Your compressor doesn't have a brand name?
Direct drive relates to the motor and pumps drive arrangement but doesn't tell us if it is a rotary or a reciprocating pump.
When someone tells me something is not repairable I start talking to other people.
Yes it runs. I have it connected to my pneumatic hydraulic press. It loosing pressure and then started refilling and then suddenly made a deeper sound while refilling but didn't build pressure.Does the unit start bu not make pressure?
