Default Help Total Newbie to Air Compressors Etc.

Went out and bought a small 2hp air compressor and a hobby brush kit. Filled the compressor with oil and pluged it in. It says to turn the knob to lower the pressure but it still runs up to 110psi and shuts off. What am I doing wrong

Cheers

Can you post a link to the compressor you bought. Most compressors will pressurize their tank to the max (eg 150 psi) then regulate the air coming out to a lower pressure (eg 40 psi). Does your tank have one or two pressure gauges?

I'm guessing one of those gauges will read the PSI of the tank and one will read the regulated pressure coming out. What happens when you turn that black knob? Does the needle on one of the gauges move? If id does that needle will read the regulated pressure of the air coming out. The compressor pumping up the tank pressure to the max is normal. If it only pressurized the tank to your chosen regulated pressure then the motor would be coming on constantly. Hope that helps.

That second needle might not move until you use the air that is already in the hose. The black knob should have a + and - on it to show which way to turn it to reg. pressure.
