Recently acquired a Tuxing TXEDT032-1 compressor. Followed the break-in instructions. Filled my first tank a couple of months back. It seemed slower to fill that I anticipated. I don't recall the exact time that it took as I was filling a 9l tank from empty and I stopped and started a few times as it seemed the temp was getting higher than I anticipated. It eventually filled the tank to 4500psi. Well today I went to top off the tank, and after about 45min (compressor gauge was at 500psi) I decided to stop and do a deadhead test to see how long it would take to reach 4500 psi. After 30min. I stopped as the compressor gauge wouldn't go pass 500 psi again. Thinking I must have some issues somewhere. I sprayed some soapy water around the obvious areas and didn't see any obvious bubbles. Where should I focus on? Not really familiar with this compressor yet as I usually use my GX CS4.
How long should a deadhead test take on this compressor to reach 4500 psi?
