Speedaire 4b23415 min to build to 135psi

My 4b234d 2hp 30 gallon horizontal compressor takes 15 min to build pressure to 135 psi. Is this normal? It can be hooked to 110 or 220 volt and currently is 110 hookup. Is the pump bad(wouldnt think so if its building pressure) or is it because its only a 2hp. My 4hp cambell 20 gallon takes like 2 minutes . Where can you find a manual

Well, the voltage doesn't matter - it will run at speed or lug down and burn up.

30 gallons is about 4 cubic feet, and the pump is supposed to give 4.9 Cubic feet at 135 PSI, so around a minute from empty would be expected.

So, check for leaks, maybe a slipping belt or drive wheel loose, or the pump needs some TLC.

Good luck.
