Bauer CII/DV-E3 6cfm compressor

That's a super deal, jump all over it. That's no toy that's a real industrial last forever compressor. It will be worth the same money 20 years from now. Plus you have the real expensive oil/ water separators with it along with a serious, expensive, safety valve and HPA control switch and electronics none of which are resident on the cheap UNSAFE Chinese specials. It also has excellent cooling between each stage.

Don't be afraid of using a phase converter, they work very well and you see them for sale all the time used.Under no circumstance should you replace a 3 phase motor with a single phase. They are NOT equivalent. That compressor needs much more starting motor torque than a single phase motor can provide. Unlike a low pressure pump there is no unloading valve when the compressor stops, so this pump is designed to deal with system pressure at startup. That CFM rating is ambient atmospheric pressure volume, not compressed volume. Multiply the CFM by 3.8 to get the liters per minute. I have an older Bauer and it's rated at 80 liters per minute. It will pump up a 12 liter bottle from 170 bar to 235 bar in about 10 minutes, just to put things in perspective. I can then shoot my PP700 for about a month from that 12 liter bottle shooting about 5 days a week 40 rounds a day..

Edit: I should add the disparity between 6 CFM and 140 ltrs a minute could be that the 6 CFM is not at 1 bar (sea level) but the rating may be at 8 bar, similar to low pressure compressor ratings in the USA. Note also the current motor is a 2 pole or high speed motor not a 4 pole. Even though the motor is labeled 60 Hz, it will also run as well on 50 Hz, but it would then run about 20% slower. This would change the 182 Ltr a minute in the volume conversion math back down to the advertised 140 ltr a minute volume. One more point, there is a wiring chart glued to the inside of the motor wiring cover that tells you how to rewire the power feed to the motor for either high or low voltage. Very simple.

I ended up converting it to single phase 240v and it works great. Though im confused about the cfm it says 5 cfm capacity and 6 cfm charging rate.
