Your units don't make sense. " maximum speed is 70 m/hr" is speed, not volume.

This question should be directed to two or three vendors that you can find here:Search GlobalSpec

Just to amplify the point made by lynlynch, the best thing you can do is contact several suppliers of compressors and associated gear, and ask each for their advice, and the cost of suitable equipment. Ask for it in writing (e-mail is OK).

When you have your replies, study them, then contact the suppliers again, armed with new insight.

In defence of the suppliers, they know their equipment and its capabilities, but (if they have something in the right range) they will try to sell you something.

Good ones won't you crap.

Presuming that was intended to be 70 m3/h per machine, a cfm comparison would be 2 x 70 x 35.31 ÷ 60 ≈ 82.4 cfm.

This sounds suitable for a rotary screw compressor of about 20 hp (~15 kw), plus dryer. If flow to the machines doesn't fluctuate too much, a tank might be optional.

Beware that a single compressor "puts all your eggs into one basket." Screws are quite reliable, but you still might want to consider two units. Also, once you have air available, you may find other uses for it--possibly indicating a larger choice.

You're quite welcome. Good luck with your installation. (Please avoid all-capitals text in postings. Drawings sometimes use all-capital letters, but in prose text they are considered as "shouting.")

This is a common size of air compressor, and you are likely to find local (or at least regional) sources that can furnish it in the correct voltage and Hertz.
