Parlor air compressor

What size air compressor would I need to operate a 20 unit parlor with drafting, ARCs, rapid exit system for cows, and the like?

put in big enough so as to have capicty during milking so as not to be starting up/off during milking. It also allow decent amount of air if your using it to shift something tight in the workshop. What are they recommending?

Why. That would mean a pretty huge tank on the compressor. My compressor starts and stops many times during milking bu its automatic so who cares, The main thing is that its not running all the time and getting hot

I suppose the larger capacity ones will reduce the on/off frequency of the motor thus increasing the life time of the compressor?

Thinking of getting a used tank, as big a tank as I can get and maybe a new motor. What do ye think? Or should I just bite the bullet and buy all new?

Because it runs only after milking for approx5 min i reckon, never timed it but is short. Therfore you reduce frequency start up thus reducing consumption . It also allows for air tools to operate with more power as there is more reservein tank.

How big a tank are you guys talking. I have 150 or 200 litre tank and the compressor starts up after every batch of 20 cows are fed. It takes a fair bit of air. If i was going to only need it to start once a milking i reckon i would need 1000 litre tank minimum. Which is not really practical or economic

Have a 270 litre and another moblie tank of same size for field/transport/repair /puncture.
