    This doesn't sound right, who would manufacture a compressor that ran like this? what happens when you turn it on? it goes full throttle? When you shut it down are they shut down while in full throttle? If they are newer models I would think they are adjustable by the outlet valve.

    It just sounds like the rental guys want to protect themselves which is fine but a good way to have you go look someplace else, if they are renting out lots of these to larger companies they might not want to bother with renting you one for one day.

    I use a regulator like this, only bigger (1" ports) to handle more CFM. Works great.

    Well thank you very much for the advice, I will research the machines they rent before doing anything. Should they somehow not have a built in regulator I will go out and buy one.

    I appreciate the help with this guys

    Guess the idea of only opening the ballvalve 1/2way never entered his mind.

    I'll bet there is a regulator of sorts built into the machine. Meaning, the compressor will run wide out if you are using all the cfms quickly and run slower if you are just using a trickle.

    So, just open the valve a little bit after hookup to the irrigation blowout POC. After a bit you'll learn how much to open the valve without damaging things depending on how many zones you purge at a time.

    Are there no dial gauges on the machine?

    I'll bet it has an adjustable regulator, they probably just don't want you messing with it.
    My IR 175 has one and I can adjust it between 65-130 PSI.
    I adjust it several times a day from dinky systems to sports fields.

    i've run up to 500 cfm, one way or another the pressure is adjustable, my 125 has a governor, a built in regulator and i plumbed a regulator on a tee for small tools.

    if i were renting (with the exception of a small truck mount) and that's the way to go if you don't use it for other work. i would buy a regulator attach it to a piece of angle iron with a magnetic base and bolt clamps.

    slap it on the frame and clamp it for security, moves from compressor to compressor in an instant.
