    Hey, I have an opportunity to buy a 1990 Sullair 100 CFM compressor. It has around 1300 hours on it, newer tires, and was just gone threw at the dealer. Now I usually rent a Sullair 185cfm, and that has always been great. I dont do any huge commercail systems. Am I going to regret going to a smaller unit, as I can get it for around 2800. I would really like to have my own compressor instead of depending on the rental company. Does this sound like a good deal or not? :dizzy:

    We have a 125CFM, I would think the 100 would do fine..mite not be able to
    do entire systems at once, but owning your own is a great idea...by the way,
    the compressor is valuable for locating leaks, as air bubbles surface, showing
    the location (& sound!):)

    I've used 100 CFM compressors on industrial park systems of 100 gpm or so (2 inch zone valves) and no problems.

    I have the exact same compressor and it will blow out 1-4 zones at a time. I also have a 2006 IR 185. I would say the 185 is three times the compressor but the 100 will do you fine. If you can still rent the 185 and have employees, try to keep them both busy at least during the peak of the season.

    Does that seem like a decent price to pay for that compressor?

    Manual operation of the zone valves.
