    sprague booster issues

    seeing if anyone has come across this problem or just operator error. have a s-86-jn-30 booster. used it previous with no problems. hook everything up and when there is a load on high pressure side (supply and tank to be filled hooked up and showing equal pressure) i just get air to the cooling coller. when i take load off of high pressure side booster cycles. removed air filter/pressure regulator from drive input.

    thanks for any insight

    Sounds like the drive piston seal is leaking. If you are using it in cold weather it might solve the issue by warming the outer housing. I know mine will do this if it is too cold until it warms itself a bit.
