I got a speedaire compressor 2Z869 from my dad's basement. When I plug it in, it will build pressure to 60 lbs, but as soon as I open the valve on the hose, it drops down to 0 and will not provide pressure with the valve is open, if I close it does. Do I need some kind of a pressure tank or bottle after the pressure valve, before the hose?
Comments for 2Z869 - old speedaire compressor won't keep up pressure?

Elec 2HP motor will not start under ANY pressure, though will run with belt off.
I have a 2HP portable Speedaire; less than 10 hours running, though is out of warranty (sat inside storage for couple years).
It worked fine for approx 10hrs interimitent running after removed from storage, then motor quit working.
Have gone through all accessible wiring, replaced caps, wire ends, etc. The motor will run with No-Load / no belt on. W/ no load in tank, crank turns by hand w/ small compression; if belt placed back on motor, the motor just hums until motor safety breaker throws.
The motor only has about 10 hours runtime... almost $300 to replace w/ Chinese replacement (via Grainger)... HF 1/2 that.
Called local motor repair companies, who state cost more to repair than replace..
Any ideas, or is it even worth trying to repair... Thank you

Hi Chuck...
If this is a 120 volt compressor motor, then trying to run a 2 HP with that voltage is marginal, at best.
Please add a comment below telling me that you are not using an extension cord and that you are plugging the compressor into a socket that has not got a bunch of other electrical using devices running at the same time?
If the compressor has a good power source, no extension cord, and the problem persists, and the intake filter is clean, my next check, it were my compressor, would be the start cap. You can see a page on this site about how to do that.
Cheers,
Bill
