The only thing you need to be sure about with the timer is that it will handle the current for your compressor. So many of these cheap timers won't consistantly switch/carry 15A from a motor start. And if it's 20A or 220V, it will be more difficult to find a heavy duty timer/switcher.

Now if you wanted to be really clever, you would build a timer with a motor starter into a box and attach a pressure switch contol timer circuit --- if the pressure doesn't build to 20psi in 5 minutes, the circuit turns off....

Default Hey

Now why didn't I think....O" never mind....
Those are great ideas....but I think he's still replacing the connecting rods.

Hmmmm....Motion sensor compressors....scare the heck out of any unsavory characters trying to lift your stuff.

This needs to go in the invention post...........

Default what the @uc$?

I would have to say if you broke your rods, the motor would be big enough to melt a bathroom switch, or a wind up timer. The response with the motor contactor,( in the compressor world, we call this a mag start) would be the only correct help for you. But to help you properly set this up safely and to code we would need to know the volts, amps, and horse pwr. of new pump motor. If you woke up and the thing was running with broken rods, it was either toast to begin with, out of oil, or you broke a hose or pipe in the night? Anyway i'm guessing 20-30 amp 2pole? pwr. from brkr. into rated disconnect switch, then into mag start, then to compressor. On mag start there is on/off switch. If you can't remember to turn off this switch, it has a low enough current through it that you could bypass this and run through a wind up timer, NOT A PUSH BUTTON 1 5 10 15 MIN. TIMER! But a wind up timer rated for at least 15 amps and 1500 watts and I'm betting 240v for mag coil. Ask more if you need more.

I too have been wondering about getting a timer on my compressor. The problem is that if the compressor is running when the timer shuts it off, then the compressor will not bleed the back pressure. When the power comes back on, the motor is then jammed. There should be a way to make something that if the compressor is runnig, the power is left on until the compressor shuts down.

Hey... just a thought...
How about wiring in a "photo cell"?? It would have to be wired into a relay to handle the amperage probably, but you don't work in the dark do you??

I think this multi function timer should do the trick. It looks as though you just have to run a few wires, set up your timer schedule on the device, and your have an easy digital timer! Price point, not bad, especially for the technology used. Compared to other timers, like Intermatic and Tork, this seems like it would be the best fit.
