I looked on an industrial supplier site and found the stroke of a cylinder of 28-36 inches. the bore was 1 1/4 inch and I'm assuming the ram's rod to be 3/8 inch. the force needed to open the door again I'm assuming would be about 12 pounds through the flow control. how is the compressor a problem? once it's up to pressure it shuts off and if you have no leaks it should maintain pressure. when the cylinder operates there may be tiny leaks around the packings but other wise nothing hazardous. about the only loss in air is once for each stroke.

Its not a huge problem, just the noise it makes mainly. I think I'm going to try a 2 gal compresser that I already have. THe door is in the basement actually, so i'll have to run a line through the ceiling (Floor joists) that way i can leave the compressor in the garage. I was just wondering how large it should be is all, thanks fo you help again, i'm going to try looking at tractor supply and see if they have anything good.

o and is this the right type of cylinder? It doesnt appear to have a spring recoil, but the weight of the door should push it back...
