The type of motor used on light-dep walls (or something similar) is probably better than using compressed air, but it depends on how the trade-off weigh out for your needs.

The motor in the picture is electric driven not compressed air. I’m not familiar with the motor you’re referencing, can you give me more info?
I see now, I only read the title, and didn't look at the picture.
Here's an example of what I was talking about. This is what came up in a search result, so I don't know if it's high quality, or crap.
There are various sizes of these motors, and they have knobs to determine how far they should turn each direction.
