commercial actuator are too flimsy for hw use, especially with smidsy as the lifter is on the front most commercial actuator will break when 100kg drives into it.

imo best thing to do would be to put in a small 20oz co2 bottle, tev reg, small 5/2 24v valve and a small pneumatic ram. that option would cost around, £100 cheaper than a new commercial actuator and a whole load better. you can put flow reducers on your valve then you can have your lifter fast as you like.
