Air cannons can't hit concrete, but the machine that can hit concrete is a pneumatic pick, which is also powered by an air compressor. Choosing a pneumatic pick requires consulting a professional supplier. You can't choose the machine according to the parameters, but you need to choose it according to the actual use and workload. For example, what specifications of shovel head and chisel head are used, how big the workload of concrete is, and how durable it is.
