Ordering by number: this is 3310148800, the Atlas Copco valve housing. It directs the flow that reverses the piston in the tool. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
Give us the model and serial off your machine and we will confirm the fit; the parts diagram library and the Atlas Copco tool range are the other two places to start. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
