This system is recommended for the protection of your pneumatic rammer and includes a Y strainer, water separator and pressure regulator. The Y strainer collects any particles. The water separator prevents packers from getting clogged which leads to rammer malfunction. The pressure regulator controls the supply of air to the pneumatic rammers. The maximum flow rate is 165 CFM.
