The 05 from Parker Hannifin, Pneumatic Div., Richland, Mich., provides high flow in a compact package. It is used to prepare compressed air for machinery and automation consumption. Reportedly smaller than competitive FRL units, it handles flows exceeding 50 scfm. Modular accessories — including pressure switches and lockout, slow-start, and quick-dump valves — let users bundle machine control and pneumatic functions directly at the FRL. The 05 can be used with pipe nipples or as a modular unit in 18, 14, and 38-in. NPT or BSP ports. It is suitable for applications using actuators with a 3.25-in. bore or smaller, typically found in packaging or assembly and automation equipment.
