SMC Corporation AC30B-03CG-5-AF Combo Modular Valve

The SMC AC30B-03CG-5-AF Combo Modular Valve is a compact F/R COMBO MODULAR unit from the AC30B family that integrates a filter, regulator, and lubricator in a single modular block for streamlined air preparation in pneumatic systems. The 03CG variant denotes a 3/8 in NPT port configuration, and the unit features a polycarbonate bowl for clear visibility and durable service. It carries a 5 μm nominal filtration rating aligned with the AF option, helping to deliver cleaner air to downstream actuators. The regulator portion provides an adjustable set pressure range from 0.05 to 0.7 MPa, enabling stable downstream pressure across a variety of pneumatic circuits. This modular FRL assembly is designed to mount alongside other AC30B components and is described by SMC as interchangeable with the existing modular AC line, simplifying upgrades and maintenance. Common applications include automation equipment and machine tooling where reliable, preconditioned air is essential for consistent valve and actuator performance. The AF designation reflects the module’s filtration capability within the FRL family, ensuring consistent air quality across modular configurations.
