SMC 10-AS2002FSM-03 | 10-FSM/FSC Series Clean Room Speed Controller With Indicator In-Line Type Body 2 3/8 Port Flow Rate Display

The SMC 10-AS2002FSM-03 is a clean room specification speed controller with integrated flow rate indicator from the 10-FSM/FSC series, configured in an in-line type body with 3/8 inch port connections. Unlike standard speed controllers that require trial-and-error adjustment, the FSM series includes a built-in visual flow rate indicator that displays the current air flow setting, enabling operators to set and verify cylinder speeds precisely and reproducibly without external measuring instruments.

Why choose a speed controller with a flow indicator? In clean room automation, repeatable cycle times are critical for process consistency and yield optimization. A speed controller with integrated indicator allows operators to set exact flow rates during commissioning and return to those same settings reliably after maintenance, tool changes, or production recipe switches. The indicator eliminates guesswork and reduces the time needed to dial in actuator speeds, directly improving equipment changeover efficiency.

The in-line body configuration ("FSM" type) mounts directly in the tubing run between the valve and cylinder, providing a streamlined installation without the elbow or bracket-mount configurations required by other speed controller styles. Body size 2 with 3/8 inch ports ("03") handles moderate flow rates appropriate for mid-bore cylinders and actuators common in semiconductor handling equipment and pharmaceutical automation.

The "10-" clean series specification provides fluorine grease, clean room assembly, and anti-static double packaging. This speed controller is RoHS compliant and integrates with SMC's clean series pneumatic components for comprehensive clean room motion control systems.
