Product Overview
The METAL WORK 3683031 / FR 200 1/2 5 08 SAC is a high-precision pneumatic filter regulator unit engineered by Metal Work, a globally recognized manufacturer of pneumatic and fluid power components. This combined FRL (Filter-Regulator) assembly integrates a coalescing filter element with a diaphragm-type pressure regulator in a single compact housing, providing both air filtration and downstream pressure control within one installation point. The unit operates on a balanced poppet valve principle, where the adjustable spring force acts against the downstream feedback pressure to maintain a stable secondary pressure regardless of fluctuations in inlet pressure or flow demand. With a 1/2″ port size and a 5-micron filtration rating, the FR 200 series is designed for general industrial compressed air systems requiring clean, regulated air supply to pneumatic actuators, valves, and instrumentation. The SAC designation indicates the specific configuration variant within the Metal Work FR 200 platform, ensuring direct interchangeability with OEM-specified components.

Engineering Features & Advantages
- Precision Performance: The balanced poppet regulator design delivers accurate and repeatable downstream pressure control, minimizing droop and compensating for inlet pressure variations to protect sensitive pneumatic equipment.
- Integrated Filtration & Regulation: Combining a 5-micron filter element with a pressure regulator in a single body reduces installation footprint, piping connections, and potential leak points compared to separate filter and regulator units.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust housing and diaphragm assembly resistant to typical compressed air contaminants, oil carryover, and condensate.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Metal Work FR 200 series specifications, ensuring drop-in replacement without modification to existing pneumatic circuits.
- Direct Fit Replacement: Precision-manufactured to original METAL specifications for direct replacement, minimising downtime and eliminating fitment issues.
