FESTO MS Series Distributor Blocks

Festo FRM-FRZ Distribution Blocks are engineered for efficient and reliable air distribution in modular pneumatic systems. Designed to branch air flow to multiple outlets, these modules seamlessly integrate into MS-series service units to maximize system flexibility and performance.

Each distribution block supports a compact, space-saving footprint while delivering high flow rates and robust corrosion resistance. Available in multiple port sizes and configurations—including MS4N, MS6N, and MS9 variants—they’re ideal for applications requiring decentralized air supply to multiple actuators or zones.

Key Features:

  • High flow capacity for simultaneous multiple connections

  • Port options include G1/4, G1/2, and NPT variants

  • Operating pressures up to 20 bar

  • Temperature resistance from -10°C to +60°C

  • Die-cast aluminum housing for strength and durability

  • UL Recognized and RoHS compliant

  • Suitable for applications with moderate corrosion exposure (CRC 2)
