MS Series Filter Regulators

Festo MS Series Filter Regulators

Festo’s MS Series filter regulators are designed as comprehensive compressed-air preparation modules, bringing robust filtration, precise pressure control, and modular flexibility to automation systems. They are ideal for a wide range of industrial applications — from general machine automation to environments with demanding performance or certification requirements. 

Design & Functionality

The MS Series combines a high-flow filter unit and a diaphragm regulator into a compact housing: the filter provides effective particle and condensate separation, while the regulator ensures stable output pressure with low hysteresis and built-in return-flow or secondary-venting functionality. These units are available in multiple sizes (e.g., MS4, MS6, MS9, MS12) offering a wide flow-range for varied system capacities. 

⭐ Important: The MS Series offers modular combinations, enabling you to mix and match filter, regulator, drain and sensor modules for tailored compressed-air solutions.

Total Crossed Beams
This refers to the coverage across flow capacities, connection sizes, and performance levels: the MS Series ensures full operational capability across machine types, from small handling systems to large-scale process installations.

Beam Pitch Options

The system offers multiple configuration options:
• Choice of sizes (MS4 to MS12) for matching flow demands. 
• Filtration grades (5 µm or 40 µm) for different air-quality requirements. 
• Pressure-regulation ranges (e.g., 0.3 … 7 bar, 0.5 … 12 bar, up to 16 bar) depending on variant. 
• Condensate-drain options: manual, semi-automatic or fully automatic; with metal or polycarbonate bowls. 
• Certification options such as ATEX/UL for use in explosive atmospheres (Zones 1/2/21/22). 

⭐ Important: The broad configuration range ensures an optimized solution for flow performance, air purity, pressure stability or certified environment — whichever the application demands.

Intrinsic Synchronism

Internal diaphragm-regulator design and integrated return-flow function guarantee consistent pressure output even under varying inlet conditions. The modular service-unit mounting enables quick replacement of individual modules without disassembling the entire unit. 

Operational Advantages

• High flow rates in compact footprint — maximizing system throughput while saving space. 
• Excellent particle/condensate separation for reliable downstream pneumatic components.
• Low hysteresis pressure regulation for precise control of pneumatic systems.
• Modular service-unit concept reduces maintenance time and simplifies system upgrades. 
• Customizable for hazardous environments (Zones 1/2/21/22) — flexible across industrial sectors. 

Applications: Machine automation, packaging lines, handling systems, compressed-air distribution, process plants in regulated or explosive-atmosphere zones.
