Air Boosters

Festo Air Boosters

Festo air boosters are engineered to safely and efficiently increase compressed-air pressure within a defined section of a pneumatic system. They deliver controlled and steady pressure amplification using a purely pneumatic operating principle—enabling users to reach higher pressure levels for specialized actuators, clamping devices, pressing applications, or high-force motion tasks.

These boosters are compact, durable, and optimized for industrial performance, offering high efficiency with minimal air consumption. They allow localized pressure intensification without requiring an expensive high-pressure compressor or modifying the entire plant’s pneumatic network.

⭐ Important: Air boosters provide high outlet pressure from a standard supply line—significantly increasing force output while reducing system cost and energy usage.

Design & Functionality

Festo air boosters function as pneumatic pressure amplifiers. Incoming compressed air drives an internal piston system that multiplies outlet pressure based on the booster’s amplification ratio. The process is fully automatic and requires no electrical power, making it ideal for decentralized operation within machines.

Available in multiple sizes and pressure ratios, these boosters supply stable, ripple-free pressure to downstream components. Integrated non-return valves prevent backflow, while optional air reservoirs ensure consistent flow for dynamic applications.

⭐ Important: The purely pneumatic operating design ensures simple installation, no electrical integration, and high reliability.

Beam Pitch Options

(Translated as: pressure ratios, flow variants, installation configurations)

Multiple pressure amplification ratios available, such as:
• 1:2 pressure boosting
• 1:3 high-pressure versions
• Model-specific ratios for special applications

Configurable performance options include:
• Different nominal flow rates
• Options with or without integrated air reservoir
• Compact, panel, or inline mounting layouts
• Models with pressure regulators for precise control

Additional selectable features:

• Low-noise versions
• Reinforced variants for high-pressure zones

⭐ Important: Flexible pressure ratios and flow options let the air booster match exact force and performance requirements without overhauling the air system.

Intrinsic Synchronism

Internal piston assemblies and check valves ensure synchronized pressure multiplication with minimal fluctuation.

Optional external accumulators stabilize boosted pressure for applications requiring fast actuation or high dynamic load changes.

Ensures consistent pressure output, supporting reliable pneumatic motion and machine repeatability.
