What is a pressure booster?
A pressure booster, also known as a pneumatic booster regulator or air booster, is a device that increases the pressure of compressed air locally within a pneumatic system. It operates without electricity, using only the existing compressed air supply to amplify the pressure to a desired level – typically up to 4 times the inlet pressure depending on the model. Pressure boosters are used to supply high-pressure air to specific processes or actuators without needing to raise the pressure of the entire system, offering a more energy-efficient and compact alternative to adding additional compressors. They can be combined with compressed air tanks to stabilise pressure output, reduce pulsation, and ensure consistent performance, especially in intermittent or high-demand applications.
Enhance your pneumatic system with the SMC booster regulator
Maximise efficiency and optimise pressure control with
SMC’s pneumatic booster regulators. Designed for industrial applications requiring a stable, localised increase in air supply, our
air pressure booster ensures reliable performance in compressed air systems and allows to reduce the main line pressure for an optimised energy management.
Key Benefits of the SMC booster regulator:
- Increased air pressure – The air booster effectively rises the equipment inlet pressure, providing enhanced force for pneumatic tools and actuators.
- Energy-efficient performance – Our pressure booster operates without electricity, utilising only compressed air for cost-effective amplification
- Optimised air delivery – When combined with a compressed air tank or air receiver, they ensure consistent pressure supply and minimise fluctuations in demand.
- Compact & easy integration – The lightweight design allows seamless installation in existing air supply networks.
Typical applications for pneumatic pressure boosters
The
SMC booster regulator is essential in industries where consistent, high-pressure compressed air is required. Common applications include:
- Automated manufacturing & assembly lines – Provides stable and increased pressure for applications such as leak testing, crimping and impact blowing
- Injection moulding & packaging – Ensures precise and efficient operation of pneumatic cylinders in moulding and sealing processes
- Automotive – Supports high-pressure air requirements for testing equipment, painting systems, and tire inflation stations
- Food & beverage processing – Maintains optimal pressure for process valves, blow moulding, and packaging automation.
