An air booster is a device that uses pneumatic or hydraulic principles to amplify the pressure of ordinary factory air sources (such as 0.6-0.8 MPa) several times, outputting ultra-high pressure air (up to tens to hundreds of megapascals). Essentially, it is a pressure converter, not a traditional air compressor.


Features and Advantages

1. Extremely High Output Pressure

A core advantage, easily achieving ultra-high pressures unattainable by ordinary air compressors.

2. Energy Saving and Economical

Requires only a small amount of driving air to generate high-pressure output, eliminating the need for an expensive high-pressure main air compressor.

3. Safe and Explosion-Proof

Purely pneumatically driven, generating no electrical sparks, making it particularly suitable for flammable and explosive environments.

4. Simple Maintenance

Cmpact structure, few components, and high reliability.

Applications

• Air tightness testing

High-pressure leak testing of valves, pipes, and automotive parts.

• Gas-assisted injection molding

Providing a stable high-pressure air source for injection molding machines.

• Localized high-pressure air source in factories

Supplying air to specific tools or equipment (such as pneumatic presses and riveting tools).

• Aerospace

Simulating high-altitude environments to test the pressure resistance of components.


FAQs

Q: What's the difference between it and a high-pressure air compressor?

A: An air compressor "manufactures" compressed air; a booster compressor "increases" the pressure of existing compressed air, used as a localized pressure boosting device.


Q: What conditions are required to use it?

A: A basic factory air source is needed as power. Low-pressure air must be input to output high-pressure air.


Q: Is the output flow rate very small?

A: Yes. The core of a booster compressor is high pressure, not large flow rate. It is suitable for operating conditions that require stable high pressure but have low air consumption.
