A pneumatic liquid intensifier's primary function is to amplify fluid pressure using compressed air as the driving force. This device converts low-pressure air into high-pressure liquid, enabling applications that require significant hydraulic force without relying on electric power sources. It's commonly used in scenarios where precise and powerful fluid control is essential, such as hydraulic testing, clamping, and actuation systems. By utilizing compressed air, pneumatic liquid intensifiers offer advantages like safety in explosive environments and flexibility in mobile applications.
