Air Pressure Booster

What Is an Air Pressure Booster?

An air pressure booster is a pneumatic pressure amplification device designed to increase the pressure of pre-compressed gas. It uses compressed air as the driving power source to increase the pressure of an existing compressed gas supply from cylinders or pipelines, providing higher outlet pressure for industrial applications. Air pressure boosters are commonly used for gas filling, pressure testing, calibration, gas transfer and high-pressure pneumatic systems. Depending on gas medium compatibility, sealing design and material selection, they can be applied to various industrial gases including nitrogen, oxygen, hydrogen, helium, argon and other special gases.

How Does an Air Pressure Booster Work?

The working principle of an air pressure booster is based on a pneumatic piston amplification mechanism. Compressed drive air enters the drive chamber and pushes a large-area piston connected to a smaller gas compression piston. The difference between the two piston areas creates a fixed boost ratio, allowing the booster to increase the pressure of the incoming gas supply. During operation, the compression piston repeatedly pressurizes the incoming gas until the required outlet pressure is achieved. When the outlet pressure reaches the balance point, the piston automatically stops moving, and the booster restarts when system pressure decreases due to gas consumption or leakage.

Why Choose ATO Air Pressure Boosters?

ATO air pressure boosters are designed for industrial applications requiring reliable pressure amplification from pre-compressed gases. The series combines fixed boost ratios, high-pressure capability and standardized construction for easier selection and installation.

• Wide Boost Ratio Range from 7:1 to 100:1: The series offers seven fixed boost ratios ranging from 7:1 to 100:1,allowing users to select the appropriate model based on required outlet pressure and flow demand. The available ratios include 7:1, 10:1, 15:1, 25:1, 40:1, 60:1 and 100:1. Lower ratio models provide higher flow capacity, while higher ratio models are designed for higher pressure applications.
• High Outlet Pressure up to 800 bar: The series supports maximum theoretical outlet pressures from 56 bar to 800 bar. The highest boost ratio model provides up to 800 bar outlet pressure, suitable for ultra-high-pressure applications including laboratory testing, pressure calibration and high-pressure component testing.
• Pneumatic Drive Without Built-in Electric Components: ATO boosters use compressed air as the driving source and do not require built-in motors or electrical control systems. This design simplifies installation where minimizing electrical components is preferred and provides a practical solution for industrial gas boosting.
• Automatic Pressure Maintenance with Integrated Cooling Design: The internal pressure balance structure allows automatic stop and restart according to system pressure changes. Integrated cooling structures help reduce heat accumulation during continuous compression cycles and support stable operation under rated conditions.
• Air-Gas Separation Structure: The drive air chamber and gas compression chamber are separated to reduce contamination between driving air and process gas. The design helps support cleaner gas transfer applications where oil contamination needs to be minimized.

Which Air Pressure Booster Fits Your Application?

Selecting an air pressure booster requires matching the required outlet pressure, inlet gas pressure, flow demand, available drive air supply and gas compatibility. ATO series gas booster pump is a single-stage booster pump. In order to achieve the required outlet pressure, the input air pressure at the gas inlet needs to be pre-pressurised to a certain extent. The pre boosting pressure varies with the maximum pressure, and the maximum pressure can be boosted to 80MPa.

• High-Flow Gas Filling & Gas Transfer: Systems requiring higher gas delivery capacity rather than maximum pressure amplification are better suited to lower boost ratio models. The 7:1 and 10:1 configurations are suitable for cylinder charging, nitrogen filling, gas transfer and other industrial gas boosting processes where stable flow output is required.
• Medium-Pressure Charging & Industrial Testing: Medium-pressure systems require a balance between pressure capability and flow performance. The 15:1 and 25:1 configurations are suitable for accumulator charging, industrial gas supply and general pressure testing applications.
• High-Pressure Calibration & Component Testing: Advanced testing systems require greater pressure amplification capability with controlled gas output. The 40:1 and 60:1 configurations are suitable for valve testing, pressure vessel inspection, pressure gauge calibration and component verification.
• Ultra-High-Pressure Research & Specialized Applications: The highest pressure configurations are typically used for specialized testing and research rather than continuous high-volume gas delivery. The 100:1 configuration is suitable for laboratory testing, gas research and specialized pressure systems.

FAQ

Q: Can an air pressure booster replace a high-pressure compressor?
A: No. An air pressure booster increases the pressure of an existing compressed gas source, while a high-pressure compressor generates compressed gas from atmospheric air. The suitable choice depends on whether an existing gas supply is available.
Q: What should I confirm before selecting an air pressure booster?
A: Confirm the available inlet gas pressure, required outlet pressure, gas medium, required flow rate and available drive air supply. These conditions determine the suitable boost ratio and model selection.
Q: Can an air pressure booster increase pressure from zero?
A: No. An air pressure booster is designed to amplify the pressure of an existing compressed gas source. The inlet gas must have a certain pre-pressure level to achieve the required outlet pressure.
Q: Does the installation require a special air supply system?
A: The booster requires a clean and stable compressed drive air source within the rated operating range. Proper filtration and air quality help reduce contamination and extend sealing component service life.
