Air release characteristics indicate the ability of lubricating oils to separate entrained air bubbles. Oils with poor air release properties may cause problems such as cavitation, pump instability, and reduced lubrication efficiency in hydraulic and turbine systems.

This instrument evaluates the air release performance of petroleum products by measuring the time required for entrained air to separate from the oil under controlled temperature conditions. It is commonly used for testing hydraulic oils, turbine oils, and other lubricating oils.

The Air Release Value Tester integrates precise temperature control, built-in air supply, and intelligent microprocessor control to ensure accurate and reliable test results.

It is widely used in petroleum laboratories, power plants, lubricant manufacturing facilities, and research institutions.

The Air Release Value Tester is suitable for evaluating air release properties of:

• Hydraulic oils
• Turbine oils
• Industrial lubricating oils
• Mineral oils

Typical application environments include:

• Lubricant manufacturing plants
• Petroleum refineries
• Power generation companies
• Hydraulic system maintenance laboratories
• Research and testing institutions

The instrument adopts an STM microprocessor with adaptive PID control algorithm to automatically regulate the heating process according to the standard testing requirements.

An 8-inch color touchscreen display with Chinese and English interface provides intuitive operation and clear display of test parameters.

The tester includes a high-capacity internal air pump, eliminating the need for an external gas source. Air pressure can be finely adjusted within a range of 0–0.2 MPa.

A specialized air constant-temperature device ensures consistent temperature between the oil bath, air supply, and measuring instruments, improving test accuracy.

The instrument precisely controls both water bath temperature and air temperature, ensuring stable testing conditions.

The system features low-water alarm and automatic water refill functions, preventing damage to heating components caused by dry heating.

The instrument supports multiple language interfaces and allows software upgrades when testing standards are updated.

This Air Release Value Tester complies with the following standards:

• ASTM D3427 – Standard Test Method for Air Release Properties of Petroleum Oils
• SH/T 0308 – Determination of Air Release Value of Lubricating Oils
