K88500 Air Release Value Apparatus


 


 

Test Method
The ability of a turbine, hydraulic, or lubricating oil to separate entrained air is a key performance characteristic in applications where agitation causes a dispersion of air bubbles in the oil. To determine air release properties, the sample is heated to a specified test temperature and blown with compressed air. After the air flow is stopped, the time required for the air entrained in the oil to reduce in volume to 0.2% is the air bubble separation time.

Features and Benefits
• Conforms to ASTM D3427, IP 313 and related specifications

• Optional data acquisition software package automates sample density measurements and provides additional tools for the calculation of the air release value, the first order rate of air release, and the volume percent air versus time

• High accuracy temperature control with digital setpoint and display

• Digital control panel leads user from start to finish of test operation

• Automatic calculation of final sample density for determination of air release value

• Redundant overtemperature protection circuitry assures safe operation


 

K88500 Air Release Value Apparatus
The Koehler Air Release Value Apparatus consists of a test vessel and air flow control equipment for delivering heated air at the specified flow rate to a lubricating oil sample maintained at constant temperature. Microprocessor-based control panel guides user from start to finish of test operation and provides density calculation and timing operation for measuring the air release value of the test sample. The system includes drying oven for warming test oil at temperatures of up to 100°C; circulating bath with digital temperature controller and air bath for sinker; non-pulsating air pump; compressed air heater with digital temperature controller, overtemperature and overpressure protection circuitry; pressure gauge; thermometer. Optional Windows® software automatically measures the time for air release and calculates the first order rate constant for air release and the volume percent of air versus time. Jacketed sample tube with air inlet and outlet tubes and baffle plate is ordered separately.
