To ensure the efficient transmission of power, a hydraulic oil must be able to resist being compressed. Pressure applied to new hydraulic oil will be transmitted efficiently and instantaneously, but any air entrained in the oil, for example by foaming, will affect its compressibility; reducing the transmission efficiency and possibly resulting in inadequate lubrication, cavitations, oil loss and even mechanical failure.
The oil must therefore have good air-release and anti-foam properties. Tellus products meet all industry standards for air release and anti-foaming, such as IP 313 and IP 146.
