Foaming tendency analysis assesses how easily an oil foams and how quickly the foam breaks down – important in high-agitation systems such as transmissions and hydraulics. Excessive foaming can lead to air entrainment, loss of lubricity and cavitation.
The oil is blown through with air under controlled conditions in three stages (I, II and III) that simulate different operating conditions. The amount of foam and the decomposition time are measured.
The customer gains insight into the oil's air separation properties and whether problems may arise during operation that require action or an oil change.
