By Josh Cosford, Contributing Editor Aeration is the introduction of air bubbles within a liquid by passing through or across open air. Aeration most often occurs in hydraulic systems when oil returns to the tank above the oil level in the reservoir, entraining bubbles as it splashes into the tank. The primary worry with aeration is the … [Read more...] about How does aeration affect hydraulic systems?
