description The invention provides an automatic vacuum degree-balancing defoamer for a vacuum oil filter and a control method thereof. In the method, a central processing unit comprehensively controls a vent valve and a vacuum degree control valve, the vent valve is opened and simultaneously the negative pressure produced by the operation of a vacuum valve is reduced, so defoaming is performed in a combination way of introducing outside air and reducing the working strength of a vacuum pump and the vacuum degree in a vacuum separating tank is automatically regulated to an optimum vacuum degree that moisture and harmful gases are effectively separated from oil and few oil foams are generated. The oil in the vacuum separating tank is isolated from directly contacting with the outside air, secondary pollution of impurities in the outside air, such as dust and the like, on the oil is reduced and foams are avoided by the method for automatically regulating the vacuum degree by the central processing unit and manual interventi
