High frequency oscillatory signal which brings by ultrasonic issued ransducer into high frequency mechanical oscillatory, then it transfer to liquid and comes into being cacitate effect. Which is generating hunderds of very small bubbles, small bubbles are oscillatory blasting and regeneration in the rapid process of compression and expansion, produce a strong catalytic role and emulsion, and impact depth, surface and harbourage of the objector to get rid of degreasing, decontamination, carbon and get a comprehensive cleaning effection.
