Congratulations on your purchase of the Pacific Ultrasonics PU series ultrasonic cleaner. 

What is Ultrasonic Cleaning?

Ultrasonic cleaning is a process created by high 
frequency soundwaves. The soundwaves, enhanced 
by specially formulated cleaning solutions, create 
high energy “cavitation”. During cavitation, millions 
of tiny bubbles form and then collapse, or implode, 
releasing enormous amounts of energy and 
shock waves which scour the surfaces of parts and 
components placed in the cleaning solutions.
This powerful scouring action reaches into minute 
crevices and blind holes which manual brushing 
cannot reach. The combination of energy, and 
specially formulated solutions, make ultrasonic 
cleaning THE most effective method of removing 
gross and microscopic debris.
