[1] [2] The Rotary, Pressure-swirl [3] or Twin-fluid Atomizers [4] are the most common methods for spray ...
Rotary atomizers are able to get higher transfer efficiency compared to other spray guns because of its unique spinning bell cup. The bell cup inside the applicator, spins the material at 20,000 to 60,000 revolutions per minute. Due to the high rotation speed, the paint is subjected to high centrifugal force. This forces the paint to flow along ...
