Ultrasonic Fluid Bed Systems

Precise, Uniform Spray for Complex Coating Applications

Ultrasonic spray technology delivers the precise, uniform spray required for delicate, complex fluid bed coating processes– such as Wurster (fluid bed) coating– while providing a high level of control over the spray, allowing users to make fine adjustments on the fly. Fluid Air will work with you to integrate Ultrasonic spray technology into your customized fluid bed processor.
