<p>Air bubble massage bath has the drive angular speed selected by electronic timers according to required physical program. The monotonous nature of the treatment is mitigated, and the physical effect is strongly changed numerous times, at controlled intervals, e.g. the turbine initially runs at 1/2 speed, then at full speed, and after a given time abruptly switches off, then restarts at full speed or slowly. This process can be repeated and correspondingly programmed at will.</p> |
