The G5 Flimm-Fighter Percussor is the optimum percussor for effective postural drainage at home. The Flimm-Fighter incorporates Directional-Stroking action that helps loosen congestive materials and then moves them into the upper airways, thus promoting airway clearance. The red arrow on the head of the Flimm-Fighter shows the user the direction that the loosened materials are moving inside the body. The ultra-light applicator head, weighing less than one pound, allows a patient to effortlessly receive or self-administer therapy, as it is designed for use with our self application pillow*. The continuously-variable speed range of 20 - 30 cycles per second ensures that patients receive safe, thorough treatment. Comes with applicators 250, 251, 253 & 234.
