These replacement piston modules are designed to maintain standard physical chest compression resistance for PRESTAN Ultralite Manikins. Engineered to fit directly into the inner chest cavity of the Ultralite torso frame, these mechanical pistons provide a calibrated down-stroke feel to simulate realistic adult chest compliance during training. This specific series does not contain electronic CPR feedback wiring, making it the correct match for standard non-monitored Ultralite manikins or for training scenarios where visual rate monitors are not required.

The multi-unit packaging includes a dedicated protective zippered carrying case to organize and transport your spare classroom inventory safely.
