STEM Kit Strong Pneumatics, Powerful models powered by pneumatic energy The use of pneumatic engines is indispensable in many areas. These engines include, on the one hand, the compressed air system, and on the other hand, the unlimited fuel - air that guarantees long-term operation. The 6 pneumatic models illustrate pneumatic functions and the use of compressed air, and the realistic components allow for quick understanding and promote technical imagination. These models use pneumatic valves and hoses, the compressor or exhaust air flaps to demonstrate the many modes of operation and thus allow various movements to be performed. In addition to the educational purpose, the Strong Pneumatics kit offers young engineers adventure and fun. Assembly instructions to build 6 models powered by pneumatic energy. Contains 660 pieces.
