PROMETHEUS Aero Cylinder Head Ver.2

Based on the hard condition by reciprocating motion of nozzle, selecting duralumin material which have strength, durability, and antifriction. Also, it is treated by alumite for hardness up and reducing the friction damage. To keep the center position of nozzle, using all high-quality cutting method. Further, taper machining has been proceeded at an air inflow side for keeping flow rate and improve rectification of air effect.
