Pneumatic equipment is a system that drives equipment using the pressure obtained by pressurizing and compressing the atmosphere. It is used for labor savings and automation in factories in various fields such as automobiles, semiconductors, the food industry, etc. The power source that generates power is composed of an air compressor, aftercooler, air tank, etc. On the equipment side, it consists of an air cylinder, solenoid valve, 3-point set, air filter, regulator, lubricator called FRL, etc. In addition, there are fittings used for piping, pneumatic valves, speed controllers, pressure / flow sensors, etc. It is a clean system that uses air, and is an environmentally friendly and highly safe system. It also has the advantage of being easy to handle and better power compared to electric.
