1. If the gas consumption is not large equipment, such as small-diameter pneumatic switching valves, often using copper cable 6mm * 1mm, the inner diameter of 4mm can be. Large diameter, DN250 above the use of copper cable 8mm * 1mm.
2. If the equipment group, it is recommended that galvanized pipe laying to the site, an additional set of air tanks to stabilize the pressure.
3. If a soft gas supply pipe such as PU pipe is used, this distance will be shorter due to pressure loss.
4. The distance is too long, should consider the delay can not affect the process requirements.
