Gas Assist injection molding requires a reliable supply of clean nitrogen gas.  This is accomplished by supplying the Gas Kit with nitrogen from pressurized bottles, a Nitrogen Generator, or from a central nitrogen system.

 The primary requirements are a clean supply of nitrogen (as contaminated gas can cause problems with the gas delivery system), and a minimum nitrogen input pressure of 500 PSI.  The Senior Gas Kit intensifies the pressure to 10,000 PSI internally from the gas source.  Maximum input pressure is 2,500 PSI. 

  Obviously, the higher the input pressure, the less the pressure has to be intensified internally. Nitrogen Generator delivers a continuous supply of nitrogen at 2,500 PSI, at up to 99% purity, and can supply nitrogen to up to 3 Gas Kits.  When a molder operates numerous Gas Kits, they may find it economically advantageous to convert to a central nitrogen system.
