Capable of purging very long grid sections of mains with multiple combinations of pipe diameters in a very short time without creating turbulence or without the need of introducing an inert gas.
  • Typical ability to purge over 4000' of 8" diameter main in about 11 minutes.
  • No need for expensive & slow moving inert gas.
  • Use with existing air compressor.
