• Fill-Free 1.0 – Single Product (Pure Oxygen) Semi Automated System
    • The Fill-Free 1.0™ allows the operator to enter the desired DOT fill pressure  and vacuum level, on either the Manifold “A” or “B” set-up screen, and start the fill process. The cylinder temperature is monitored and the ultimate fill pressure is automatically calculated and displayed – the same great features we’ve offered in our fully automated system for the past 15 years.
    • The operator is alerted at zero vent pressure, again for leak check, and a third time when the vacuum level is attained. Once full, the pump is automatically stopped and the operator is again alerted.
    • An optional high-pressure valve may be installed to shut off when full  pressure is attained.
  • Fill-Free 2.5 and 3.0 – Mix Gas Semi Automated System
  • Fill-Free 3.0 – Gravimetric (fill by gram weight)
