Almost all 5 lpm units have plastic or some sort of non-metal flow ball. Even the Devilbiss, Invacare, PB 590 and the Millennium. By taking out the plastic ball and replaceing it with the metal, we are able to achieve 10 lpm and still keep the ball in the range. We use a lab rated flow meter on all the units that we modify to insure that they putting out what ever flow level is set. If you really did a check you would find that this is true. Please get your facts straight before posting them. You are only confusing people in your effort to discredit my company. Also anyone out there can do the test themselves. Just take a strong magnet, place it against the flow meter and move it up and down. If the ball is steel it will follow the magnet, if not it wont.
