IV inline eliminates the need for an on-off valve on each air-supply tank,allowing you to convert any air-supply tank to on-off control. It also eliminates air waste that occurs when the air supply is removed from the marker or remote system. To remove the air supply, simply turn off the IV, venting the air remaining in the system. Since the air supply is not being removed from the marker under pressure, marker and tank are saved from wear and tear to ASA receiver threads, and damage to the bottle O-ring is eliminated. |
