Western/Scott Fetzer Digital VIPR Oxygen Tanks: Incorrect Pressure Gauge May Cause Oxygen
Western/Scott Fetzer recalls Digital VIPR oxygen tanks with faulty pressure gauges that may show higher pressure than actual, risking oxygen depletion without alarms during use.
Gauge malfunction: Digital gauge displays an incorrect tank pressure - displays pressure higher than actual tank pressure. This may lead to tank running out of oxygen during use without audible alarms, potentially leading to an out of oxygen event and no flow.
