MSA AutoMaXX-AS-B Lung Demand Valve

This particular AutoMaXX lung demand valve is for positive pressure use and features a MaXX plug connector (AS).  Additional features include a by-pass valve which provides an adjustable, constant air stream.

The AutoMaXX range of lung demand valves (LDV) is ideal for tough conditions.  They give a sensitive response to individual user’s breathing and have a special design to allow easy use.

The housing is toughened so it is protected from any accidental knocks and doesn’t get tangled during use.  Any buttons on the AutoMaXX LDV are large and well-positioned so users can easily access them, even when wearing gloves.

The AS-type LDVs have the function of automatically shutting down positive pressure when they are removed from a face mask.
