MSA - M1 LGDV

The M1 lung governed demand valve is the successor of the popular AutoMAXX.

It has been completely redesigned, with the focus of fewer subassembly core parts lowering cost of ownership costs.

The flat design of the demand valve in combination with the G1 mask takes the wearer to a new level of comfort.

For enhanced safety the LGDV diaphragm and medium pressure hose are made of an innovative rubber material.

This material offers a better protection against chemical hazards vs silicone materials.

Improved ERGONOMICS

• Great freedom of movement thanks to low profile, rounded design and rotary movement supporting the natural head movements (left/right, up/down)
• Medium pressure hose is located close to the body to reduce risk of snagging hazards
• Large and well tactile operating elements (buttons)
• Long and short versions to accommodate various body heights or applications

Clear COMMUNICATION

• Significant reduction of breathing resistance and noise of the lung governed demand valve
• Enhanced speech intelligibility in combination with the G1 full face mask facilitates communication between firefighters

Enhanced HYGIENE

• Easy to clean and disinfect
• Simplified disassembly and assembly of components
• Machine washable (no disassembly required) when pressurised and using available washing adapters allowing for a continuous low air flow

Highest SAFETY STANDARDS

• Innovative rubber composition for mask, demand valve and SCBA pneumatics for increased chemical resistance
• BEST PROTECTION AGAINST PERMEATION (New diaphragm and medium pressure hose)

Easy SERVICE AND MAINTENANCE

• All components designed for longer life
• Easy to upgrade and service without special tools (less training requirements)
• Fewer subassembly core parts lowering cost of ownership
• Reduced maintenance costs due to possible extended service intervals
• Easy maintenance with available maintenance kits and basic overhaul kits
