Description

• The Half mask VALUAIR medium is designed to work when external concentration allows it.
• The type of protection depends on the cartridges connected, gases, particles, or combined.
• The threshold is depending on a theoretical calculation, based on the facial leakage and the efficiency of the adapted canister.
• The APF is evaluated from 12 to 50.
• It allows the use of the Half mask from an external concentration between 12 times to 50 times the Occupational Exposure Limit.
• The half-mask VALUAIR medium can be used only with certified T SERIES cartridges (following the standard EN 141, EN 143).
