Gross dimensions
The mask contains passive venting to protect against
rebreathing. As a result of manufacturing variations, the vent
flow rate may vary.
Physical dead space is the empty volume of the mask to the
end of the swivel. Using the large cushions it is 123 mL.

DECLARED DUAL-NUMBER NOISE EMISSION VALUES in
accordance with ISO 4871. The A-weighted sound power
level of the mask is 21 dBA, with uncertainty of 3 dBA. The
A-weighted sound pressure level of the mask at a distance
of 1 m is 13 dBA, with uncertainty of 3 dBA.
