DANGER: Ventilation rates up to 40 l/min are referenced as "Nor-
mal swimming" and rates of 40 l/min and above are referenced as
‘Hard swimming’. Under strenuous conditions however consump-
tion rates may be significantly higher. Regardless of conditions or
readings on the computer, the scrubber should NEVER be used for
more than 2 hours.
! WARNING: These tests were conducted using Hollis approved
absorbent, and durations can only be duplicated using such. DO
NOT use any other type of absorbent with the EXPLORER. Safety
data on absorbent products can be found at their respective brand
websites.
Tests conclude that depth (gas density), temperature, and CO
2
generation
all massively affect absorbent duration. The EXPLORER employs a highly
efficient axial canister design which not only offers greatly extended dura-
tions when compared to other designs employing a similar absorbent load,
but it is less affected by the commonly experienced high loss of efficiency
associated with increased depth.
