The QAF filter does not remove methane, carbon monoxide, carbon dioxide or other
toxic gases and fumes!
(1) At start up and during normal operation, the differential pressure indicator will be yellow; it turns red
when the pressure drop of the filter increases.
(2) The differential pressure gauge indicates the pressure drop by a color scale which gradually changes
from yellow to orange to red which corresponds to an absolute scale of 0 to 750 mbar.
