* Assumes that no air is being dumped from the pressure relief valve and that pump’s drive-air pressure is maintained at 85 psig.
** It should be noted that the minimum air flow required for each tight-fitting, mask-style respirator is four (4) cfm. A minimum airflow of six (6) cfm is required for each
hood-style respirator.
The ratings which appear here, therefore, are conservative, but reflect Bullard Company’s position that worker respiratory protection is enhanced when air flow available to
the respirator wearer is above the NIOSH required minimums.
