1. SR 500 Fan Unit General Description
The SR 500 is a battery powered fan unit that,
together with filters/cartridge and an approved
respirator inlet covering (facepiece or headgear) is a
NIOSH 42CFR84 approved powered air-purifying
respirator (PAPR).
The fan unit equipped with filters/cartridge supplies
filtered air at above-atmospheric pressure through a
breathing hose to the facepiece or headgear to
provide respiratory protection against certain
particulates, organic vapors, acid gases and other
inorganic gases. The generated air pressure prevents
pollutants from the surroundings from penetrating into
the inlet coverings.
The SR 500 can be used as an alternative to filter
respirators in all situations for which these are
recommended. This applies particularly to work that is
hard, warm or of long-duration. If you feel uncertain
about the selection and care of the equipment,
consult your work supervisor or get in touch with
Sundström Technical Support.
IMPORTANT: THIS RESPIRATOR IS INTENDED
TO BE USED ONLY IN CONJUNCTION WITH AN
ORGANIZED RESPIRATORY PROTECTION
