The SR 510, P100/HE particulate filter is of the mechanical type and designed for use in Sundström half masks,
full face masks Air Purifying Respirators (APR) and SR 500 Powered Air-Purifying Respirator (PAPR). The filter
provides protection against all types of particulate pollutants. The particulate filter can easily be combined
with chemical cartridges from the Sundström filter range in order to provide protection also against gases and
vapours, e.g. during spray painting. The particulate filter should be combined with pre-filter SR 221, which will
thereby extend the life of the particulate filter. The SR 500 PAPR should always be used with two particulate
filters or two combined filters consisting of chemical cartridge and particulate filters.
