Changing The Protective Elements - Sundstrom SR 900 APR Manuel De L'utilisateur

Filters – Filters clean the air of particles by capturing the solid particles and allowing breathable air to
enter the respirator. As the filter loads up with these particulates inhalation becomes uncomfortable.
When you detect increased inhalation resistance, leave the contaminated area and change the pre-filter,
or if necessary, the protective filter.
Pre-filter – This inexpensive nuisance pre-filter is used with a cartridge or P100 filter. When breathing
resistance increases change the pre-filter first. If the resistance does not drop change the protective element.

appropriate filter.
