POWERED AIR PURIFYING RESPIRATOR

2-12. Maintenance And Storage

Replace damaged or dirty air filters. Do not wash filters, clean with compressed air, or

reuse dirty air filters.

Never use solvents or abrasive cleaning solutions to clean the respirator. Keep water and

other fluids out of blower assembly.

Maintain accurate records of filter replacement and respirator maintenance.

For best performance clean the equipment after each use. Use a soft cloth

dampened with a mild soap and water solution to wipe all external surfaces

clean. Allow to air dry.

Product usage, workplace contamination levels, and other factors affect the life

of the filter elements. Replace filter elements if air flow is reduced due to a dirty

filter (see Section 2-4) and according to the filter change schedule established

by your Safety Director and an Industrial Hygienist.

Inspect connecting hose and replace if damaged or if inside of tube is dirty.

If the respirator will not be used for an extended period, remove the filter and

battery and store them in a clean, dry, cool place free of solvent-based vapors.
