This respirator meets the requirements of EN149:2001 + A1:2009 and should be used to protect the wearer from solid, oil and water based aerosols. The respirator can be used in concentrations of contaminants up to 10 times the Occupational Exposure Limits (OEL). Additionally, it has passed the optional Dolomite clogging test which offers excellent breathability in extremely dusty conditions with longer single shift use. The flexible edges conform to wearers’ facial features with a tight but comfortable seal, and the fold-out front allows for the same distance from the mouth as in traditional cone-style masks.
