North FRONTIER Series, Инструкция пользователя

Страница: 3 / 27

1.0 INTRODUCTION
These instructions are for the North Frontier Series Self-Contained Breathing Apparatus, an open cir-
cuit self-contained, pressure demand, compressed air breathing apparatus. The Frontier Series was
designed to provide essential respirable air and adequate respiratory protection in both toxic and
oxygen deficient atmospheres.
The North Frontier Series respirator consists of a cylinder, backframe and harness assembly, and full
facepiece or hood.
These respirators are approved by the National Institute of Occupational Safety and Health (NIOSH).
Positive pressure is maintained within the facepiece during use, thus providing the highest degree of
respiratory protection in irrespirable atmospheres by preventing any inward leakage. The Frontier
series includes SCBA units having a NIOSH 60 minute duration, units having a NIOSH 45 minute
duration, and units having a NIOSH 30 minute duration. The North Frontier Series are also certified
by NIOSH as Pressure Demand, Type C, Supplied Air Respirators when supplied with breathing air
from a remote source, and equipped with the appropriate quick-connect couplers.
