General Information
Bullard's GR50 Series airline respirators, when
properly used, provide a continuous flow of air
from a remote air source, through a patented
air delivery system (U.S. Patent 4,484,575), to
the respirator wearer. GR50 Series respirators
offer protection from airborne contaminants that
are not immediately dangerous to life or health
(IDLH), or that do not exceed concentrations
allowed by applicable OSHA, MSHA, EPA, NIOSH
or ACGIH regulations and recommendations, or
any other applicable regulations.
GR50 Series airline respirators are approved by
NIOSH (TC-19C-329, Type C) to provide respiratory
protection in grinding operations and other
such general purpose applications. The GR50
is NOT intended for use in any abrasive
blasting operation.
GR50 Series respirators are compatible with
breathing air sources such as breathing air
compressors or Bullard Free-Air
offers the appropriate approved breathing
tube assembly and air supply hose to connect
the GR50 Series respirator to these breathing
air sources.
GR50 Series respirators are approved by
NIOSH for use with optional Bullard climate
control devices.
The GRH Hood of the GR50 Series can also be
configured for use with the Bullard EVA PAPR.
Refer to the EVA Manual for details.
