GR50 Series Airline
Respirator User Manual
Parts and Accessories for GR50 Series Airline Respirators
GR50 Series airline respirators consist of four components: respirator hood, headband suspension
or head protection, breathing tube assembly and air supply hose. There are options for some
components to fit customer specifications. All four components must be present and properly
assembled, including a Bullard air supply hose, to constitute a complete NIOSH-approved respirator
(Approval No. TC-19C-329, Type C).
NOTE
All climate control devices require use of the
20BT breathing tube to constitute complete
breathing tube assemblies. Breathing tube must
be purchased separately.

Hard Hat
Inspection:
Inspect the hard hat shell for
nicks, gouges, cracks and any damage due to
impact, rough treatment or wear.
Remove the headband suspension and optional
chin strap from the hard hat. Inspect the head-
band for cracks, frayed or cut crown straps,
torn headband and size adjustment slots, loss of
pliability or other signs of excessive wear. Check
the chin strap for loss of elasticity, cuts and
cracked hanger clips.
If damage is detected, replace part(s) immedi-
ately with Bullard replacement parts or remove
the respirator from service.
Cleaning:
The hard hat shell, headband suspen-
sion and optional chin strap should be hand-
sponged with warm water and mild detergent,
rinsed and air-dried. After cleaning, and before
reassembling, once again carefully inspect parts
for signs of damage.
Breathing Tube Assembly
Inspection:
Inspect the vinyl breathing tube
for tears, cracks, holes or excessive wear that
might reduce the degree of protection originally
provided. Be sure the quick-disconnect fitting is
screwed tightly into the breathing tube so no air
can escape.
Be sure the airflow control device is
screwed tightly into the breathing tube so air
cannot escape.
If any signs of excessive wear are present,
replace the breathing tube assembly immedi-
ately or remove the respirator from service.
Cleaning:
To clean the breathing tube assem-
bly, hand-sponge with warm water and mild
detergent, rinse and air-dry. Do not get water
inside the flow control device or breathing tube.
After cleaning, once again carefully inspect
breathing tube for signs of damage.
�
WARNING
Do not cut or remove foam that is inside the
breathing tube. The foam helps reduce the noise
level of the incoming air supply. It does not filter
or purify your breathing air. NIOSH has approved
this respirator with the foam in place.
Air Supply Hoses
Inspection:
The starter and extension hose(s)
should be inspected closely for abrasions,
corrosion, cuts, cracks and blistering. Be sure
the hose fittings are crimped tightly to the
hose so that no air can escape. Make sure the
hose has not been kinked or crushed by any
equipment that may have rolled over it.
If any of the above signs are present or any
other signs of excessive wear are detected,
replace the hose(s) immediately or remove the
respirator from service.
Cleaning:
The air supply hose(s) should be
hand-sponged with warm water and mild
detergent, rinsed and air-dried. Do not get water
inside the air supply hose. After cleaning, once
again carefully inspect air supply hose(s) for
signs of damage.
�
WARNING
Only use Bullard hoses that are NIOSH-approved
for use with this respirator. Other hoses could
reduce airflow and protection, and expose the
wearer to life-threatening conditions.
Storage
After reusable respirator components have been
cleaned and inspected, place them in a plastic
bag or an airtight container.
Store the respirator and parts where they will
be protected from contamination, distortion
and damage from elements such as dust, direct
sunlight, heat, extreme cold, excessive moisture
and harmful chemicals.
