NIOSH-approved Bullard air s u p p l y
hose(s) MUST be used between the
breathing tube connection fitting on
the wearer’s belt and the point-of-
attachment to the air supply (see
Figure 3).
NIOSH-approved Bullard quick-dis-
connect fittings MUST be used to con-
nect V20 hose lengths together.
When connecting lengths of V10
hose, only use Bullard V11 hose-t o -
hose adaptors. Secure connection(s)
until wrench tight and leak free. Total
connected hose length and number of
hose lengths MUST be within the
ranges specified on the Breathing Air
Pressure Table below and the respira-
tor's NIOSH approval label (see page
1).
The breathing tube connection fitting
MUST be secured to the belt that is
supplied with this respirator. Securing
the breathing tube connection fitting
helps prevent the air supply hose
from snagging, disconnecting or pulling
the respirator helmet off your head.
Breathing Air Pressure Ta b l e
Adjust breathable airflow at the point-of-attachment to a pressure that falls within the range required for the equip-
ment combination of your respirator.
