COMPONENT CONCEPT

Bullard's CC20E Series airline respirators consist of three components (Figure 1):
respirator hood assembly, breathing tube assembly and air supply hose. All components must be
present and properly assembled to constitute a complete CE approved respirator.
1. RESPIRATOR HOOD ASSEMBLY: Includes hood and headband suspension or hard hat.

20SICNE* (Tychem SL with taped seams)
20TICHE** (Tyvek QC)
* Optional Accessories: 20NC chinstrap, 20LCL lens cover
** Optional Accessories: ES42 chinstrap, 20LCL lens cover
2. BREATHING TUBE ASSEMBLY: Connects respirator hood to air supply hose by an
airflow control device and belt.
Breathing Tube Assemblies
V30E with 1/4" Industrial Interchange nipple
V33E with 1/4" brass Snaptite nipple
V39E with 9 mm European Interchange nipple
3. AIR SUPPLY HOSE: Connects
breathing tube to air source
supplying clean breathable air.
Hose for High Pressure Compressed
Air Source

3/8" I.D. Hose
E1010
E1020
Available in 10 and 20 meter lengths.
Note: When using V130-E breathing tube
assembly, use E10A Connection Kit to
connect to E10 hoses.
When using V133-E breathing tube assembly,
use E10B Connection Kit to connect to E10 hoses.
WARNING
Do not modify or alter this respirator in any manner.
Failure to use complete CE approved Bullard compo-
nents and replacement parts voids approval of entire
assembly.

Typical Breathing Air Source and Respirator Configurations

Bullard Air
Supply Hose
The point-of-attachment is the point at which the air supply hose connects to the air source. A pressure gauge attached
to the air source is used to monitor the pressure of air provided to the respirator wearer.

POINT-OF ATTACHMENT(POA)
Air pressure must be continually monitored at the point-of-attachment while operating this respi-
rator. A reliable air pressure gauge must be present to permit you to continually monitor the
pressure during actual respirator operation.
Failure to supply the minimum required pressure at the point-of-attachment for your hose
length and type will reduce airflow and may expose you to life-threatening conditions, diseases
or death.
The Breathing Air Pressure Table defines the air pressure ranges necessary to provide CC20E
Series respirators with a volume of air that falls within the required range.
Breathing Air Supply Hoses and Hose Fittings
CE approved Bullard air supply 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 (Figure 2).
When connecting lengths of E10 hose together, only use Bullard V11 hose-to-hose adaptors.
Secure connection(s) until wrench-tight and leak-free. Total connected hose length and number of
hoses MUST be within the ranges specified on the Breathing Air Pressure Table. The maximum
working pressure of E10 hoses is 500 psi (34 bar).
The breathing tube connection fitting MUST be secured to the belt that is supplied with this respi-
rator. Securing the air entry connection fitting helps prevent the air supply hose from snagging,
disconnecting or pulling the respirator hood off your head.
This table defines the air pressure ranges necessary to provide CC20E Series
Inner respirators with a volume of air that falls within the required range. The res-
Bib
pirator provides an air flow of 240-325 lpm to the user. The minimum length
of air supply hose is 10 meters, and the maximum length is 20 meters.

WARNING
Be certain your employer has deter-
mined that the breathing air source
provides clean breathable air. This
respirator must be supplied with clean
breathable air at all times.
Do not connect the respirator's air sup-
ply hose to nitrogen, oxygen, toxic
gases, inert gases or other unbreath-
able air sources. Check the air source
before using the respirator. Failure to
connect to the proper air source may
result in serious injury or death.
