Operations
Breathing air Pressure
Air pressure must be continually monitored at the point-of-attachment while operating
this respirator. A reliable air pressure gauge must be present to permit you to
continually monitor the pressure during actual respirator operation.
The Breathing Air Pressure Table defines the air pressure ranges necessary to provide
CC20E
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 respirator. Securing the air entry connection fitting helps prevent the air supply hose
from snagging, disconnecting or pulling the respirator hood off your head.
CC20E Breathing air Pressure Table
This table defines the air pressure ranges necessary to provide
CC20E Series respirators with a volume of air that falls within the required range.
The respirator 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.

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.
Warning
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.
Warning
Be certain your employer has determined 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 supply
hose to nitrogen, oxygen, toxic gases, inert gases or other unbreathable 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.
