Bullard’s 88E Series airline respirators, when properly used, provide a continuous flow of air

from a remote air source to the respirator wearer. 88E Series respirators offer protection from

airborne contaminants that are not immediately dangerous to life or health or that do not exceed

concentrations allowed by applicable regulations and recommendations. If you have any ques-

tions concerning the use of this respirator, or if you are not sure whether the atmosphere you

are working in is immediately dangerous to your life or health, ask your employer. All instructions

for the use and care of this product should be supplied to you by your employer as recommended

by the manufacturer.
88E Series airline respirators are approved to provide respiratory protection in general purpose

applications including heavy and light-duty abrasive blasting. The cape is designed to protect the

worker’s body from abrasive rebound.
This respirator, when properly fitted and used, significantly reduces, but does not completely

eliminate, the breathing of contaminants by the respirator wearer. When properly fitted, used

and maintained, it will provide protection up to 1000x occupational exposure limit. (Check regula-

tory requirements to determine exposure limits.)
Improper respirator use may damage your health and/or cause your death. Improper use may

also cause certain life-threatening delayed lung diseases such as silicosis or pneumoconiosis.
This respirator is not suitable for use in flammable atmospheres and is not designed for use in

exceptionally low or high temperatures where moisture in the air could freeze or the worker

could be at risk for heat exhaustion. The air supply moisture content should be controlled to avoid

freezing the apparatus when used at temperatures below 4° C.
FACE AND EYES

The respirator’s inner lens provides protection to EN 166 (low energy impact). Wear appropriate

safety glasses or goggles if higher protection levels are required.
HEAD

This respirator is designed to provide limited head protection by reducing the force of falling

objects striking the top of the helmet.

COMPONENT CONCEPT

Bullard’s 88E Series airline respirators consist of three

components (Figure 1): respirator helmet 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 HELMET ASSEMBLY: Includes inner shell,

headband suspension, chin strap and cape.

2. BREATHING TUBE ASSEMBLY: Connects respirator

helmet to air supply hose by an adjustable airflow control

device (F100E) and belt.

3. AIR SUPPLY HOSE: Connects breathing tube to air source

supplying clean breathable air.

Low Flow Indicator

The low flow indicator is located on the F100E flow control device. The indicator must be checked

periodically when the respirator is in use. During use, the needle on the low flow indicator should

point into the green section of the gauge indicating proper flow levels. If the needle dips into the

red section, leave the work area immediately as you are receiving less than the required air flow

for safe operation.

WARNING

The Low Flow indicator must be checked periodically while the respirator is in use.

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.

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.

Breathing Air Pressure

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 3).

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 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 helmet off your head.

Before you can size the headband suspension, the cape and headband must be removed from

the helmet using the following steps:

WARNING

Do not modify or alter this respirator in any manner. Failure

to use complete CE approved Bullard components and

replacement parts voids approval of entire assembly.

WARNING

At very high work rates, the pressure in the hood

may become negative at peak inhalation flow. To

minimize this potential, utilize the maximum air pres-

sure specified in the Breathing Air Pressure Table

and adjust flow control valve to maximum flow.

Breathing Air Pressure Table

This table defines the air pressure ranges necessary to provide 88E Series respirators with a volume of air that falls within the required range.

The respirator provides an air flow of 210-345 lpm to the user. The minimum length of air supply hose is 10 meters, and the maximum length is

20 meters.
