Manual No. 23930
4.2.3 Cylinders must be equipped with a properly
maintained pressure reducing valve that reduces
pressure to the approved pressure range of the
respirator. See 4.4.
4.3 Breathing-Air from Compressors
4.3.1 The employer shall ensure that air from
compressors used to supply breathing air to respirators
meets the requirements in 29 CFR 1910.134.(i)(5).
4.3.2 Precautions must be taken to prevent
contaminants from entering through the compressor
intake: Ref. 29 CFR 1910.134.(i)(5)(i). The compressor
inlet must be located away from all sources of toxic
contaminants including carbon monoxide, which is found
in engine exhaust (including the exhaust from the
compressor’s engine), and in any form of combustion.
No vehicles should be allowed near the compressor
intake. Contaminants can enter respiratory equipment
through the compressor air inlet. This inlet must not be
located near any exhaust system outlet, ventilation flue,
or source of fumes or particles of any kind.
4.3.3 The compressed-air supply system must be
equipped with suitable in-line air-purifying sorbent beds
and filters, and be maintained to further ensure
breathing air quality: 29 CFR 1910.134 (iii).
4.3.4 If the breathing-air supply is from a non-oil-
lubricated compressor, the employer shall ensure that
the carbon monoxide levels in the breathing air do not
exceed 10 ppm: 29 CFR 1910.134 (i)(6).
4.3.5 If an oil-lubricated compressor is used, the
employer shall use a high-temperature alarm or carbon
monoxide (CO) alarm, or both, to monitor carbon
monoxide levels. If only high-temperature alarms are
used, the air supply shall be monitored at intervals
sufficient to prevent carbon monoxide in the breathing
air from exceeding 10 ppm: 29 CFR 1910.134 (i)(7).
S-Special or Critical User’s Instructions
4.4 Air Volume and Pressure
4.4.1 Operating Pressure
4.4.1.1 HP respirators operate within the pressure
range of 65 and 100 psi (pounds per square inch), as
shown in the table in this section. Maintaining the correct
operating pressure at the point of attachment ensures
the correct air flow to the respirator.
4.4.1.2 The Clemco CPF Inline Particulate Filter with
regulator meets this requirement for a regulator and
gauge, provided the inlet pressure does not exceed 150
psi. See typical installation, Figure 1.
DANGER
Do not connect the Apollo Respirator or CPF
Filter, or any other regulator or filter, to bottled-
air that does not have a pressure reducing
valve that reduces pressure to the maximum
operating pressure of the respirator of filter it
services. Failure to comply with this warning
will cause devices rated at lower pressures to
explode under the high pressure of bottled-air,
and cause severe injury or death.
4.4.1.3 Use the following table to determine the
minimum pressure settings and maximum respirator
hose length, based on the air-control device as shown in
Section 2.1.1. Adjust the pressure with the respirator
hose and respirator attached. If the regulator is adjusted
with static pressure (no air flow), pressure may drop
below the required pressure when the respirator is
connected, and may result in low air flow. Setting the
pressure as instructed will provide a minimum of 7 cfm to
the respirator.

4.4.2 Air Volume
4.4.2.1 When using a CFC constant-flow connector or
ACV air valve, the respirator must be supplied with 15
cfm (cubic feet per minute) of Grade D breathing air at
