Manual No. 08850
2.4.2
The Clemco CPF Inline Particulate Filter with
regulator meets this requirement for a regulator and
gauge, provided inlet pressure does not exceed 150 psi.
DANGER
D
o not connect the climate control tube, 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
rupture under the high pressure of bottled air,
which could cause severe injury or death.
2.4.3
Use the following table to determine the
minimum pressure setting and maximum respirator hose
length that may be used with the climate control tube.
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 shown
provides a minimum of 7 cfm (cubic feet per minute) to
the respirator. The maximum allowable pressure for use
with the climate control tube is 100 psi.

The maximum overall hose length used with the climate
control tube is 200 feet when providing air to a respirator.
2.5 Dew
Point
2.5.1
If exhaust air reaches temperatures at or below
freezing, excess water vapor could freeze and cause the
air tube to ice-up. Compressed air should have excess
water vapor removed to attain a dew point below the
minimum anticipated temperature of the exhausting air.
Contact a compressed-air dryer distributor for dryer
recommendations.
2.6 Air
Volume
2.6.1
The climate control tube must be supplied with
20 cfm of Grade D breathing air at 90 to 100 psi.
WARNING
The compressor must provide adequate output
and the plumbing between the compressor and
the point of attaching the respirator hose must
have sufficient capacity to supply the volume of
air at the pressure required. Restricted air flow
will cause discomfort to the user, and may
result in ingress of hazardous and toxic dust,
subjecting the user to health and life
threatening toxic poisoning and long term
respiratory disease and death.
3.0 SET-UP
and
ADJUSTMENTS
3.1
Attach Breathing Tube Assembly
CAUTION
Note the directional flow arrows on the labels at
both ends of the breathing tube. The flow
arrows indicate the direction of air flow to the
helmet. Flow arrows must point toward the
helmet. Failure to properly attach the breathing
tube may damage the tube's acoustical foam,
which will block air flow, or it may increase
noise levels beyond OSHA limits.
3.1.1
The breathing tube has a clamped-on end and a
molded-on end. Attach the molded-on swivel connector
to the climate control tube’s outlet as shown in Figure 2.

3.1.2
Attach the clamped-on end to the threaded air
inlet fitting at the back of the helmet as shown in Figure
2. Do not over-tighten; hand-tight is sufficient.
3.1.3
Attach an approved Clemco respirator hose to
the quick-disconnect nipple.
