OPERATIONAL INSTRUCTIONS
OPERATOR SAFETY EQUIPMENT
•Blast operators and others working in the vicinity of
abrasive blasting must always wear properly-
maintained, NIOSH-approved, respiratory protection
appropriate for the job site hazards.
•DO NOT USE abrasives containing more than one
percent crystalline (free) silica. Ref. NIOSH Alert
#92-102
•Inhalation of toxic dust (crystalline silica, asbestos,
lead paint and other toxins) can lead to serious or
fatal disease (silicosis, asbestosis, lead or other
poisoning).
•ALWAYS wear NIOSH-approved supplied-air respirators
as required by OSHA, in the presence of any dust including,
but not limited to, handling or loading abrasive; blasting or
working in the vicinity of blast jobs; and cleanup of expended
abrasive. Prior to removing respirator, an air monitoring
WARNING
WARNING
I

PREFACE
instrument should be used to determine when surrounding
atmosphere is clear of dust and safe to breathe.
•NIOSH-approved, supplied-air respirators are to be worn
ONLY in atmospheres:
• NOT IMMEDIATELY dangerous to life or health and,
• from which a user can escape WITHOUT using the
respirator.
•Clemco supplied-air respirators DO NOT REMOVE OR
PROTECT AGAINST CARBON MONOXIDE (CO) OR ANY
OTHER TOXIC GAS. Carbon monoxide and toxic gas removal
and/or monitoring device must be used in conjunction with
respirator to insure safe breathing air.
•Air supplied to respirator MUST BE AT LEAST GRADE D
QUALITY as described in Compressed Gas Association
Commodity Specification G-7.1, and as specified by OSHA
Regulation 1910.139 (d).
•ALWAYS locate compressors to prevent contaminated air
(such as CO from engine exhaust) from entering the air intake
system. A suitable in-line air purifying sorbent bed and filter or
CO Monitor should be installed to assure breathing air quality.
•ALWAYS use a NIOSH-approved breathing air hose to
connect an appropriate air filter to the respirator. Use of a non-
approved air hose can subject the operator to illness caused
by the release of chemical agents used in the manufacture of
non-approved breathing air hose.
•ALWAYS check to make sure air filter and respirator
system hoses are NOT CONNECTED to in-plant lines that
contain nitrogen, acetylene or any other non-breathable gas.
NEVER use oxygen with air line respirators. NEVER modify air
line connections to accommodate air filter/respirator breathing
hose WITHOUT FIRST testing content of the air line. FAILURE
TO TEST THE AIR LINE MAY RESULT IN DEATH TO THE
RESPIRATOR USER.
•Respirator lenses are designed to protect against
rebounding abrasive. They do not protect against flying
objects, glare, liquids, radiation or high speed heavy materials.
Substitute lenses from sources other than the original
respirator manufacturer will void NIOSH-approval of this
respirator.
BLAST MACHINES AND REMOTE CONTROLS
•ALWAYS equip abrasive blast machines with
remote controls.
•Abrasive blast machine operators must wear NIOSH-
approved supplied-air respirators (ref: OSHA
regulations 1910.94, 1910.132, 1910.139 and
1910.244).
•NEVER modify OR substitute remote control parts. Parts
from different manufacturers are NOT compatible with Clemco
equipment. If controls are altered, involuntary activation, which
may cause serious injury, can occur.
•Inspect the air control orifice DAILY for cleanliness.
NEVER use welding hose in place of twinline control hose. The
internal diameter and rubber composition are UNSAFE for
remote control use.
•UNLESS OTHERWISE SPECIFIED, maximum working
pressure of blast machines and related components MUST
NOT exceed National Board approved 125 psig (8.5 BAR).
•NEVER weld on blast machine. Welding may affect
dimensional integrity of steel wall and WILL VOID National
Board approval.
•Point nozzle ONLY at structure being blasted. High
velocity abrasive particles WILL inflict serious injury. Keep
unprotected workers OUT of blast area.
•NEVER attempt to manually move blast machine when it
contains abrasive. EMPTY machines, up to 6 cu. ft.(270kg)
capacity, are designed to be moved:
• on flat, smooth surfaces by AT LEAST two people;
• with the Clemco "Mule"; or
• with other specially designed machine moving devices.
•Larger empty blast machines or ANY blast machine
containing abrasive MUST be transported by mechanical lifting
equipment.
AIR HOSE, BLAST HOSE, COUPLINGS, AND NOZZLE HOLDERS
•Air hose, air hose fittings and connectors at compressors
and blast machines MUST be FOUR times the size of the
nozzle orifice. Air hose lengths MUST be kept as short as
possible AND in a straight line. Inspect DAILY and repair
leakage IMMEDIATELY.
•Blast hose inside diameter MUST be THREE to FOUR
times the size of the nozzle orifice. AVOID sharp bends that
wear out hose rapidly. Use SHORTEST hose lengths possible
to reduce pressure loss. Check blast hose DAILY for soft
spots. Repair or replace IMMEDIATELY.
•ALWAYS cut loose hose ends square when installing hose
couplings and nozzle holders to allow uniform fit of hose to
coupling shoulder. NEVER install couplings or nozzle holders
that DO NOT provide a TIGHT fit on hose. ALWAYS use
manufacturers recommended coupling screws.
•Replace coupling gaskets FREQUENTLY to prevent
leakage. Abrasive leakage can result in dangerous coupling
failure. ALL gaskets MUST be checked SEVERAL times during
a working day for wear, distortion and softness.
•Install safety pins at EVERY coupling connection to
prevent accidental disengagement during hose movement.
•ALWAYS attach safety cables at ALL air hose AND blast
hose coupling connections. Cables relieve tension on hose and
control whipping action in the event of a coupling blow-out.

1.0 INTRODUCTION
1.1 Scope of Manual
1.1.1 These instructions cover setup, operation,
maintenance, replacement parts, and important warnings
to safely operate the Clemco CPF Particulate Air Filter.
1.1.2 These instructions also contain important
information required for safe operation of the filter. All
respirator users and maintenance personnel must be
trained to safely operate and maintain the filter and
respirators. The respirator users and all personnel
involved with the breathing air process must be able to
identify potential hazards associated with breathing
compressed air. Before using the filter, all personnel
involved with the operation must read this entire manual,
including the orange cover, plus the respirator manuals
and all accessory manuals.
1.2 Safety Alerts
1.2.1 Clemco uses safety alert signal words, based on
ANSI Z535.4-1998, to alert the user of a potentially
hazardous situation that may be encountered while
operating this equipment. ANSI’s definitions of the signal
words are as follows:
This is the safety alert symbol. It is used
to alert the user of this equipment of
potential personal injury hazards.
Obey all safety messages that follow this
symbol to avoid possible injury or death.
CAUTION
Caution used without the safety alert symbol
indicates a potentially hazardous situation
which, if not avoided, may result in property
damage.
CAUTION
Caution indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury.
WARNING
Warning indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
DANGER
Danger indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.
1.3 OSHA Compliance
1.3.1 When CPF Filters are used with a NIOSH-
approved supplied-air respirator, meets OSHA regulations
1910.94(a)(6)and 1910.134 (i)(5)(iii), requiring air for
abrasive blasting respirators shall be free of harmful
quantities of dust, mists, and noxious odors. CPF filters
provide a pressure-reducing valve to lower the pressure to
meet the pressure requirements of the respirator,
providing that the filter’s inlet pressure does not exceed
150 psi.
1.3.2 Important information concerning the quality of
compressed air, the use of respirators, and exposure to
hazardous dust is found in OSHA regulations 29 CFR
1910.94, 29 CFR 1910.134 and 29 CFR 1910.1000.
Note regulations 29 CFR 1910.94 and 29CFR1910.134
require that abrasive blasting respirators meet the
requirements for supplied-air quality. For total
compliance, the system must also include a NIOSH-
approved supplied-air respirator.
1.3.3 All supplied-air respirators using non-oil-
lubricated or oil-lubricated compressors shall have a
carbon monoxide monitor to meet the requirements of
CFR 1910.134 (i)(6) and (i)(7).
1.3.4 OSHA regulations 29 CFR1910 and
29CFR1926 require that respirator air line couplers be
incompatible with air lines for non-respirable use. This
prevents inadvertent servicing of respirators with non-
respirable gases or oxygen. It is the employer's or facility
owner's responsibility to comply with the regulation.
1.3.5 The CPF filter is to be used with NIOSH-
approved supplied-air respirators in atmospheres not
immediately dangerous to life or health (IDLH), with as
least 19.5% oxygen, and from which a user can escape
without the use of the respirator.
1.3.6 Breathing air used to supply the filter must be
respirable breathing air and contain no less than 19.5
volume-percent of oxygen. Breathing air shall also meet
the requirements for Grade D or higher quality, as
described in Compressed Gas Association Commodity
Specification pamphlet G-7.1., titled Commodity
Specification For Air, published by Compressed Gas
Association Inc., Chantilly, VA. CGA Website is
cganet.com

CPF 20/80 PARTICULATE AIR FILTER Page 2

WARNING
Respirator(s) must be supplied with at least
Grade "D" quality respirable air, containing no
less than 19.5 volume-percent of oxygen.
Breathing air requirements are described in
Compressed Gas Association, G-7.1.,
Commodity Specification For Air, published by
Compressed Gas Association Inc., Chantilly,
VA. CGA Website is cganet.com. If air quality is
unknown, consult a safety professional and/or
industrial hygienist. Poor quality air will cause
serious respiratory injury or death to the user.
1.4 General Description
1.4.1 The CPF is a particulate filter, which removes
mists (including oil mist), water vapor and particulate
matter, down to 0.5 micron in size from breathing air
supplied by a breathing-air compressor. The CPF Filter
does not detect or remove carbon monoxide (CO) or
any other toxic gases. Filter effectiveness and cartridge
life will be reduced considerably if the supplied air is
heavily contaminated with particulate matter or moisture.
1.4.2 The main components of the filters are shown in
Figure 1. The CPF-20 is equipped with an outlet that
supplies filtered air to one or two supplied-air respirators.
The CPF-80 has four outlets, and will accommodate up
to four supplied-air respirators with total air requirement
not to exceed 100 cfm.
WARNING
Respirators are NIOSH-approved to operate
within specific pressure ranges. When
connecting multiple respirators, make sure that
all respirators are approved to operate within
the same pressure range. Operating the
respirator outside of the approved pressure
range will increase or restrict airflow beyond
permissible limits.
1.4.3 Compressed air enters the filter through either of
the two side inlet ports. Moisture condensing inside the
filter is drained through the petcock at the bottom of the
filter body. Air is forced through a replaceable filter
cartridge, which contains several filtering materials,
which traps particulates.
1.4.4 Outlet pressure is adjusted by the knob on the
pressure regulator. Both filters are equipped with a
pressure relief valve. The relief valve is an audible signal
that pressure is exceedingly high.

WARNING
Outlet fittings (the point of attachment) and
respirator hose must be NIOSH-approved for
use with the respirator. Use of non-approved
fittings and hose will void the NIOSH approval
of the respirator, and could restrict air flow. Do
not use any bushings or reducers that reduce
the internal diameter of the plumbing. Reduced
air flow may result in ingress of hazardous
dust, fumes or gases, exposing the user to
immediate health risk and subsequent
respiratory disease and possible death.
2.2.4 Attach the 3/8" x 2" nipple (3/8" hex nipple on
CPF-80) to the regulator inlet port, and tighten the
regulator assembly into the 3/8" port on the filter cap.
Arrange the assembly so the outlet ports of the tee are
accessible, and the regulator control knob is convenient
to adjust.
2.2.5 Screw the pressure gauge into one of the
regulator side ports, and position it so the pressure can
be easily monitored.
2.2.6 Screw the relief valve into the remaining port on
the cap.
3.0 AIR SUPPLY
WARNING
Air supply to this filter is critical to the safety of
the user. Read this section and the respirator
manuals carefully. Poor quality air will cause
serious respiratory injury or death to the user.
(See Toxic Dust Poisoning Warning on page 1.)
3.1 Air Quality
3.1.2 Air supplied to the filter’s inlet must be at least
Grade "D" quality. Special care must also be taken to
avoid accidental connection to any other gas lines, such
as, oxygen, acetylene, or nitrogen.
DANGER
CPF Filters are particulate filters. They do not
remove carbon monoxide or other toxic gases.
Air supplied to the filter inlet must be at least
Grade "D" quality. Never connect the CPF Filter
or any breathing-air line to an air source that has
not been tested for gas contamination. The
presence of unacceptable levels of carbon
monoxide (CO) or other gases, or oxygen
deficiency in the breathing air will cause death to
the user.
WARNING
OSHA regulations 29 CFR 1910 and 29 CFR
1926 require that respirator air line couplers be
incompatible with air lines for non-respirable
use. This incompatibility prevents inadvertent
supply of respirators with potentially
hazardous, non-respirable gases, or oxygen. It
is the employer's or facility owner's
responsibility to comply with the regulations.
3.1.3 Prior to using the filter and respirator, read the
owner's manual and all instructions, labels, and warnings
related to the compressed air source. Take special care to
abide by all warnings from the compressor manufacturer
regarding compressor use.
3.1.4 A breathing-air-type-compressor must be used.
The compressor must be equipped with necessary safety
and monitoring devices, plus suitable in-line air filters and
purifying equipment to assure breathing-air quality.
[Reference OSHA Regulation 1910.134 (d)].
3.1.5 If an oil-lubricated compressor is used, it must be
equipped with a high-temperature alarm or carbon
monoxide (CO) alarm, or both. If only a high-temperature
alarm is used, the air from the compressor must be tested
frequently for the presence of carbon monoxide.
[Reference OSHA Regulation 1910.134 (d)].
3.1.6 Regardless of the air compressor type,
precautions must be taken to prevent contaminants from
entering through the compressor intake. The compressor
inlet must be located away from all sources of toxic
contaminants including carbon monoxide, which is found
in engine exhaust, 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.

3.1.7 The preceding precautions also apply to portable
compressors. In addition, in the case of engine-driven
compressors, precautions must be taken to prevent
engine exhaust gases from entering the air intake of the
compressor. Compressor engine exhaust should be piped
to a location safely downwind from the compressor air
intake. Compressors vary in design and operation;
therefore, it is important that users carefully read the
manufacturer's operation and maintenance instructions
before making modifications.
3.1.8 It is the owner's and user's responsibility to make
sure the air supply is safe to breathe. The air supply
includes the compressor, carbon monoxide alarms, and
shutdown devices. An overheated compressor, or one that
is in poor mechanical condition, may produce carbon
monoxide. A carbon monoxide removal or conversion
system may also be used to ensure breathing-air quality.
The maximum allowable level of carbon monoxide in
Grade D breathing air is 10 ppm (parts per million).
3.2 Air Pressure (Outlet Pressure)
3.2.1 Outlet pressure must be set to the pressure for
which the respirator(s) is designed. Refer to the
respirator owner’s manual to find the approved pressure
setting. All respirators connected to the filter must be
approved to operate within the same pressure range.
WARNING
Failure to maintain the minimum pressure at the
CPF filter outlet (point of attachment) may
reduce air flow below the minimum flow
required by OSHA. Reduced air flow may result
in ingress of hazardous toxic dust, subjecting
the user to immediate health and life
threatening poisoning and subsequent
respiratory disease.
4.0 SETUP
NOTE: The filter must be setup and placed in an area
that permits monitoring of the outlet pressure,
access to the drain, and removal of the cap for filter
cartridge replacement.
4.1 Breathing-Air Connections
4.1.1 Filters can be configured for either left or right
hand inlet. If it is more convenient to have the air inlet on
the opposite side, swap the plug and inlet connector.
This is usually required only with fixed installations.
4.1.2 The following instructions explain air
connections using hose as the air supply line; hard
piping may be used in place of hose. If the filter is hard-
piped, place an isolation valve in the piping to enable
depressurization for service.
4.1.3 Connect an air fitting that is compatible with the
air supply hose, from an air source that meets OSHA
requirements for respirable air, to either of the inlet ports
on the side of the filter. The port’s thread size is 1" NPT.
4.1.4 Connect a 3/4" ID or larger air hose, from a
respirable air source to the inlet fitting. Maximum inlet
pressure is 150 psi.
DANGER
Do not connect the CPF Filter to bottled air or
any other air source that does not have a
pressure-reducing valve that lowers pressure to
maximum of 150 psi. Failure to comply with this
warning will cause the CPF filter to explode
under the high pressure of bottled air, and
could cause severe injury or death.
5.0 ADJUSTMENTS
5.1 Outlet Pressure
5.1.1 Outlet pressure must be set to the pressure for
which the respirator(s) is approved. The respirator’s
approved pressure may be found in the respirator’s
owner’s manual. All respirators connected to a filter must
be approved to operate within the same pressure range.
5.1.2 Adjust pressure with respirators attached and
prior to donning the respirator.
5.1.3 To adjust pressure: pull the regulator knob out,
and turn clockwise to increase pressure or counter-
clockwise to decrease. Pressure will register on the
gauge. Once operating pressure is set, push the knob in
to lock.
6.0 MAINTENANCE
6.1 Draining
6.1.1 Drain moisture from the filter every four hours.
More frequent draining may be required in humid
environments. The drain petcock is located on the
bottom of the filter body.

6.2 Filter Cartridge Replacement
6.2.1 Never attempt to clean the filter cartridge.
Replace the filter cartridge at least every three months.
Replace it sooner if:
•Users detect any objectionable odors.
•The filter begins to pass moisture through the
outlets.
•The outlet pressure nears the lowest pressure for
which the respirators are approved.
6.2.2 Before replacing the cartridge, always drain the
filter through the petcock and leave the drain open. Shut
off the compressed air supply to the filter. Make sure
petcock no longer exhausts air and that the pressure
gauge reads zero.
6.2.3 Remove the four nuts that hold cap in place and
lift the cap. Install the new cartridge with the arrow
pointing up. Inspect the cap gasket and o-ring and
replace them as needed.
6.3 Cartridge Replacement Record
6.3.1 Use the chart in Figure 4 to maintain an
accurate record of filter cartridge replacement dates.
Replace the filter cartridge at least every three months
with a genuine Clemco replacement filter cartridge.
