GENERAL SAFETY INFORMATION

When properly installed and operated, the puriﬁer is designed

to purify ordinary compressed air to acceptable levels for

supplied air breathing systems. Appropriate safety precautions

must be observed to assure satisfactory service.

Consult factory for assistance and recommendation if puriﬁer

performance does not meet design speciﬁcations or when its

intended application is questionable.

1. LIMITATIONS ON USE OF SUPPLIED AIR RESPIRATORS

This equipment is for use with supplied air respirators.

Supplied air respirators should not be used in a hostile

environment (highly toxic or oxygen-deﬁcient) which

is immediately dangerous to life, or where the user

cannot escape without the aid of a respirator. Self-

contained breathing apparatus should be used for these

applications.

2. COMPRESSOR INTAKE

This equipment is for use with ordinary compressed air.

The compressor intake should be located to insure that

the air supply source is not oxygen-deﬁcient or subject to

unusual or gross contamination.

3. CARBON MONOXIDE DETECTION

This equipment is equipped with a humidity indicator

which gives advance warning of the impending expiration

of the catalyst used to eliminate carbon monoxide. This

indicator is not a carbon monoxide detecting device. A

compressor high temperature alarm or carbon monoxide

alarm (or both) should be provided. If a compressor high

temperature alarm only is used, frequent testing for

carbon monoxide concentration should be conducted.

4. LIMIT TO CARBON MONOXIDE REMOVAL

This equipment is provided with a catalyst which can

convert carbon monoxide to carbon dioxide. Its capacity

to decrease the concentration of carbon monoxide is

dependent on the air ﬂow rate and inlet concentration

of carbon monoxide. Although this catalyst is capable of

eliminating very high concentrations of carbon monoxide

(especially if of short term duration), carbon monoxide

inlet concentrations higher than 400 PPM v/v exceeds

the intended design speciﬁcations. Conversion of

concentrations higher than 400 PPM v/v will result in the

formation of excessive levels of carbon dioxide, and will

also cause an undesirably high air temperature rise.

5. PRESSURIZED DEVICES

This equipment is a pressure contain-

ing device. Observe normal precautions

when operating and servicing. Do not

exceed design limitations of pressure

and temperature as noted on unit serial number tag.

Always depressurize before servicing.

6. MAXIMUM WORKING PRESSURE

Do not exceed maximum compressed air pressure rating

as listed on dryer serial number tag.

1.0 INSTALLATION

1.1 Location

See schematic drawing, Figure 1. The puriﬁer is designed

speciﬁcally to treat compressed air for supplied breathing air

systems. To insure its functional operation, proper installation

is vital.

NOTE: Inlet and outlet isolation valves, drain and bleed valves

should be kept in closed position at all times when puriﬁer is

not in operation.

standard

C. Maximum operating temperature - 120°F (48.9°C)

D. Chemical attack - compressed air does not normally

contain contaminants which will adversely affect this

puriﬁer. However, aromatic and chlorinated hydrocarbons,

acids, bases and certain other chemicals can attack parts

of the ﬁlter assemblies and result in personal injury.

On questionable applications, the factory should be

consulted prior to installation or operation.

1.2 Mounting

A. Install so inlet and outlet connections are horizontal

and so that all cartridges are in a vertical position. Tipping

of cartridges from the vertical orientation can impede

drainage and/or reduce their efﬁciency. Allow a minimum

of 6" (152 mm) below the bottom edge of the convertor

case for cartridge replacement.

B. Bolt mounting bracket to wall or other support member

by means of (4) 5/16" fasteners.

3.0 OPERATION

A. The puriﬁer, when installed properly and operated within

its design limitations, will effectively purify compressed

air at system pressure so that it can be utilized, after

appropriate pressure reduction, with respirators, hoods

and similar breathing apparatus. It will remove liquid and

solid contaminants, odors and many toxic gases including

carbon monoxide. (Traces of hydrogen sulﬁde, sulfur di-

oxide, nitrogen dioxide, and miscellaneous organic gases

[not methane]) Treated air purity either meets or exceeds

OSHA standard for breathing air (See Table 2.) Although

the puriﬁer will eliminate the impurities commonly found

in compressed air, care should be exercised in the location

of the air compressor intake to avoid very high concen-

trations of impurities or unusual toxic contaminants from

being introduced into the system.

Occupational Safety and Health Regulations (1910.134d)

These regulations correspond to the Commodity

Speciﬁcation for Air, Compressed Gas Association Inc. - (CGA

Speciﬁcations G-7.1 Type 1, Grade D).

(1) The OSHA standard also states that compressed breathing air shall meet at leat the

requirements for Type-1 Grade 2 breathing aire described in ANSI/Compressed Gas

Association Commodity Speciﬁcation for Air ANSI/CGA G-7.1-1989.

(2) The CSA standard lists levels for a number of additional contaminants (methane. non-

methane hydrocarbons, nitrogen dioxide, nitrous oxide, halodenated hydrocarbons) and

includes by reference contaminants documented by the ACGIH for chemical substances and

physical agents in the workroom environment. The puriﬁer will remove only those gaseous

contaminants normally adsorbable by activated carbon.

* At rated conditions, the puriﬁer will reduce CO concentrations up to 400 PPM v/v to

below allowable limits.

** Since CO is converted to CO2 by the puriﬁer, high concentrations of CO in the system

and/or high concentrations of CO2 at the compressor intake could result in exceeding

allowable Co2 limits.

***Will remove gaseous hydrocarbons normally adsorbable by activated carbon.

B. Before and during operation, it is necessary to make

certain checks to insure satisfactory performance.

1. Check to see that lines downstream of the puriﬁer

are clean and free of materials which could show up

at the point of use of the air.

2. Check to see that the ﬁlter and convertor are

installed level. This is necessary to insure adequate

drainage.

3. Check the ﬂow, pressure, and temperature to insure

that the puriﬁer is being operated within design

limitations.

4. Check Indicator - DO NOT OPEN PURIFIER OUTLET

ISOLATION VALVE IF UPPER INDICATOR BAND IS YELLOW.

a. With outlet isolation valve closed and puriﬁer

pressurized, open indicator bleed valve until

upper indicator band turns green (approximately

5 minutes).

b. After upper indicator band has turned green,

close indicator bleed valve. (Note: A ﬁxed oriﬁce

will allow a small and continuous bleed of air to

ﬂow through the indicator.)

c. Open outlet isolation valve to place puriﬁer in

operation.

d. Low indicator band should gradually turn green

during operation.

e. Periodically (about every 30 minutes), check to

see that upper indicator band is green.

During this check, establish that indicator has

slight bleed ﬂow.

f. When upper indicator band turns yellow,

convertor cartridge should be replaced.

g. Lower indicator band will begin to turn yellow

if cartridge is not replaced. Cartridge must be

replaced before lower indicator band turns

completely yellow to avoid toxic levels of carbon

monoxide from passing through the puriﬁer.

4.0 MAINTENANCE

THE PURIFIER IS A PRESSURE CONTAINING

DEVICE. DEPRESSURIZE BEFORE SERVICING.

A. Periodically drain the two (2) vessels.

1. Filter - Before liquid level reaches cartridge bottom

cap.

2. Convertor - Each time cartridge is replaced or when

puriﬁer is taken out of operation.

4.1 Procedure for Filter Element Replacement

(See Section 5 for cartridge replacement procedure.)

A. Filter - When pressure drop across the ﬁlter exceeds

10 psi, or when pressure drop across the puriﬁer exceeds

15 psi.

1. The ﬁlter is supplied with a differential pressure

gauge. Pressure differential in excess of 10 psi

(0.7 kgf/cm

) - pressure indicator in red area -

indicates that the element should be replaced.

B. Convertor - When upper indicator band changes from

green to yellow.

C. Determine Cartridge life

1. Determine cartridge life at actual operating

conditions. At 80°F saturated inlet compressed air

temperature and 100 psig inlet pressure, a cartridge

will purify 5400 standard cubic feet of air.

2. Determine cartridge life at other conditions as

follows:

Step 1 - From Table 3, ﬁnd Maximum Theoretical Life

(MTL) in standard cubic feet (scf) that model 1901 can

handle at the pressure and dew point temperature at

the inlet to the puriﬁer.

Step 2 - If the inlet air is less than 100% saturated

(dew point temperature is less than sensible

temperature), adjust MTL for level of saturation.

Refer to Table 4 and ﬁnd the Saturated Air Correction

Factor (SACF) at the intersection of the dew point

and sensible temperatures corresponding to your

operating conditions.

Step 3 - Multiply MTL from step 1 by SACF to get

adjusted MTL.

Step 4 - To ﬁnd actual life in minutes, divide adjusted

life found in Step 3 by ﬂow requirements of

breathing apparatus.

EXAMPLE - Determine cartridge life at the following

conditions:

Flow requirement: 5 scfm

Inlet pressure: 100 psig

Inlet sensible temperature: 80°F

Inlet dew point temperature: 40°F

Step 1 - Find MTL from Table 3 at 40°F and 100 psig.

MTL = 22,470 scf.

Step 2 - Find SACF from Table 4 for 40°F dew point and

80°F sensible temperatures. SACF = 0.28

Step 3 - Find adjusted MTL by multiplying MTL by SACF.

22,470 x 0.28 = 6292

Step 4 - Find cartridge life in minutes by dividing

adjusted MTL from Step 3 by ﬂow requirement, 5 scfm.

6292÷5 =1258 minutes (21 hours)

6.0 GENERAL INFORMATION

1. When the puriﬁer is not in operation, all valves should be

closed, including the vessel drain cocks and the indicator

bleed valve. The convertor cartridge and indicator vessel

contain moisture sensitive materials.

NOTE: When indicator bleed valve is closed and system

is not in operation, an integral check valve will prevent

atmospheric air from entering and contaminating car-

tridges.

2. Replacement convertor cartridge should not be exposed

to moisture or high humidity. Do not unseal vapor bag

until immediately before installation and operation.

3. Replacement of the convertor cartridge, which is con-

sumable, is much more frequent (hours of use) than the

ﬁlter cartridge (months of use).

4. Consult factory for questionable applications or when in

doubt about intended usage.
