FUNCTION: The Frigitron 2000 is NIOSH
approved to supply a continuous flow of
cool air to Bullard 88, CC20, MB30 or
GR5 0 Se rie s air line re s p i ra t o rs. Al l
Bullard parts must be present and properly assembled to constitute a NIOSHa p p roved re s p i ra t o r. NOTE: Frigitro n
2000 can be used with a low pressure
air source such as an ambient air pump.
CAUTION: BEFORE USING THIS PRODUCT,
READ AND FOLLOW ALL DIRECTIONS AND
WARNINGS, INCLUDING THOSE IN THE
RESPIRATOR INSTRUCTION MANUAL.
DANGER
: Connecting the respirator to
a line supplying Nitrogen or other harmful
gases could cause death or serious injury.

Air Quality
The re q u i rements for Grade D bre a t hable air include:
WARNING
: The respirator's air
source must supply clean, breathable air,
Grade D or better, at all times. The respirator does NOT purify air or filter out contaminants.
– Oxygen ..............................................19.5-23.5%
– H yd roc ar bon s
(con d ensed )
in mg/m3 of gas.....................5 mg/m3 max.
– Carbon monoxide..................10 ppm max.
– Carbon dioxide ................1,000 ppm max.
– Odor .............................. No detectable odor
– No toxic contaminants at levels that
make air unsafe to breathe.
Respirable air must be supplied to the point of-a ttac hm en t of t he MSHA/ NIOSH
APPROVED BULLARD air supply hose.
The point-of-attachment is where the air
supply hose connects to the fitting that
contains a pressure gauge used to monitor the pressure of the air provided to
you.
Locate the source of supplied air in a
clean environment far enough from your
work site to ensure the air remains contaminant-free. Always use an inlet filter
on your air source and any monitors and
alarms as necessary to assure clean,
breathable air at all times.
Supplied breathing air MUST meet or
exceed the re q u i rements for Type 1
g a s e o u s ai r desc ribe d in th e C omp ressed Gas Association C o m m o d i t y
Specification G-7.1 ( G rade D or higher
quality) as specified by Federal Law 30
CFR, Part II, Subpart J, 11.121(b).
Refer to C.G.A. Co mmodity Specification G-7.1 for complete details, or contact the Compressed Gas Association
(1235 Jefferson Davis Highway, Arlington,
VA 22202).
Air Pressure
Continually monitor the air pressure at
the point-of-attachment while operating
the re s p i ra t o r. A reliable air pre s s u re
gauge must be present to monitor the
pressure.
DANGER : Failure to supply the minimum required pressure at the point-o f attachment for your hose length will
reduce airflow and may expose you to life
threatening conditions, diseases or death.
The BREATHING AIR PRESSURE TABLE
b e l ow defines the air pre s s u re ra n g e s
n e c e s s a ry to provide the 88, CC20,
MB30 or GR50 Series respirator with a
volume of air that falls within the required
range of 6-15 cubic feet per minute (cfm)
or 170-425 liters per minute (lpm). (See 30
CFR, Part II, Subpart J, 11.124.7).
Be sure you understand the information
in th e BRE AT HIN G A IR PRES SU RE
TABLE before using the respirator. To use
the table, follow the steps identified
below:
1. Following your air source in Column 1,
select your climate control dev i c e
from Column 2.
2. Determine the proper MSHA/ NIOSH
approved Bullard air supply hose(s)
(Colum n 3) to use with your C ool
Tube.
3. Determine that your air supply hose
d oe s not exc eed th e max i m u m
approved hose length (Column 4) or
number of hose sections (Column 5).
4. Set the air pre s s u re at the point-ofattachment within the required pressure range (Column 6) for your air supply hose length.
Breathing Air Pressure Table
This table defines the air pressure ranges necessary to provide the respirator with a volume of Grade D breathable air that
falls within the U.S. Government required range of 6-15 cfm (or 170-425 lpm). (See CFR Title 30, Part II, Subpart J, 11.124.7).

Air Supply Hose
To maintain your Bullard re s p i ra t o r ’s
MS HA /NI OSH a pproval, use o nl y
approved Bullard V20 Series hose(s) in
length s of 50-300 f eet between the
F r i g i t ron's quick-disconnect fitting and
the point-of-attachment to the hose.
MSHA/NIOSH approved
V20
Bullard quick-disconnect fittings MUST
be used to connect V20 hose lengths
together.
Use of any other air supply hose voids
the MSHA/NIOSH approval on the entire
respirator assembly and could reduce the
airflow to the respirator, possibly resulting in serious injury or death to the respirator wearer.

WARNING
: Before connecting the
Frigitron 2000 to the respirator, be sure
the breathing air at least meets the minimum Grade D requirements. (See Air
Quality section on front page.)
Preparation and Use of the Frigitron 2000
1. In an uncontaminated atmosphere ,
screw the end of the breathing tube to
the fitting on the climate control device.
Tighten hose connectors firmly
ual. If you do not have instructions,
contact Bullard Customer Service at
the address or phone numbers given
below.
2. Lace the belt supplied with the Cool
Tube through the belt bracket.
6. To obtain cooler air, turn either or both
of the air temperature control knobs
clockwise (Figure 1).
3. With the approved Bullard V20 air supply hose connected to the air source
and with air flowing into the hose, connect the quick-disconnect coupler on
the air supply hose to the quick-disconnect nipple on the Frigitron 2000.
4. Adjust the air pressure at the point-ofattachment to within the approve d
pressure range (Figure 2). See the Air
Pressure section at the top of page.
5. Put the hood on by following the directions in your respirator instruction man
E.D. Bullard Company
area wearing the respirator. With the
air still flowing into the hood, remove
the hood and then disconnect the air
supply hose using the quick-disconnect coupler attached to the Frigitron
2000.
M aximum cooling is attained when
either or both knobs are fully open and
when there is maximum airflow out of
the Frigitron exhaust ports.
To obtain air that is closer to ambient
t e m p e ra t u re, turn either or both air
t e m p e ra t u re control knob counterclo ck wise. If bot h knobs are fu lly
closed, your respirator will receive air
at ambient temperature.
