Frigitron 2000 Cool Climate
Control Tube Instruction Sheet
INCLUDES: Frigitron 2000 and Belt
Breathing Tube
FUNCTION: The Frigitron 2000 is NIOSH approved to
supply a continuous flow of cool air as part of Bullard
supplied air respirator systems. Please consult the
NIOSH approval matrix in your respirator user manual to
verify that the Frigitron 2000 is NIOSH approved for your
specific configuration. All Bullard parts must be present
and properly assembled to constitute a NIOSH-approved
respirator.
NOTE:
Frigitron 2000 can be used with a low pressure air
source such as Bullard ambient air pump Models
ADP20, EDP30, and ICEPUMP11.

Air Quality, Air Pressure and Air Supply Hose Length Requirements
Air Quality
Air Pressure
Continually monitor the air pressure at the point-of-attachment while operating the
respirator. A reliable air pressure gauge must be present to monitor the pressure.
� 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.
� WARNING
Respirable air must be supplied to the point -of-attachment of the 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.
Failure to supply the minimum required pressure at the point-of-attachment for your
hose length will reduce airflow and may expose you to life threatening conditions,
diseases or death.
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.
The BREATHING AIR PRESSURE TABLE in your respirator user manual defines the air
pressure ranges necessary to provide the 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 the BREATHING AIR PRESSURE TABLE before using the respirator.
Supplied breathing air MUST meet or exceed the requirements for Type 1 gaseous air
described in the Compressed Gas Association Commodity Specification G-7.1 (Grade D or
higher quality) as specified by Federal Law 30 CFR, Part II, Subpart J, 11.121(b).
The requirements for Grade D breathable air include:
Oxygen.............................................................................................................. 19.5-23.5%
Hydrocarbons (condensed) 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.
Refer to C.G.A. Commodity Specification G-7.1 for complete details, or contact the
Compressed Gas Association (1235 Jefferson Davis Highway, Arlington, VA 22202).
Air Supply Hose
To maintain your Bullard respirator’s NIOSH approval, use only approved Bullard V20
Series hose(s) in lengths of 25-300 feet between the Frigitron’s quick-disconnect fitting
and the point-of-attachment to the hose.
Bullard quick-disconnect fittings MUST be used to connect V20 hose lengths together.
Use of any other air supply hose voids the 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.)

Control Tube Instruction Sheet
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.
2. Lace the belt supplied with the Cool Tube through the belt bracket.
4. Adjust the air pressure at the point-of-attachment to within the approved pressure range (Figure 2).
5. Put the hood on by following the directions in your respirator instruction manual. If you do not have instructions, contact Bullard Customer Service at the address or phone numbers given below.
6. To obtain cooler air, turn either or both of the air temperature control knobs clockwise (Figure 1).
Maximum cooling is attained when either or both knobs are fully open and when there is maximum airflow out of the Frigitron exhaust ports.

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.

To obtain air that is closer to ambient temperature, turn either or both air temperature control knob counterclockwise. If both knobs are fully closed, your respirator will receive air at ambient temperature.
7. When finished working, leave the work 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.
