1. IMPORTANT INFORMATIONS

IMPORTANT

Before use, adjustment or maintenance, it is important to read this instruction manual very carefully.
This manual must be stored in a safe place for any future reference that may be necessary.
The AIRFED PROTECTION MASK KIT is a compressed air fed respirator which, when supplied with breathable quality com-
pressed air, passes it via a belt-mounted regulator and flexible tube into a visor. The regulator is fitted with a replacement
nuisance odour filter. These instruction must be read in full before operating the equipment.
Failure to follow these instructions completely may result in a decrease in protection or no protection at all.
Any misuse or handling other than those indicated in this Instruction Manual is not covered by guarantee. ANEST IWATA
disclaims all responsibility for any accident or damage caused by failure to observe the operational and safety procedures as
from this manual. In the interest of user friendliness, this manual contains information in a brief and concise form.
For any additional information you may require regarding equipment operations, or if any missing parts or any damage during
transportation is found, please contact your nearest ANEST IWATA Company (see last cover page).
2. DESCRIPTION
WHEN RECEIVING THE AIRFED MASK, MAKE SURE THAT IT HAS NOT BEEN DAMAGED DURING
TRANSPORT OR STORAGE.
EQUIPPED WITH:
Browguard and vizor - Cover for vizor - Waistbelt - Pre-set air regulator - Carbon filter - Gun hose fittings 1,25 m
This visor system conforms to provisional European Standard EN14594:2005. Specification for "Light Duty Compressed Air
Breathing Apparatus Incorporating Helmets or Hoods".
3. APPLICATION
The AIRFED system will provide protection against airborn dusts, mists, gases and vapours. This system offers respiratory protection to class
LDH-3 and hence offers a protection factor of up to 200. This means that it can be used in areas where the concentration of contaminant in
the workplace air is up to 200 times the Occupational Exposure Limit (O.E.L.)
- This system should not be used where the level of contaminant exceeds 200 x the O.E.L. or where the contami-
nant or its level is unknown.
- This system should not be used in oxygen deficient atmospheres.
- This system should not be used below 0°C.
4. OPERATE
4.1 AIR SUPPLY SPECIFICATION
The air supply must be of breathable quality as defined in EN132:1998. The air supply system should be
equipped with a pressure relief safety valve.
• Input pressure: 5.0 bar
• Min. air consumption: 140 l/min
• Max. air consumption: 300 l/min
4.2 AIR SUPPLY HOSE SPECIFICATION
The system should be used with a ø 5/16" supply hose with maximum working pressure of 15 bar and maximum
length of 10 m.

4.3 VIZOR AIR SUPPLY SPECIFICATION AND AIR FLOW INDICATOR
MINIMUM DESIGN FLOWRATE: 140 l/min.
An AIR FLOW INDICATOR is positioned in the visor on the left-hand edge of the wearer's field of vision. When
the flow of air drops below the minimum design flow rate quoted above, the float will just break the upper edge
of the opaque portion of the tube (refer to fig. 1). If a drop in air flow is indicated in this way, perform the checks
listed below under "Air flow indicator troubleshooting".
4.4 REGULATOR SPECIFICATION
This regulator has limited adjustment. Do not attempt to over-adjust it. This adjustment allows to the user to
maintain suffecient air flow to the visor when using auxiliary attachments and to adjust for comfort.
Every regulator has marked a serial number. The last two figures of the serial number correspond to the year's
manufacture.
BEFORE USE:
THE FOLLOWING SHOULD BE PERFORMED IN AN UNCONTAMINATED AREA.
• Check that the air supply pressure and flow available are in accordance with the AIR SUPPLY SPECIFICATION
(chap. 4.1)
• Inspect the equipment before use for any signs of damage or deterioration. Do not use the equipment if it
appears damaged.
• Fit the belt with the regulator attached around the operator's waist with the regulator on the side of the body
and the fitting
to take the air from the breathable air supply pointing forward. Lock the buckle and adjust the belt to a com-
fortable
tightness.
• Connect the male end of the main air supply hose to the main air supply. Connect the female end of the main
air supply
hose to the male inlet of the regulator. (See Figure 2)
• Examine the visor and replace the visor cover if contaminated, by pulling it off and pushing a new visor cover
over the two
metal studs.
• Connect the visor to the outlet of the regulator ensuring that it is locked in place.
• If spray gun is to be used, connect spray gun to the spray take-off.
• Check the air quality from the visor. If any odour is detectable then the carbon filter should be replaced. (See
maintenance
section for details on replacing the filter). If an odour is still detected then the visor should not be used. The
cause should
then be investigated since further prefiltering will probably be required.
• If an accessory such as spray gun or power tool is to be driven from the same compressed air supply tube,
ensure that the airflow indicators shows that sufficient flow is being delivered into the visor when the
accessory is consuming the maximum airflow requirement.
