3. Manner of operation of the air-cleaning unit with activated-carbon adsorber and waistbelt unit without
activated
carbon adsorber
The service life of the activated-carbon cartridge and the quality of the respiratory air depends primarily upon the level of pre-
cleaning of the supplied compressed air. For this purpose it is necessary to interpose the SATA 0/444 compressed-air filter with an
automatic condensate drain. This device filters nearly all water and dust particles out of the compressed air. The fine filter cartridge
must be exchanged (see Operating Instructions SATA Air Filter) when the pressure difference between the manometer mounted
on the 0/444 is larger than 1 bar.
Saturation of the activated-carbon filter (E) is readily discernible by the blue colouration of the indicator strip.
The activated charcoal filter cartridge should be changed every 3 months in order to avoid saturation, or after testing the air in
accordance with the stipulations of the standard AS/NZS 1715 for compressed air.
The time indicator for a regular filter change is part of the scope of delivery of each filter and each exchange filter cartridge!
- For the standard version - Air Cleaning Unit 54015
After saturation of the activated charcoal filter cartridge, which can easily be recognized by the blue colouring of the indicator
strip, you only have to remove the protective cage, to unscrew the transparent plastic bell and to insert a new activated charcoal
filter cartridge (change interval every 3 months). The control valve for the volumetric air flow rate is designed in such a
manner that, at a minimum operating pressure of 4 bar without compressed-air unit, approx. 170 Nl/min (240 Nl/min) cleaned
air is supplied to the respirator mask (pressure indication still within the green area). The volumetric air flow rate can be increased
to over 300 Nl/min by opening the control valve (position -H-). If the air volume stream is further increased, ear protection must
be worn.
- For the alternative version, waistbelt unit 58941 (82719)
The control valve for the volumetric air flow rate is designed in such a manner that, at a minimum operating pressure of 4 bar,
approx 170 Nl/min (240 Nl/min) cleaned air is supplied to the half mask respirator. The volumetric air flow rate can be increased
to over 300 Nl/min by opening the control valve (position -H-).
4. Maintenance, Care and Storage
- After the respirator has been used, ensure that it is thoroughly cleaned and disinfected, and then subjected to a performance
and leakage test (briefly submerge the adsorber unit in clear water while it is under pressure and ready for operation).
- Check the filtering cartridge (E) for oil saturation.
- Check the control valve (H) for smooth action.
- Check the volumetric air flow rate indicator (P) for damage.
- Check the performance of the compressed air filter (B) and the pressure gauge reading. If necessary, clean the sintered bronze
filter, e.g. with solvent, and replace the fine filter cartridge (see Operating Instructions SATA Air Filter).
- Clean at regular intervals - daily/weekly intervals when it is used every day, and when not air-tight packed. For this purpose, the
hood lining can be removed. The hood lining must be replaced when it has become soiled (See Spares List for Order No.). If
the same hood is worn by several people, then it must be disinfected each time the wearer changes. In such instances it would
be more appropriate to ensure that each person has his or her own respirator hood. This hood must be cleaned depending on
the duration of use.
We recommend „Incidur" disinfectant made by Henkel. The respirator hood must be cleaned at the latest in half-
yearly intervals, and this must be combined with a performance and leakage test; the activated-carbon
cartridge (change interval every 3 months or after testing in accordance with the stipulations of the standard
AS/NZS 1715) must be exchanged (replacement cartridge and new unit have a shelf life of 5 years when
stored in an air-tight state). The mask should be stored in a clean dry place while it is not being used, but not in the spray
booth.
5. Remarks concerning application
- CAUTION:
1. On account of their specific design, compressed-air hose respirators, EN 270, AS/NZS 1715, with respirator hood (closed visor)
for respiratory protection must not be used in a poisonous ambient atmosphere in which oxygen deficiency prevails or in which the
maximum workplace concentration value (MAK and TRK) is exceeded 100-fold. (EN 1835 x 5-fold)
2. The respirator hoods may only be used with correctly clipped foil.
- Upon fixing the foil, make sure it fits tight with the inner sealing edge of the visor. (vision 2000)
- A performance and leakage test should be completed with the entire set prior to each use.
- Not everyone can wear mask respirators. All persons who are to wear mask respirators must be medically examined
in line with the requisite industrial medicine regulations for wearers of respirators at work and in life-saving services
("Berufsgenossenschaftlicher Grundsätze für arbeitsmedizinische Vorsorgeuntersuchungen G 26: Träger von Atemschutzgeräten
für Arbeit und Rettung"; Published by: A.W. Gentner-Verlag, Stuttgart, Germany), and the Guidance Note on Respirators BGR
190.
- The air supply for the respirator is independent of individual requirements. The actual respiratory air requirements of the respi-
rator hood wearer can be individually adjusted with the control valve (H).
- Any modification of the respirator system or mask, belt unit, air hoses etc., combination with other products or with spare parts
of other products by SATA or other manufacturers affects the safe operation of the respirator, may lead to serious harm to
the user health, permanent harm or loss of life may follow and is in no way permissible. Serious danger to health, permanent
harm or even loss of life may follow if insufficient compresed air is used for breathing (Respect applicable rules of the resp.
country).
Subsequently the certificate of model will become void and also the CE sign.
- The respirator hood must only be operated with the approved compressed-air supply hose (max. length 50 m; with waistbelt
unit 30668 max. 6 m) with safety rapid-action coupler (e.g. SATA Order No. 49080, 6 m).
- WARNING: To disconnect the safety rapid-action coupler simply depress the coupling nipple into the coupler and simulta-
neously push back the sliding sleeve.
