Instructions for use and maintenance SATA air star C
4. Manner of action of the air-cleaning unit with the 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 precleaning of the sup-
plied compressed air. For this purpose it is necessary to interpose the
SATA filter 444 compressed-air filter with condensate drain. This device
filters nearly all water and dust particles out of the compressed air. The
fine filter cartridge must be exchanged (change every 6 months at
the latest; see Operating Instructions SATA filter 400) when the pressure
difference between the manometer mounted on the SATA filter 444 (Art.
No. 92296) is larger than 1 bar.
An activated charcoal filter (D) is included for further
removal of oil vapors from the breathing air. The acti-
vated charcoal filter SATA filter 464 (Art. No. 92247)
and the combi fine filter activated charcoal unit SATA
filter 494 (Art. No. 92338) should regularly be maintai-
ned and tested for perfect function. The activated
charcoal filter cartridge should be changed every 3
months in order to avoid saturation.
The time indicator for a regular filter change is part of the scope
of delivery of each filter and each exchange filter cartridge!
- For standard version, air cleaning unit 55798
Once the activated charcoal cartridge is saturated, just remove protective
cage, unscrew transparent PVC bell and install new activated charcoal
cartridge (exchange every three months). Put on included label to the
protective cage of the absorber, thus ensuring that the exchange date is
observed. The control valve for the volumentric air flow rate is designed
in such a manner that, at a minimum operating pressure of 4 bar without
compressed-air unit, approx. 150 Nl/min cleaned air is supplied to the
half-mask respirator (pressure indication still within the green area). The
volumentric air flow rate can be increased to over 300Nl/min by opening
the control valve (position -H-).
- With the alternative version, industrial belt unit 58941
When the activated charcoal filter cartridge has become saturated, uns-
crew the filter tube on the SATA filter 464, unscrew the filter cartridge, and
insert a new filter cartridge in reversed sequence (change interval every
3 months). Unscrew the viewing window, remove the old indicator strip
and insert a new one. The control valve for the volumentric air flow rate
is designed in such a manner that, at a minimum operating pressure of 4
bar, approx 150 Nl/min cleaned air is supplied to the half mask respirator.
The volumentric air flow rate can be increased to over 300 Nl/min by
opening the control valve (position -G-).
