1. General notice The STEPHAN – S T A X E L - unit serves for the production of oxygen and compressed air as well as for the production of vacuum and is primarily designed for the operation of appliances for pediatrics and anaesthesia.
STAXEL O2 and AIR Service Manual 3. Construction and description of performance 3.1 Production of oxygen The production of oxygen is based upon the adsorption effect of molecular sieves. For this purpose, air which has been compressed by compressors is blown through two containers, which are filled with molecular sieves.
The entire module is mounted onto a sturdy undercarriage with an appropriate holding rail, so that all STEPHAN respirators as well as reanimators (pediatrics respirator F 150 and HF 300 SIMV) can be used. The respirators can easily be detached from the unit and attached to a wall rail system or to the incubator.
Installation and startup Environmental conditions The STEPHAN S T A X E L is intended for installation in dry rooms without risk of splash water or water drops. Humid or wet environment can seriously impair the reliability of the unit.
STAXEL O2 and AIR Service Manual 4.2 Startup First the STAXEL is connected to the mains supply (socket). The STAXEL has two mains switches, one mains switch for the production of O2 and AIR and a second one for the generation of vacuum. By means of the mains switch ′O2 and AIR′...

The connections are quick- coupling and are are interlocked automatically after plugging in.
STAXEL O2 and AIR Service Manual Technical description 7.1 Description of system Ambient air is taken in via a microfilter, led through a silencer inlet and finally compressed in the compressors 1 + 2. The compressed air is then conducted over a condenser and cooled, before it is collected in a pressure compensation reservoir.
STAXEL O2 and AIR Service Manual Switching attitude of the valve unit Switching position A: Medicinal compressed air of 1,7 bar from the pressure compensation reservoir is available at the valve unit. In switching position A the valves 1 + 4 are open. Through valve 1 flows compressed air through the adsorber container A.

STAXEL O2 and AIR Service Manual The changeover between adsorber A and B takes place cyclic and continuously. All the switching times are a fixed program in the control electronics of the STAXEL and can not be altered. Switching cycles can be checked by means of the LEDs on the control board.

Service Manual Maintenance Maintenance The Stephan STAXEL requires only little maintenance. For hygienic reasons the unit should be cleaned periodically by wiping it, using customary household cleansing agents or disinfectants ( e.g Sagrotan, diluted ). The microfilter and the filter mat must be exchanged every 10 days or after each 240 hours run.
STAXEL O2 and AIR Service Manual 13. Service To warrant faultless performance, the units must be checked after each approximate 1000 hours run, at least, however, once a year, by an authorized specialist firm. Eventually occurring disorders or failures must only be eliminated by the service department. After 10.000 hours run, a general overhaul has to be carried out by the service department.
STAXEL O2 and AIR Service Manual 13.4 Adjustment of the adsorber containers To guarantee a faultless performance of the STAXEL, a check and in case a renewed calibration of the pressure controllers on the O2-reservoir should be carried out with each servicing. In addition, the adsorber containers must be checked.
