Oxygen filling apparatus
First Claim
1. An oxygen filling apparatus for filling oxygen cylinders, comprising:
- an oxygen generator unit having a molecular sieve and an air compressor adapted to supply air to said molecular sieve;
a plurality of pressure sensors;
an oxygen purity sensor;
an oxygen discharge valve adapted to supply oxygen produced by said oxygen generator unit to one or more oxygen cylinders; and
a control unit having a touch sensitive screen interface configured to selectively display current and historical operational parameters.
