Medical Oxygen Concentrator
This unit is used but fully functional to concentrate oxygen for medical use. We have the tubing and masks to go with it (disposable items) to show a sick patient in a movie scene or giving someone exhausted first aid.
It can be a prop or it can actually be used if anyone on set is under oxygenated, tired or weak from heat or other ailments.
We also have smaller compact units for home use for oxygen therapy. They are modern digital with touch screens while this unit is less complex and would be more common in a hospital or convalescent facility.
These units replace oxygen tanks which have to be constantly refilled making a long dependable supply of O2 possible.
