Call our customer service 877-873-6994
In the 1990s this was the smallest constant flow oxygen concentrator available, with current
models now days this is considerd about the normal stationary oxygen concentrator.
It is still small and light weight enough to move or transport. Works on Pressure/Vacume system. Supports high performance and long life with small siever beds. The Vacume assisted purge creates a predictable / reliable system. Electriclly shifted soleniod valve. Increased shift efficiency and valve life. Oxysiv-7 sieve beds. Ideally suited for the 303's single valve, low pressure / vacume system. Longer and more productive life.
At American Medical Sales and Repairs Inc. We repair, sell and rent the Devilbiss 303DZ, our staff has been working on this model since the 1990s when it was most popular.

How does an Oxygen Concentrator work?
An Oxygen Concentrator uses the ambient air, which is normally 80% nitrogen and only
20% Oxygen. The oxygen concentrator separates the two components by using zeolite
granules to selectively absorb nitrogen from the compressed air. The compressor raises
the air pressure to about 20-lbs per square inch (P.S.I). The compressed air is
introduced into one of the canisters containing zeolite granules where nitrogen is
selectively absorbed leaving the residual oxygen available for patient use. After about
20 seconds the supply of compressed air is automatically diverted to the second
canister where the process is repeated enabling the output of oxygen continue
uninterrupted. While the pressure in the second canister is at 20 P.S.I. the pressure in
the first canister is reduced to zero. This allows nitrogen to be released from the zeolite
and returned into the atmosphere. The zeolite is then regenerated and ready for the
next cycle. By alternating the pressure in the two canisters so that first one and then the
other is at 20 P.S.I., a constant supply of oxygen is produced while the zeolite is
continually being regenerated. Individual units have an output of up to five litres per
minute with an oxygen concentration of up to 95%.
What is Zeolite?
The word 'zeolite' is Greek in origin and means 'boiling stones' as natural zeolites visibly
lose water when heated. Zeolite is an inorganic porous material having a highly regular structure of pores and chambers that allows some molecules to pass through, and
causes others to be either excluded, or broken down. It is in many ways, the inorganic equivalent of organic enzymes, many of which also have specific sized chambers that
trap chemicals within our bodies, holding them where they either break down, or react
with specific chemicals. Zeolite has many uses.

Who uses O2 concentrators? COPD Patients.
An estimated 11 million Americans suffer from chronic obstructive
pulmonary disease (COPD), an illness with disabling symptoms,
high cost of care, and substantial mortality. COPD is an obstructive
airway disease that is characterized by a reduction noted on the
individual's pulmonary function study. The term COPD is often
applied to a family of diseases, including emphysema, chronic
bronchitis, and alpha 1-antitrypsin disease. Currently, therapeutic
interventions can slow the progression of these diseases, but they
cannot stop or reverse it.
