New, Used, Rebuilt, and Rentals available
Call our customer Service 1-877-901-1464

In the 1990s this was the smallest constant flow oxygen concentrator available, with current models now days this is considered about the normal stationary oxygen concentrator.

It is still small and light weight enough to move or transport. Works on Pressure/Vacuum system. Supports high performance and long life with small siever beds. The Vacuum assisted purge creates a predictable / reliable system. Electrically shifted solenoid valve. Increased shift efficiency and valve life. Oxysiv-7 sieve beds. Ideally suited for the 303's single valve, low pressure / vacuum 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?


Oxygen Concentrator Zeolite 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.
