GENERAL SAFETY GUIDELINES

Only persons who have read and understood this entire manual should be allowed to
install and operate the Max 30 Oxygen Concentrator (hereafter known as the device).

The WARNINGS below indicate a potentially hazardous situation. If conditions are not

avoided a situation could occur that results in serious injury or death.

• Oxygen is not a flammable gas, but it accelerates the combustion of materials. Do not use in
explosive atmosphere. To avoid risk of fire and explosion the concentrator should be kept
away from Flames, Heat sources, Incandescent sources, Smoking Materials, Matches, Oil,
Grease, Solvents, Aerosols, etc. Do not allow oxygen to accumulate on upholstery or other
fabric such as bedding or personal clothing. If concentrator is operating while not connected
to patient, position cannula so that the gas flow is diluted in the ambient air.

• Improper patient connection to and use of the cannula may result in injury including
strangulation. Avoid situations that might cause the cannula or hose to become entangled
about the patient’s neck.

• Use of other accessories not described in this User's Guide are not recommended. Patient
benefit may be diminished.

• No modification to the equipment is allowed. To do so may affect patient benefit.

• Contraindications; those who continue to smoke (because of the increased fire risk and the

probability that the poorer prognosis by smoking will offset the treatment benefit).

• Device must have power to operate. In the event of power loss and for continued operation a
backup source is recommended.

• DO NOT disassemble due to danger of electrical shock. Refer servicing to qualified service
personnel.

• To avoid the risk of electric shock, this equipment must only be connected to a supply
mains with protective earth. If not available, contact a qualified electrician. Do not defeat
this safety feature.

The CAUTIONS below indicate a potentially hazardous situation. If conditions are not

avoided a situation could occur that results in property damage or minor injury or
both.

• Use the power cord provided, and check that the electrical characteristics of the power
socket used match those indicated on the manufacturer’s plate on the rear panel of the
device.

• We recommend against the use of extension cords and adapters, as they are potential
sources of sparks and fire.

• The device has an audible alarm to warn the user of problems. In order that the alarm may
be heard, the maximum distance that the user can move away from it must be determined to
suit the surrounding noise level.

• The device must only be used for oxygen therapy and only on a medical prescription. The
indicated daily duration and flow must be followed, otherwise it may present a risk to the
health of the patient.

• Do not position device so that it is difficult to access the mains power cord, so that it
accessible for disconnect.

• Do not use in a specifically magnetic environment (MRI, X-ray, etc.). May cause device malfunction.

• Note: Medical Device Regulations require users and service providers to report to the manufacturer

any incident that could, if repeated, result in injury to any person.

Product Information

Features and Applications

The NMP Model MAX 30 extracts oxygen from the atmosphere using Pressure Swing
Adsorption (PSA) technology. It concentrates oxygen up to 93% (± 3 %) purity which
can be applied in various ways.

Features

Easy to use

Just connect to an electrical outlet, turn the Master Switch ON/OFF power switch to the ON
position and press the START button on the front display panel and set the desired flow rate.

Dependable

Its internal air compressors, filtration system, molecular sieve, storage tanks and flow control
system are designed for 24/7 operation.

Durable

With oxygen-clean brass tubing and valves, the MAX 30 can operate even in environments as
described under the specifications page.

Safe

A built-in oxygen pressure regulator maintains oxygen outlet pressure at 50 psi (3.4 bar). Each
of the compressors on the MAX 30 has 0.38 hp and have a built-in safety relief valve to prevent
excessive pressures in each compressor.

Pressure Swing Adsorption (PSA) Technology

An NMP Oxygen Concentrator is an on-site oxygen generating machine capable of producing oxygen on
demand in accordance with your requirements. In effect, it separates the oxygen (21%) from the air it is
provided and returns the nitrogen (78%) to the atmosphere through a waste gas muffler. The separation
process employs a technology called Pressure Swing Adsorption (PSA). At the heart of this technology
is a material called Molecular Sieve (synthetic zeolite). This sieve is an inert, ceramic-like material that is
designed to adsorb nitrogen more readily than oxygen. Each of the two beds that make up each of the
enricher contains this sieve. The process is described below.

Stage 1 Compressed air is fed into the first molecular sieve bed. Nitrogen is trapped, while oxygen is allowed

to flow through.

Stage 2 When the sieve in the first bed becomes full of nitrogen, the airflow is then directed into the second

bed.

Stage 3 As the second bed separates the oxygen from the nitrogen, the first bed vents its nitrogen into the

atmosphere.

Stage 4 Compressed air is once again fed into the first bed and the process is repeated continuously. A

constant flow of oxygen is produced

This air separation process is reliable and virtually maintenance-free.
The molecular sieve will last indefinitely, as long as it does not become contaminated with water or oil
vapors. This is why regular filter element replacement is crucial to trouble-free operation. The filter
elements are inexpensive and require semi-annual maintenance.
