Compressor
Under normal conditions, the following information about the compressor
will provide satisfactory guidelines for selecting the right compressor
for your needs. Unusual operating conditions may require a larger unit
than indicated. If you are not certain, select a larger unit to ensure
adequate initial capacity and provide for future needs.
Power Source
It is very important to determine the correct electrical service
available to your location. Make certain the compressor you have selected
will have the correct power available for proper operation. Incorrect
voltage or phase will delay installation. Contact a professional
electrician to determine the electrical services in your facility.
Gasoline or diesel engines are available if a mobile unit is desired over
a stationary design. Chart A illustrates proper
electrical service required for a high pressure breathing air compressor.
Compressor Air Intake Requirements
It s important to provide fresh, uncontaminated air to the compressor's
intake. Gross containment of intake air will adversely affect the
efficiency of the purifier, for instance:
If the compressor is operated near running vehicles or close to a gas
heater, the CO and CO2 levels in the ambient air may be affected and
will have an adverse impact o the air quality output by your system. If
the compressor is located in a room where chemicals are stored, fumes or
particles can be drawn into the system and affect air quality. Your
compressor should never be located where volatile gases can enter the
compressor.

| Full load currents, wire
size and switch sizes are based on 1984 NEC. Fuse sizes and
breakers' amp ratings are estimatated selections suitable for most
installations; consult a professional electrician to determine
appropriate electrical service required. |
