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 is 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.
