FAQs

Filter cartridges need to be replaced according to an infrequent but essential maintenance schedule. A recommended spare parts list is supplied with every system. Annual costs vary, depending on system type, size and filter requirements. Please contact us for more details.

Our typical system is composed of a generator of nitrogen or oxygen, and a receiver tank. The complete operating system also requires a feed air compressor, a dryer and air-receiving tank. While On Site Gas does not make air compressors, dryers or tanks, we offer them as part of the system package.

The receiver tank allows the gas to be delivered to your application at a steady flow rate and a consistent pressure.

An air dryer assures that air is supplied at the proper dew point for the ultimate generator performance.

Our generators require less then .5 amps at 110 or 220 Volts, 50 or 60 Hz, 1 Phase.
