Model ACS3920

CO₂ Free Dry Air Compressor System

A Fully Enclosed Compressed Air Supply, Air Dryer & Sound Muffling Enclosure

The ACS3920 Air Compressor System with integral CO₂ Adsorber/Air Dryer provides a clean, dry, continuous duty gas supply for the Thunder Scientific Low Humidity Generators. The ACS3920 Air Compressor System consists of a vibration isolated 3/4 HP oil-less compressor, membrane air dryer, CO₂ Adsorber/Air Dryer, and adjustment regulators, all incorporated into a sound muffling enclosure. The ACS3920 is ideal for laboratory use due to its small size, 100 psiG pressure output at 10 L/min, with an ambient pressure -70 °C FP, 100% duty cycle capability, and a low sound level of less than 70 decibels.

NOTE: When using the ACS3920 with a Model 3920 or Model 3900 Low Humidity Generator the working range of the generator will be limited by the lower pressure and overall dryness outputted by the ACS3920. You will only be able to generate down to around a -70 °C frost point when using the ACS3920. It is also important to adjust the internal Model 3920 or Model 3900 regulator to 80 to 90 psiG to assure proper pressure control.

PRINCIPLE OF OPERATION

To provide the Model 3920 Low Humidity Generator with a clean, dry air supply when you can't provide a nitrogen gas source and to give the laboratory a noise level that's acceptable for the lab technicians to carry on with their calibrations. Also has the ability to start automatically when using the remote-control cable.

ACS3920 Physical Dimensions

APPLICATIONS

The ACS3920 Oil-Less Compressed Air System is designed to be used as the air supply for the 3920 low humidity generator. The ACS3920 consists of a vibration isolated oil-less piston compressor, membrane style air dryer, and output regulator, all incorporated into a sound muffling enclosure. The ACS3920 is ideal for laboratory use because of its high pressure capability, 100% duty cycle capability, low sound level of less than 70 decibels, and long service life.
