3. ection 1 System Description Function and Theory The High Vacuum Sampler is an air sampling device that uses a compressor to draw air from a sampling source and convey that sample into sealable sample bags When an external 12 VDC power source connects to the unit the compressor is capable of producing a vacuum of up to 27 in Hg Typical applications include soil vapor points or Soil Vapor Extraction SVE systems Figure 1 1 is an example of the High Vacuum Sampler Each High Vacuum Sampler comes with a standard DC power cord Figure 1 2 to allow the unit to operate from a 12VDC battery or cigarette lighter An optional 110VAC power cord with adapter Figure 1 2 is also available 1 liter and 3 liter sample bags Figures 1 3 and 1 4 are available from Geotech which can be used to easily collect air samples See Section 8 for part numbers to these accessories geotech a HIGH VACUUM a SAMPLER g Vacuum In from air source Figure 1 1 Standard DC Power Cord d Battery Adapt and Battery Adapter Optional AC Power Cord and Adapter Figure 1 2 Figure 1 3 Example of ALTEF 1 Liter Bag Figure 1 4 Example of Tedlar 1 and 3 Liter Bags Section 2 System Installation Verify the 12VDC system to be used is rated and fuse protected for operation at 15 amps continuous operation Failure to verify system rating could result in damage to equipment Over heated wiring and other materials or components in contact o
