Air Compressor
The Echo Liquid Handler requires a compressed air source that provides clean, filtered, oil-free, dry air at 552 kPa (80 PSI) minimum
and 1034 kPa (150 PSI) maximum. The Junair OF302-4B oil-less compressor can be purchased from Labcyte (Part #001-12164).
Note: The Junair OF302-4B compressor is only 115VAC/60Hz and is only suitable for North America.
The user must also provide a fitting between the compressed air supply and the Echo Liquid Handler. Labcyte provides the
compressed air line and fitting with the Echo Liquid Handler, but the customer must provide a source compatible with 170 in
ID/.250 in OD tubing.
