1) Capacity is referenced to psig inlet conditions as noted, 68°F inlet temperature @ 80% of the compressor’s maximum working pressure. Tolerance +5/-4%

2) One GGE (Gasoline gallon equivalent) of natural gas is 126.67 cubic feet (3.587 m3) at standard conditions.

3) CN303-5 compressors meets NFPA 1052, section 10.1.2., 5 SCFM threshold for Residential Fueling Facility.

4) Specifications are subject to change.
