Vent the GC externally to the building via an ambient-pressure vent system, within 460 cm (15 ft) of the GC split vent or vent to a fume hood. Note that an exhaust vent system is not part of the building environmental control system, which recirculates air.

Exhaust venting must comply with all local environmental and safety codes. Contact your Environmental Health & Safety (EHS) specialist.

For GCs with the exhaust deflector option installed, the exhaust is about 65 ft3/min (1.840 m3/min). Without the deflector, the exhaust rate is about 99 ft3/min (2.8 m3/min). The deflector outlet diameter is 10 cm (4 in).
