10.3.2.11 Nozzles. Use the industry standard nozzle. It
comes in three pressure ranges: 2,400 psig (16 500 kPa),
3,000 psig (21 000 kPa), and 3,600 psig (25 000 kPa). These
nozzles are designed so that a fill system cannot connect to a
vehicle tank with a lower pressure rating, yet it can connect
to vehicle tanks with higher ratings.
down automatically, releasing about 0.06 gallons (0.2 L) of
oil to the base and subsequently the ground. Discharges from
other components, such as intercoolers, add to the
required at each corner of the base. Develop a means of

alternative to a collection system.
b) Provide gas recovery system as part of the
compressor package to recover gas into an ASME recapture tank
when off-loading the compressor.
c) At the dispenser, provide a vent 8 feet (2.4 m)
to 10 feet (3 m) above ground level to discharge vent gas from
dispenser hoses. Oversize the conduit from the dispenser to
the cascade for a vent line to a future gas recovery system.
d) Locate units with care because of noise.

crankcase heaters and/or circulating block heaters may be
suitable in moderately cold climates.
