Retail CNG Dispenser Manual
3.3.3 Filters
CNG may be filtered in one of two methods:
Particulate
filtration removes solid
particles from gases; ensuring only clean
gas is dispensed into a vehicle.
Coalescing
filtration removes solid
particles with the same efficiency as
particulate filtration, but also removes
water aerosols and droplets from gases;
ensuring only clean and dry gas is
dispensed into a vehicle. This is the
standard and recommended method of
filtration for all Kraus CNG dispensers.
Filter size and placement
Filter sizes and their placement depend on the configuration of the
dispenser. High-flow dispensers require large filters that may be
placed in one of the following locations:
In the
dispenser
pit if it is large enough to
house the filters, while providing enough
room to drain and change filter elements
Upstream of the dispenser pit, on the
dispenser supply lines between the
priority panel and the dispenser
See
Figure 1
below for high-flow filter placement options.
Standard-flow dispensers use smaller filters that can often be placed
in the lower cabinet of the dispenser unless otherwise indicated.
ATTENTION
If filters are not being supplied by Kraus Global Ltd., ensure that they are
properly rated for the dispenser’s filling system.
