FRG Mounting Bands
• Two mounting bands are required for proper FRG
installation (see service parts listing in this section).
• Durable, corrosion resistant, galvanized steel construction.
• Engineered and tested to resist the adverse effects of
vibration.
• Mounting band feet are designed to continuously ensure
maximum torque pressure.
• Dimensional information for mounting bands can be found
in the accessories section.
Applications
• Horizontal installation
• Medium and heavy dust
environments
•
Style A
— From 82 to 795 cfm airflow
throughput per air cleaner in body
diameters ranging from 5" to 16"
(127 – 406mm)
•
Style B
— From 270 to 1390 cfm
airflow throughput per air cleaner in
body diameters ranging from 10" to
18" (254 – 457mm)
Ideal for
• Construction equipment
• Agricultural machinery
• Mining equipment
• Off-highway vehicles
Air Cleaner Features
• Two-stage filter system: the first
stage removes up to 85% of
incoming dust
– The first stage in the Style A uses
the angled vanes on the primary
filter
– The first stage in the Style B has a
tangential air inlet
• Inlet on side, outlet on end (G flow)
• Already tapped to accept filter
service indicator
• Vacuator
™
Valve automatically
releases the pre-cleaned dust
• Durable, long-lasting finish
– Style A housing is metal and
coated with a black, corrosion- and
chemical-resistant polymer paint
(service cover is accessed with
clamp and bolt)
– Style B is comprised of two
materials: injection molded, high
strength polymer service cover
and a metal body (the service
cover is accessed by latches)
• Mounting the unit directly to the
engine is not recommended;
excessive engine vibration can
cause premature air cleaner
structural failure
Filter Features
The RadialSeal
™
filter inside
the air cleaner is also quite
different from Axial filters. Its
one-piece, molded urethane endcaps
encase the filter media and liners, thereby
reducing the number of components and
increasing sealing reliability.
The inside surface of the filter’s open
end is the sealing surface, which
eliminates the glued-on gasket found
on the metal end cap of Axial filters. For
added engine protection during filter
service, consider a model with a safety
filter.
Durable, Vibration Resistant
Variety of Sizes in Two Separate Housing Styles
Injection-molded endcap, made of
specially-engineered resins for high
strength and durability, serves as
the service cover. Filter change out
is easier than ever — just unsnap
the latches to access the filter.
While it looks like an
axial seal air cleaner on
the outside, this new style
housing is equipped with a RadialSeal
™
style primary filter and an optional safety
filter. Easy to service; one wing-bolt clamp
to undo to access filter(s).
FRG Style A
The FRG Style A series replaces Donaldson’s
obsolete FHG series in size and airflow capacity.
FRG Style B
The FRG Style B series replaces Donaldson’s
obsolete FTG series in size and airflow capacity.
Accessories
Donaldson intake accessories for your
FRG Air Cleaner can help overcome or
prevent various problems. For instance:
• If the installed air cleaner will be
exposed to rain, snow or debris,
an
inlet cap
can prevent moisture
ingestion.
• A
filter service indicator
measures the
airflow restriction across the filter
and indicates when to replace the
filter (see Accessories section of this
catalog).
•
Mounting bands
for FRGs must be
ordered separately.
