Air Handling Technology At
Its Finest
Carrier’s FA4A, FB4A, and FC4B
direct expansion multipoise fan coils
are designed to cover a wide range
of air handling requirements. They
are compact and ready to fit where
needed — in the basement, crawlspace, attic, utility room, or closet.
All units come with solid-state
power board controls, 1-in. insulation
with an R value of 4.2, super-quiet
multispeed motors, and fully wettable
coils. Units can accommodate factoryor field-installed heaters from 3 to
30 kw.
The FA4A is the residential new
construction (RNC) model in the
line-up. It is available with or
without factory installed disconnects. It has an embossed
galvanized steel casing, 2-speed
motor in 018 through 036 sizes
and 3-speed motor in 042 through
060 sizes. The FA4A is equipped
with an AccuRater
The FB4A is the standard of
Carrier fan coils. It comes in a
prepainted galvanized steel casing
with foil-faced insulation and has a
3-speed motor in the full range of sizes
018 through 070. All units are
equipped with an AccuRater metering
device and are also shipped with a
cleanable, permanent framed filter.
The FC4B is the deluxe design in
the fan coil group. It incorporates all
the features found in the FB4A. In
addition, it has a hard shut-off
thermostatic expansion valve (TXV)
metering device with internal check
valves for reverse-flow bypass
capability. The FC4B is available in
sizes 024 through 070.
