Direct Expansion

FB4A FC4B

Fan Coil

Sizes 018 thru 070

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 factory- or ﬁeld-installed heaters from 3 to 30 kw.

The FA4A is the residential new construction (RNC) model in the line-up. 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 FB4A 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 valve for reverse-ﬂow bypass capability. The FC4B is available in sizes 024 through 070.
