Its Finest

Carrier’s FA4B, FB4B, and FC4C 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 fan 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 FA4B is a residential new construction (RNC) model available with or without factory-installed disconnects. It has a pre-painted galvanized insulated steel casing, 2-speed motor in 018 through 036 sizes and 3-speed motor in 042 through 060 sizes. The FA4B is equipped with an AccuRater® metering device.

The FB4B is the standard of Carrier fan coils. It comes in a prepainted galvanized steel casing with 1-in. 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 FC4C is a deluxe design fan coil incorporating all the features

A02305 found in the FB4B. In addition, it has a hard shut-off thermostatic expansion

valve (TXV) metering device with internal check valves for reverse-flow bypass capability. The FC4C is available in sizes 024 through 070.
