Air Handling Technology At 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 factory- or 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
