Fan Powered Terminal

45J – Series - Nominal 90 to 3900 Cfm
45M – Parallel - Nominal 90 to 3700 Cfm
Carrier 45J Fan Powered Terminal

The 45J and 45M fan-powered units are designed to maintain optimum temperatures in the conditioned zone through the accurate mixing of plenum return air and cold primary air. The 45J,M terminals offer excellent performance characteristics and affordability in a compact unit with optimum physical dimensions.
