Condenser Radiator Diffuser (Fan Shroud) Thermo King Part 77-2903 / 772903

The Condenser Radiator Diffuser Thermo King 77-2903 (Fan Shroud) is a critical aerodynamic component that ensures the efficient operation of your transport refrigeration unit's cooling system.

This shroud is mounted directly around the condenser fan and sits flush against the condenser coil. Its primary purpose is to create a sealed air tunnel, forcing the fan to pull air directly and exclusively through the radiator fins. Operating a unit with a cracked, warped, or missing diffuser allows air to bypass the coil entirely (following the path of least resistance). This drastically reduces heat exchange, forces the compressor to overwork, and inevitably triggers high discharge pressure alarms, shutting the unit down. Installing a flawless, OEM 77-2903 diffuser guarantees proper airflow and prevents costly cargo loss during hot summer months.

Manufactured from high-impact, temperature-resistant composite plastic, this shroud maintains its shape under extreme conditions and fits perfectly onto factory mounting points.
