High Static ESP Ducted Fan Coil


The Polar Air high ESP ducted fan coil units have been specifically designed for high cooling capacities and high external static pressure applications.


The Polar Air High ESP ducted fan coil units have been specifically designed for high cooling capacities and high external static pressure applications. The units are a cost effective solution to providing comfortable airflow for both commercial and residential applications. With quiet operation, compact dimensions and low heights, these units are ideal for limited ceiling space.

The Polar Air High ESP ducted fan coil come in a range of AC and EC motor 230V/50Hz units.

Standard Configuration

The ducted high series offer standard nylon net filters.
