The Polar Air Horizontal Mini AHU fan coil units have been specifically designed for horizontal installations. With sandwich panels to achieve low noise levels, integrated control box and panels to access components, these units are a cost effective solution that provide a comfortable environment for both commercial and industrial applications.

Units are delivered completely assembled with the motor wired into the control box, reducing on-site installation time and labour costs. The units contain side panels which provide easy access to fans, motors, and filters.

The Polar Air Horizontal Mini AHU fan coil has a range of AC and EC motor 415V/3Ph/50Hz units.

Standard Configuration

The Horizontal Mini AHU Series offers a standard 25mm nylon net filter and the option to choose left or right side coil connections.
