The product is compact in structure, with depth as low as 470 mm and thickness as low as 230 mm. It is especially suitable for restricted ceiling space and can save building floor height.

Highly efficient brushless DC motor is used with low wind resistance energy-saving heat exchanger to achieve higher efficiency. During operation, the energy consumption can be greatly saved during low load period through stepless regulation of speed.

The motor features UHF drive emitting only very low noise, and the fan adopts large impeller achieving low speed. Selected noise insulation materials are used with unique intelligent mute control logic, so that the operating noise can be as low as 20 dB (A).

The pan is formed using one-off processing technology without any welds and processed with anti-corrosion treatment; The thermal insulation material at the bottom has no joint and no condensation problem. The fire protection rating is non-flammable, so it is safe to use.

The user can quickly convert among external static pressures 12Pa, 30Pa and 50Pa through a DIP switch at the installation site to meet different applications.
