Introduction
Double Inlet Forward Curved Centrifugal Fan is a highly efficient air supply device, suitable for large ventilation and air delivery systems.
Features
Double Inlet Structure
The fan adopts a symmetrical double inlet structure, which can inhale air from both sides of the impeller at the same time, greatly reducing airflow resistance, with a maximum air volume of 500,000 m³/h and a more uniform airflow distribution.
Efficient and Low-noise Operation
The Double Inlet Forward Curved Centrifugal Fan is equipped with a multi-wing forward curved impeller with dense blades and high cutting frequency. It can achieve a high static pressure (500–5000 Pa) at medium speed and effectively reduce operating noise.
Small Footprint
The double inlet design shortens the overall fan length, and the impeller and motor are arranged symmetrically on the same axis. The installation volume of the device is 20%–30 % smaller than that of a single inlet fan with the same air volume, which is convenient for embedded installation or equipment integration.
