Centrifugal Fans

In short: 19 series (97 models) cover 300–2,500 m³/h, up to 880 Pa static pressure for Centrifugal Fans.

Centrifugal fans deliver high pressure in a compact package. SUNXFAN builds three impeller families — backward-curved, single-inlet and double-inlet — with EC external-rotor motors for 0-10 V/PWM and Modbus speed control. For more product models, please contact us.

Families: 19
Models: 97
Airflow: 300–2,500 m³/h
Motor types: AC / DC / EC

How to choose

Match the impeller to the duct: backward-curved for the highest efficiency at high pressure, double-inlet for wide uniform airflow through AHU coils, single-inlet for compact 120–200 mm installations. Single-inlet and double-inlet wheels are both part of the forward-curved family, suited to medium-low pressure with larger airflows.
