Low Noise and High Air Volume Fan for Engine Cooling is available in a wide range of application including all machinery. Its excellent performances can meet cooling requirements of most types of engines. It has low noise and big air flow.
Introduction ▼
The 7Z Series Industrial Fans provide high-efficiency ventilation solutions, engineered to deliver superior airflow performance with reduced noise and energy consumption. Building on the proven sickle-blade technology of our S-Type series, the 7Z fans feature an enhanced blade design that achieves even greater static pressure (up to 45% higher than conventional fans at certain flow rates) while maintaining ultra-low noise levels (4-6 dB reduction).
■ More efficient
■Less absorbed power
■ Low noise
■ Light weight High strength
■ Preservative
■ Customization
Blade ▼
To ilustrate the advantages of sickle-blade fans, we compared them with the traditional wina fans. The diameter of the two fans is 700 mm and the rotating speed of the fans is 710 rpm. When the two fans reach the same operating point, the folowing advantages are obtained by testing compared with the sickle-blade fans.
■ High-static pressure
■ Low noise
■ High efficiency
