In order to pursuit of high air volume in a higher negative pressure environment, our company has specially developed a 57-inch high-efficiency fan and a 57-inch high negative pressure fan. Compared with the traditional 52-inch fan, the air volume is increased by 25% at least under the condition of unchanged consumption. At the same time, the material of this fan is 275g aluminum-magnesium-zinc plate, which is highly corrosion-resistant, and central hub and V-Belt pulley are made from die-cast aluminum, with reinforced ribs for prolonged lifetime.

BD-1610 are built with aerodynamic housing with expansion cone. The fan provide high torque performance up to 125Pa static pressure with steady air flow performance across different pressure. The fan is direct driven with IE3-IE4 high efficiency motor.. The fan structure is built in combination of galvanized material and fiberglass blade to ensure better corrosion protection and longer life time!
