Ultra-quiet Cooling Tower fan

Airfoil-shaped hollow blade fans are made from Aluminum extrusion alloy. Fan hubs are fabricated from hot-dip galvanized (HDG) circular plate with epoxy coated cast iron core and Aluminum blade camps. The fan blades are adjustable in pitch to allow for maximum utilization of rated horsepower and optimum performance.  Each cooling tower with 3-layer Fan, a total of 21 blades, speed is 120 RPM, the wind can meet the noise is very low.High efficient lower tip speed and light weight design ensure low power consumption and low noise level, thus and guarantee 100% performance.The fan is used in cooling towers that require noise, or used to reduce noise in cooling towers, and the effect is very good.a9QCooling tower noise reduction treatment manufacturer
The fan is a dedicated fan for low-speed space-distorted double-layer aluminum alloy airfoil cooling towers. Fans include ordinary 4-blade fans, 6-blade low-noise fans and 8-blade ultra-low-noise fans. Select high-quality aluminum alloy sheet press forming, all fans are adjustable angle type, can meet the different requirements of customers on air volume and other technological aspects. The fans are strictly balanced and positioned before leaving the factory to ensure the reliability of their performance. The surface of the fan is treated with secondary high-adhesion spraying and anticorrosive treatment, which meets the GB/T9286-88 standard. The fan performs ZBJ72042-90 balance accuracy check. It has large air volume, low energy consumption, low noise, uniform outlet wind speed, small vibration, and air volume. Tune and other advantages.a9QCooling tower noise reduction treatment manufacturer
