DWT Series Axial Flow Roof Fans for Workshop Ventilation
The roof fan has many specifications and forms, and has a wide range of applications. It can be used according to the different requirements of air volume, pressure and noise.
Usage Environment
The roof fan is installed on the roof for ventilation. Due to the particularity of the installation environment, the material and structure of the fan are special. The roof fan is equipped with a device to prevent air backflow after shutdown. Due to the high-speed rotation of the fan under the action of hot pressure, the wind speed in the air duct increases a lot, and the fan reverse is very unfavorable to the start of the motor, which may be damaged due to excessive starting current.
The roof fan should be designed with reliable performance of rain proof, snow proof and sand proof. Snow and sand are not like rain, because snow and sand will not only enter the fan from the upper part, but also enter the fan from the lower part when the outdoor wind speed reaches a certain intensity.
Performance
Using advanced CAD software, through multi-objective optimization design. There are eight kinds of fans in dwt-i series. The method of changing the speed, angle and blade profile is adopted to expand the range of performance parameters to meet the needs of different working conditions, so as to achieve the matching between the fan and the system, so as to realize energy saving and noise reduction. Stable operation, long service life, small moment of inertia, high dynamic stability, high precision, stable operation, and the requirements of various performance indicators in modern enterprise standards are higher than the fan industry standards, to ensure that the fan is in the leading position in the industry. The fan can be made into explosion-proof type according to the use requirements. It is suitable for forced ventilation in flammable, explosive and corrosive gas occasions. It has been tested by the provincial and Municipal Bureau of technical supervision for many times, and users can use it safely.
