BDWT-I-7 Explosion proof BT4 Fiberglass Roof Axial Flow Exhaust Fan

DWT-I roof axial flow fan is a common ventilation fan installed on the roof. It is a special type of axial flow fan in the category of axial flow fans, and its working principle is the same as that of axial flow fans.Explosion proof and sand proof fiberglass roof axial flow exhaust fanComposed of impeller, air duct, air cap, transmission components, loose leaf air door, bird proof net, safety net and other parts. The wind duct, wind cap, and impeller components of this fan can be made of fiberglass, which reduces the overall weight of the machine and has good corrosion resistance. According to the different requirements of wind volume, wind pressure, and noise in the application, the following two forms of fans are selected: (1) Axial flow roof fan, code named DWT-I type, with the characteristics of large air volume and lower pressure than centrifugal fans; (2) Centrifugal roof fan, code named DWT-II, is suitable for situations with low air volume and high pressure requirements.
Purpose: The DWT series low-noise roof fan is widely used for air supply and exhaust in light industrial workshops and high-end civil buildings, especially for the discharge of humid and corrosive gases. The medium temperature does not exceed 60 ℃, and excessive viscous substances are not allowed in the gas. The dust content is less than 100mg/m3.
Specification: Axial flow roof fan specification DWT-I type Axial flow roof fan number: 3 # -24 # Air volume: 1450-220800m3/h Total pressure: 62-330Pa
Characteristics of DWT-I axial flow roof fan: high air volume, low noise, high efficiency, light weight, smooth operation, beautiful appearance, can be made into anti-corrosion and explosion-proof types
BDWT-I-7 Explosion proof BT4 Fiberglass Roof Axial Flow Exhaust FanApplication: Air supply and exhaust for power plants, chemical, rubber, pharmaceutical, food processing, metallurgy, warehouses and other industrial and mining enterprises, as well as high-end civil buildingsThere are multiple specifications and a wide range of applications: Three types of fans can be selected according to the different requirements of usage, air volume, pressure, and noise:
Axial flow roof fan: model DWT-I, suitable for medium and low pressure, high flow applications. According to user needs, it can also be designed as a bidirectional reversible air supply and exhaust fan, which has the equivalent characteristics of forward and reverse working conditions, such as DWT-V type
Centrifugal roof fan: available in two types: DWT-II and DWT-III, suitable for situations with low air volume and high pressure requirements;
◆ Non motorized turbine exhaust fan: Model DWT-IV, it is an ideal energy-saving ventilation device that is driven by the difference in indoor and outdoor air, with special arc-shaped blades rotating along the axis to exhaust indoor air.
High efficiency and low noise: This fan adopts CAD software and is designed through multi-objective optimization. There are a total of eight types of wind turbines in the DWT-I series, numbered 12 # -24 #. By changing the speed, angle, and blade shape, the performance parameter range is expanded to meet the needs of different operating conditions, achieving fan system matching for energy saving and noise reduction;
◆ Stable operation and long service life: This fan has a small moment of inertia, high dynamic stability accuracy, and smooth operation. The requirements of the enterprise's internal control standards for various performance indicators are higher than the industry standards for fans, ensuring that the fan is in the best position among peers;
◆ Wide applicability: This fan can be made into explosion-proof, anti-corrosion, and suitable for forced exhaust in flammable, explosive, and corrosive gas environments according to usage requirements;
This product has passed multiple provincial and municipal technical supervision and testing, and users can choose it with confidence. The parameters and actual photos of the BDWT-I-7 explosion-proof BT4 fiberglass roof axial flow exhaust fan are as follows:
