Centrifugal roof fan

Axial flow roof fanIt is an axial flow fan with a simple structure, low noise, and rainproof function. The following are its main features:

Structural characteristics

Impeller design: Adopting a wide blade and large chord length space twisted and inclined blade shape, this design enables the fan to achieve the required air volume and pressure at low speeds, effectively reducing fan noise. At the same time, the impeller is directly connected to the motor, which can transfer the energy of the motor to the air as much as possible and improve the working efficiency of the fan.

Diversion device: usually equipped with wind and rain caps, diversion rings, and other components. The wind and rain cap can prevent rainwater from entering the interior of the fan and protect the electrical components of the fan; The guide ring can evenly introduce gas into the impeller, reduce intake vortex loss, and further improve the efficiency of the fan.

Shell structure: Generally welded from plates or profiles, it has high strength and stability, and can withstand various forces during the operation of the fan. Bird nets and other protective devices will also be installed to prevent birds and other debris from entering the fan and affecting its normal operation.

Axial flow roof fanPerformance characteristics

High air volume: able to work within a large flow range, meeting the ventilation and air exchange needs of different places, such as factory workshops, large warehouses, sports venues and other places with dense personnel or high equipment heat dissipation requirements.

High efficiency: Compared to other types of fans, it can deliver more air at the same power, with good energy-saving effect. Long term use can reduce energy consumption costs.

Moderate pressure: The generated pressure can meet general ventilation requirements and is suitable for air transportation and exchange in most buildings and industrial sites.

Low noise: By optimizing the impeller design, using low-noise motors, and reasonable pneumatic layout, the noise generated during fan operation has been effectively reduced, providing people with a relatively quiet working and living environment.

High temperature resistance: It can work normally in high temperature environments and is suitable for places with special temperature requirements, such as ventilation and air exchange in drying rooms.

Application features

Easy installation: Due to its relatively simple structure, light weight, and convenient installation process. According to different installation requirements, horizontal installation, side wall horizontal installation, or suspended installation can be selected.

Easy maintenance: Daily maintenance work mainly includes regularly checking the operating status of the fan, cleaning the impeller and casing surface, lubricating bearings, etc. The maintenance cost is low and easy to operate.

Strong adaptability: It can be customized according to different usage environments and needs, such as explosion-proof, anti-corrosion, variable frequency speed regulation and other types, to meet the requirements of special places.
