Roof octagonal fan

Detailed introduction of roof octagonal fan

Introduction to roof octagonal fan:
Drawing on the advantages of similar international products, based on advanced technology, with humanized design and high-performance equipment manufacturing, this product has the advantages of novelty, beauty, high efficiency and energy saving.
1、 Appearance
1. Novelty, beauty, and high mechanical strength
The overall body is made of high-strength and lightweight aluminum magnesium alloy sheet, which has excellent rust and corrosion resistance. The unique octagonal reinforced column structure is designed with excellent mechanical strength, stable overall operation, stronger wind resistance, and better wind guidance effect.
2. Low resistance, smooth ventilation, dust-proof, rain and snow proof
The side outlet design can make the wind direction smoother, reduce the operating wind resistance, effectively reduce the operating load of the motor, and avoid vortex phenomena. The top cover is streamlined to prevent rain, snow, fallen leaves, and other debris from falling in, and is equipped with a gravity check valve to prevent cold air from flowing back during shutdown. The check valve blades are made of aluminum, and the outer frame is made of steel.
2、 Performance
1. High air volume, high air pressure, low noise
The aluminum alloy impeller adopts German technology for special three-dimensional design. The backward inclined impeller is radially installed, and the blade angle can be installed according to actual needs. The impeller is connected to the motor as a whole, making the impeller structure compact, with stronger aerodynamics, and can achieve low-noise operation of the impeller under high pressure conditions.
2. Efficient, energy-saving, and environmentally friendly
Adopting high-quality external rotor motors with strong power performance of the same machine number, selecting motors with low power, high efficiency, low noise, low operating costs, good heat dissipation effect, maintenance free, energy-saving and environmentally friendly, protection level IP54, insulation level F; The motor bearings are selected from Japan's NSK maintenance free bearings. The explosion-proof type adopts an internal rotor explosion-proof motor, with an explosion-proof rating of A.
3. Lightweight
The weight of the fan is only one-third of that of a regular fan, greatly reducing the load-bearing capacity of the roof. Due to its lightweight nature, it also reduces the power of the motor and lowers operating costs.
4. Advanced technology
The aluminum magnesium alloy impeller adopts automatic welding and specialized equipment to ensure the stable performance of the impeller under high-speed operating conditions. All shell parts are cut using CNC equipment
5. Strong aerodynamic performance with minimal flow loss
The cross-section of the impeller inlet Venturi tube is arc-shaped and smoothly transitions with the fan inlet Venturi tube. The fan inlet is formed by spinning and integrated with the fan base to ensure uniform airflow into the impeller inlet cross-section, greatly reducing flow losses and improving impeller efficiency.
3、 Low maintenance costs and long lifespan
1. External swing structure, maintenance free, no lubrication required, low maintenance cost.
2. The designed service life is 20 years, which is 5-6 times that of ordinary fans. The whole machine is made of highly rust resistant aluminum magnesium alloy material, which is particularly suitable for outdoor and harsh environments.
3. Easy to install, flexible, low-cost, vibration free, and can be installed at any angle.
4. Adopting explosion-proof junction box, made of composite engineering plastic, waterproof on all sides, with a protection level of IP54, it is particularly suitable for long-term exposure and harsh environmental use.
