Electric SF Duct Axial Flow Smoke Extract Fan with Ball Bearing

SF/SF(B) Type Fuct Axial Flow Fan

Product introduction:

  SF duct axial flow fan achieves indoor cooling through negative pressure ventilation and water evaporation, which can break the thermal inertia of greenhouse air to the greatest extent, better maintain the stability of indoor microclimate, and fully realize full automation. It has good cooling, air supply and ventilation effects, is easy to operate, clean air, and has multiple installation methods. It is an economical and efficient cooling method.

Product features:
1. High efficiency and energy saving
Adopting 100% pure copper motor and double ball bearing and other internationally advanced energy-saving technologies and automatic thermal protection systems to ensure product safety and stability while reducing resistance and minimizing energy consumption.

2. Low noise
The fan blades are designed and manufactured according to the three-phase flow theory. The airfoil blades can be adjusted to achieve a variety of flow and pressure configurations, with large air volume and low noise.

3. Anti-corrosion and moisture-proof
The new bearings produced by precision technology have excellent wear resistance and corrosion resistance, are not easy to rust, have bidirectional stability, and are not afraid of impact during long-term high-speed operation. The cast iron shell and blade surface are sprayed with high-temperature powder, which is moisture-proof and durable.

4. Long service life
Adopting anti-corrosion and non-deformable stamping blades, thickened steel plates, double screw reinforced motors, high heat dissipation cast iron shells, double ball bearings, safe and durable, with a service life of more than ten years.

5. Various installation methods
According to the different needs of product usage scenarios, various installation methods such as hanging installation, fixed vertical installation, adjustable vertical installation, embedded installation, etc. are adopted, which are simple to operate and easy to install and disassemble.

Application areas:
1) Industrial field: textile, socks/clothing, glass, mold, rubber, spraying, screen printing, toys, electronics, home appliances, shoemaking, printing, food processing, dyeing, laundry and other high temperature workshops.

2) Civil field: Internet cafes, shops, supermarkets, canteens, vegetable markets, waiting rooms, entertainment venues and other places that require air conditioning.

3) Agricultural field: large farms, greenhouses, livestock farms, etc.

The place of use does not contain flammable, explosive or corrosive gases, and the temperature shall not exceed 60℃.
