Sanwoo HVLS Fans (High Volume Low Speed), also known as helicopter fans, are the ideal cooling solution for large spaces like warehouses and factories. Powered by the latest PMSM motor, they deliver strong airflow with very low energy use. Built with a patented lightweight aluminum chassis, Sanwoo fans are quiet, waterproof, maintenance-free, and come with integrated LED lights.
Key Benefits :
Both our Small Size HVLS Fans and Jumbo Ceiling Fan are ideal for various commercial and industrial spaces such as Factories, heavy industries, logistics centers, industrial facilities, warehouses, outdoor sports courts, open-air malls, supermarkets, automotive workshops, campus halls, school courts/yards, education halls, and farms.
Sanwoo HVLS Fans are a smart investment for businesses looking to maintain a comfortable indoor temperature and fresh air quality. Our High Volume Low Speed Fans offer powerful air circulation with excellent energy efficiency—perfect for large-scale environments.
High volume low speed (HVLS) fans create a gentle breeze by moving large volumes of air at low speeds. This helps to circulate air, enhance comfort, and reduce reliance on HVAC systems.
How they work :
Every part of the Sanwoo HVLS Fan is engineered with precision and built using top-quality materials. From the fan blades to the suspension system, each component is designed to deliver outstanding performance, superior energy efficiency, and exceptional durability and safety.
Below are the key components that define the excellence of Sanwoo HVLS Fans :
Aerospace-level precision on airfoil design.
Adopt imported high-strength aluminum alloy to build a four-rio structure fan wing to improve the safety factor.
Safe suspension device.
Passes SGS certification and can carry up to 500 kg load.
Ultra-quiet PMSM DC Inverter motor.
Using elevator-grade rare earth, and the world’s highest density pure copper automatic wiring technology.
One-piece aluminum alloy chassis.
Adopt World’s first engine shell casting technology.
Smart Temperature and Speed Control
High frequency noise suppression algorithm Ambient temperature sensing, Fully sealed aluminum alloy cooling body,Labor saving and safe wire connector
Embedded structure for the blades.
Innovate exclusive patented fully embedded design, which is safe, strong, and able to withstand any external impact force.
Using one-piece casting technology to build the chassis. The weigh of whole AH-5150 is only about 55kg, which reduces the load of building by a great deal.
Using the patented PMSM (permanent magnet synchronous motor) technology, our motor design is gearless and does not require oil maintenance.
Sanwoo HVLS Fans consume energy 0,26 – 0,74 kWh and Rp390 – Rp1100 Per hour. Covers up to 1,300 m²—no need for multiple small fans. 1 HVLS can replace 10-35 small fans (Compare than small fan 0,15 kWh – 0,2 kWh)
With SGS IP57 certification, the water- proof and dustproof motor is designed with fully sealed tecnology.
Using PMSM gearless motor. The measured noise when the motor on is less than 40dB.
Equipped with the LED lamp, can avoid the afterimage of the light caused by the rotation of the fan blade, and protect the user’s vision without interference.
Ideal for large spaces such as warehouses, factories, gyms, halls, and semi-outdoor areas.
Key Benefits:
Designed for outdoor and commercial spaces that require high durability and reliable airflow.
Key Benefits:

Outdoor food courts, commercial public areas, tourist spots, semi-outdoor halls, and pavilions.
The best solution for confined spaces or areas requiring high flexibility.
Key Benefits:
Recommended For:
Workshops, garages, maintenance areas, outdoor events, dynamic/constantly changing work areas.
Sanwoo HVLS fans (High Volume Low Speed) commonly called a Helicopter fan or Huge Industrial fan, is a large fan with minimum diameter 2.5 m. HVLS fans distribute large volume of air at low rotational speed.
The amount of energy that an HVLS fan uses depends on a number of factors, including the size of the fan, the speed of the fan, and the climate. However, HVLS fans typically consume far less energy than traditional air conditioning systems. Sanwoo HVLS Fans consume energy 0,26 – 0,74 kWh.
The amount of area that an HVLS fan covers depends on the size of the fan. A typical HVLS fan with a diameter of 7.15m can cover an area up to 1300 m2.
The minimum speed of Sanwoo HVLS fans is 25 RPM and maximum speed is 120 RPM for AE series
The warranty on Sanwoo HVLS fan offers five-year warranty on all parts including motor, blades, and controller.
Sanwoo HVLS Fans designed to helps better air sirculation, reduce humidity and enhance comfort in large spaces such as warehouses, factories, schools, churches, hall and various commercial or industrial application.
Sanwoo HVLS fans are efficient because they move large amounts of air and cover large space at low rotational speeds, thus they require less energy than traditional small fans systems to cool a space
The minimum height for HVLS fans is typically 2.5 m for AE series dan 4 m for AH & RCH Series
Yes, HVLS fans can be mounted outdoors because Sanwoo HVLS passed SGS IP57 certification, the water- proof and dustproof motor is designed with fully sealed tecnology. Even if it is intalled in an outdoor open space, there is no need to worry about wind and rain. It can be used both indoors and outdoors.
Sanwoo HVLS Fans (High Volume Low Speed), also known as helicopter fans, are the ideal cooling solution for large spaces like warehouses and factories.
