🔹 Ultra-quiet Operation & Safety Guarantee

Noise levels are kept to a minimum with advanced aerodynamic blade design, while multiple safety systems (anti-fall, anti-shake, overload protection) ensure reliable use in all conditions.

Working Principle

The electric motor drives the blades into rotation, resulting in a powerful airflow.

Its operational principle is based on the principles of centrifugal force and gas dynamics. Enclosed within the fan is an electric motor that transmits power to the blades through a transmission mechanism.

As the motor initiates operation, it sets the blades in motion, causing changes in the surrounding air and thus generating wind.

The AirTS-F series large energy-saving fans adopt wing shaped blades, which can minimize air resistance and efficiently convert electrical energy into kinetic energy of the air.

The airflow covers a range beyond the diameter of fan, pushing the airflow vertically towards the ground, forming a 1-3 meter high airflow layer on the ground, thus forming a super large coverage area not only limited to fan size.

Technical Comparison

PMSM VS Gear Shifting Motor

PMSM Motor Advantages:

A. More energy saving

B. Simple structure

C. Smaller size and lighter weight

D. Low noise

E. Frequency range: 0-50Hz

F. Direct drive motor without maintance

Gear Shifting Motor Weakness:

A. More power consumption

B. Complex structure

C. Bigger size and heavier weight, loud noise

D. Frequency range: 25-50Hz

E. Gear shifting motor, the gear should be replaced

AirTS-F Inner VS Outer Rotor

Inner Rotor Structure Advantages:

A. Better heat dissipation: stator is outside (heat source).

B. More safety: the rotating parts are only the motor shaft and fan blades.

C. Longer lifetime: the hanger rod and motor can be integrated as a whole, and the rotating bearings only need to bear the weight of the wind blades, slightly wear.

D. Stable operation: the motor body and fixed steel wire rope are fixed on the motor mounting plate, and the motor does not rotate.

Outer Rotor Structure Weakness:

A. No better heat dissipation: stator is inside (heat source).

B. Less safety: the rotating parts include the motor body and fan blades.

C. Shorter lifetime: single hanger rod, small stress area, and heavy bearing capacity.

D. Easy to shake: the hanger rod bears all the weight of the fan and the torque generated during operation

Standard Control

More Safety and Reliablity

Electrical protection:

lt has protection functions, such as overvoltage, under voltage, loss of voltage regulation, overload, collision, overheating, lightning strike, abnormality, and alarm linkage and so on.

Running indicator light (RUN):

When the light is off, the inverter is in shutdown state; when the light is on, the inverter is in running state.

Keyboard operation, terminal operation and remote operation

(communication control) indicator light (LOC):

.LOC light off: panel start, stop control.

.LOC light on: terminal start, stop control.

.LOC light blink: communication start, stop control.

Tuning, Torque Control, Fault Indicator Light (TUNE):

When the light is on, it means it is in torque control mode. If it flashes slowly, it is in tuning state. If it flashes quickly, it is in fault state.

Optional IoT Control and Wireless Control System

FAQ About HVLS Fan

Q1: What is an HVLS fan?

A High Volume Low Speed (HVLS) fan is a large industrial ceiling fan, typically ranging from 2 to 7.3 meters in diameter, designed to move massive volumes of air at low rotational speeds.

Q2: What is special about the AirTS motor technology?

Unlike traditional asynchronous motors, AirTS HVLS fans use internal rotor permanent magnet synchronous motors. This design reduces heat rise, improves efficiency, extends lifespan, and ensures stable operation.

Q3: What are the main benefits of HVLS fans?

They improve air circulation, reduce humidity, enhance worker comfort, lower energy consumption, and can work alongside HVAC systems to optimize cooling and heating efficiency.

Q4: How much energy can an AirTS HVLS fan save?

With power consumption as low as 1.5kW, AirTS fans can save up to 70% energy compared with traditional cooling solutions. This significantly reduces electricity costs for factories and warehouses.

Q5: Do HVLS fans work with air conditioning systems?

Yes. HVLS fans complement HVAC systems by distributing conditioned air evenly, reducing temperature differences, and improving energy efficiency.

They are widely used in factories, warehouses, logistics centers, shopping malls, gyms, exhibition halls, poultry houses, and farms, where large-scale ventilation and energy savings are needed.

Q11: How does an HVLS fan work in winter?

In winter, the fan helps to destratify air layers by pushing warm air near the ceiling back down, balancing the temperature and reducing heating costs.

Q12: What is the lifespan of an HVLS fan?

With proper installation and maintenance, HVLS fans can last 10–15 years or more, depending on usage and environment.

Q13: How are HVLS fans controlled?

They can be operated via wall-mounted controllers, remote systems, or integrated into building management systems (BMS) for smart operation.
