Product Description

What is SIYI fans?
SIYI fan is a type of mechanical fan used in commercial and industrial settings. Unlike residential ceiling fans that are typically 36 to 52 inches in diameter, SIYI fans have very large diameters that start at 12 feet and go up to 24 feet. SIYI fans move very slowly unlike standard fans which operate at high speed. With large diameters and low rotating speed, SIYI fans can move large amounts of air, so it is named "high volume, low speed" (HVLS) fan.
HVLS fans are widely applied in livestock barns, warehouses, distribution centers, shopping malls, skating rinks health clubs and so on. Due to the rising costs of energy, HVLS fans are often used to supplement HVAC systems as they provide a stronger cooling effect while helping to maintain a constant temperature and humidity.

How to work?
The unique airfoil blades on the SIYI fan produce a massive, cylindrical column of air that flows down to the floor and outward in all directions. This horizontal floor jet pushes air a greater distance before it begins to move vertically and is drawn back through the fan. The greater the down flow, the greater the air circulation will be.

IN SUMMER
HVLS fans work on the principle that a breeze moving across your skin on a very hot day feels good. The cool moving air breaks up the moisture-saturated boundary layer (also known as sweat) surrounding the body and accelerates evaporation to produce a cooling effect.
IN WINTER
In a closed space, heat air always gathers on the higher space. That is why in the large commercial space, even if we turn on the air conditioner to the largest point, people on the ground still feel cold. It happened HVLS fans can eliminate the separation of the cold layer and the heat layer and make the heat air circulate well.


Performance
 1, Accelerated Airflow 

     SIYI industrial ceiling fan can bring a large area of gentle breeze blows, achieving a natural three-dimensional airflow.
 2, Dust Removal
    SIYI industrial ceiling fan can achieve environmental dust removal effect combined with ventilation equipment.
 3, Dehumidifying & Cooling

    Keeping the indoor environment dry and reducing the growth of bacteria.
 4, Efficient & Energy-saving
    Low power consumption, saving about 90% energy compared to common small fans.
 5, Safe & Reliable
    Five layers of safety protection measures can ensure that the fan will not fall.

Advantage

Fan Details

Geremany NORD motor
After repeatedly tests, we adopt Germany NORD motor to ensure the low noise, efficient, reliable and durable operation. The motor is free lubrication for life and any potential oil leakage is prevented by the double lip seals.
 

 

DAN-FOSS Controler  
The overload protective device in controller box can automatically disconnect the power supply once accident occurs. So safety is assured. You can regulate the wind speed at will by rotary switch.
