Why use a industrial High Volume Low Speed fan?


High-Volume-Low-Speed fans are equiped with special motors, controllers and sometimes gearboxes to provide a high torque at low speeds. These fans are designed to be Durable, Quiet and Efficient. 

To cover any large area above 200m2 with regular fans would require many small fans.

Why does a fan make difference?

A fan makes it 'feel' up to 8 degrees cooler because of the evaporative cooling effect. When air flows over the skin a heat exchange takes place between the human body and the environment. This amount of heat exchange depends on temperature, humidity and air flow over the skin surface. Test shows that significant skin cooling is achieved at wind speeds of 0,6m/s or 2km/hr. 

Using an industrial fan in Vietnam

With an average temperature in Ho Chi Minh City around 30°C having a good fan is a must.
With land prices, energy costs and salaries increasing large spaces efficiently and keeping everyone productive having a constant airflow over the entire floor is important.

A few tips for keeping Factories and Warehouses cool in Vietnam

Heat reflective paint

1. Heat reflective paint reduces the temperature caused by solar heat. The paint is designed to reflect the sunlight. This effectively reduces the temperature of your factory.


Roof insulation


Bubble foil or fiber insulation ensures that the heat doesn't get in and infra-red heat from the roof is kept out or the building. 

Roof ridge fans

Roof ventilators are turned by the wind and are a good solution to extract hot air from the building.  Roof ventilators are available in many qualities and sizes. 


Ridge vents


Ridge vents are designed to exhaust hot air that is already inside the building. Simply allowing hot air to rise up through them rather than pushing it out as a fan does. 

HVLS (High Volume Low Speed) fan

One of the most cost-efficient possibilities to reduce the factory floor temperature is the use of a ceiling fan. A big ceiling fan provides a continuous air flow. This stimulates evaporative cooling on the skin and the feel like temperatures decreases.
