LEO H is a series of industrial HVLS (High Volume Low Speed) ceiling fans, which allow to pump large volumes of air at the same time with low rotor speed and low power consumption. Their main function is to destratify and create an apparent cooling and heating effect.
The fan operates in a capacity range of 117,000 to 780,000 m3/h, with an electric power consumption of up to 1.5 kW and a speed of up to 55 rpm. LEO H is an efficient HVLS(High Volume Low Speed) industrial fan that is capable of pumping large volumes of air while consuming low electricity.
Thanks to its unique design and advanced algorithms, this fan is capable of pumping between 117,000 and 780,000 m3/h of air at an electrical consumption of up to 1.5 kW and a speed of up to 55 rpm.
Basic parameters
| Diameter | up to 7,3 m |
|---|---|
| Coverage | up to 1300 m2 |
| Speed | up to 55 rpm |
A powerful motor with low power (1.5 kW) and high efficiency (over 90%) consumes a small amount of electricity.
High-quality design, reliable electric motor and adequate thickness of materials contribute to the high efficiency of the device.
Simple automation allows easy operation of the fan.
Reduced cost of traditional (or existing) cooling/heating.
Functionality of HVLS devices
Destratification
The primary function that the LEO H fan performs is to set air in motion and mix it throughout the room. Through this process, the temperature differences between the air at floor and ceiling level are balanced out, effectively preventing heat loss and providing a more comfortable temperature inside the room. The fan also prevents the formation of so-called "dead zones", i.e. zones in which the air does not move.
Heating effect
Also referred to as "apparent heating", it involves moving the warm air masses stored under the ceiling downwards to a lower zone, which leads to an equalisation of the temperature gradient in the building. This results in a significant reduction in energy requirements for reheating the facility. The prerequisite for this effect is that the hall is adequately heated.
The cooling effect
Also referred to as "apparent cooling", involves moving the air masses accumulated under the ceiling downwards to a lower zone, resulting in a "draught" effect and thus apparent cooling. This results in a significant reduction in energy requirements for conventional cooling of the facility, such as through air conditioning. This effect is also achieved when air with a higher temperature than that currently in the cooled zone is pumped.
Application
The wide range of types of the LEO H fan allows the device to be used in many types of facilities, such as: industrial facilities (production halls, industrial halls, factories), logistics facilities (logistics centres and warehouses), sports facilities (football stands, tennis courts, gymnasiums), large-area halls (trade fair halls, large-area offices, exhibition halls). In addition, it can be used in special designs, e.g. in livestock facilities.

The LEO H fan is mounted to the ceiling with suitable accessories for various types of surfaces. First, a mounting bracket is installed, to which the core with the motor is attached. If necessary, it is also possible to use an extension element between the handle and the motor. In the third stage, the fan blades are attached to the core with the motor. The final step is to install the stabilising cables and connect the control and power system.
