HVLS is HIGH VALUME,LOW SPEED fan, Super large variable frequency control fan. The HVLS 24ft large fan was born in 1995 in the USA.
It is designed to save energy and reduce consumption of tall builings and improve the working enviroment.
Design 6 road safety devices to ensure foolproof.
HVLS fan using Rexroth inverterwhich is the most famous inverter in worldwide.
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. What's more, the inverter can control
the fan to rotate in forward and reversing direction.
1.Low backlash assembly process and gear grinding technique,lower noise
2.Strength the bearing frame structure,increase oil seal and strength the
motor structure with trapezoidal shaft structure,higher safety
3.Passed CCC,CE,UL certificates
Aluminum alloy fan blade
The blade is the core technique of the fan. We use simulation software ANSYS
to make the blades with most reasonable transversal surface and inner limiting
plate. HVLS fans have 6/8/10 PCS of blades and winglets to ensure maximum
airflow and efficiency. Unique designed winglets at the airfoil tips greatly
eliminate wind noise. The blades is made of aluminum alloy with plastic
spraying finish, so it can resist corrosion and dust very well.
HVLS ceiling fans, but “how big” and “how many” are important questions. The fan size and the number of fans needed in a particular space depend on many things including the building’s size and use. Because choosing the correct fan(s) for an application is complex, it is best to request an airflow simulation.
