Description
This HVLS(High volume low speed) fan is driven directly by PMSM(Permanent magnet synchronous motor),there’s no gearbox transmission between the motor and the impeller , it’s high efficiency and totally maintenance free.
The traditional HVLS fans is an Induction Motor/Gearbox system, efficiency is low, gearbox need maintenance and is not reliable, the height of traditional HVLS fan is much higher than the PMSM HVSL fan, the motor position and the gravity center is above the fan blades, easily cause shaking due to the gravity center of the system is much higher than the blades,
This HVLS PMSM fan system can create constant airflow to reduce perceived temperatures by 9-12°C, Reduce energy costs up to 30% by minimizing the temperature differential from the ceiling to the floor, it can:
• Maintains comfort levels throughout building
• Improved employee comfort
• Noise level close to an average library
• Reduce existing HVAC units run time and reduce cost
| Model | Voltage | Fan diameter | Motor model | Motor Power(W) | RPM | Current(A) | Volumn M3/min | G.W（KG） | Cover Area | Noise |
| TCF73 | 220V | 7.3M (24′) | M300 | 1500 | 0-60 | 5.9 | 12500 | 125 | 1600 | 35 |
Advantage:
1、High Efficiency: up to 85%
2、Energy saving: Up to 30% energy saving by combining HVAC(Heating Ventilation and Air Conditioning) with HVSL Fan system
3、Low Noise: 35dBA
4、Reliability: Direct drive, no gear box. Much reliable than traditional induction motor/gear box system, 100% maintenance free
5、Installation Height： height much less traditional Induction motor/gearbox system，can fit low ceiling
6、Safety:
*Motor gravity center much lower than traditional Induction motor/gearbox system, more stable during running
*Safety structure in motor, ensure no falling down even if screw loose
