PSX Series

Exhilarating Performance
Operating on the epitome of HVLS motor technology, the PSX series runs on Permanent Magnet Synchronous brushless direct drive motor (PMSM) offering 30% increase in airflow, amazing torque balance, 15% reduced noise level and high transmission efficiency.

Aerofoil Blades
Our aerofoil blades are made of aviation grade magnalium (magnesium alloy) and finished in fluorocarbon coating to withstand the toughest environment. It’s unique patented design structure is further strengthened with 3 vertical stiffeners within the length of each blade to avoid structural fatigue.

Totally Free of Maintenance
Different from gear technology products using regular replacement of lubricating oil in gearbox, the PSX series PMSM motor, based on the principle of electromagnetic induction and double bearing transmission, is completely sealed and truly free maintenance. No more costly gearbox maintenance visits and no more oil leakages.

Aero Winglet
A winglet is attached to a distal end of the aerofoils to reduce drag and improve downward lift, creating up to 40% more air than most of our competitors.

Excellent Coverage
The super large air volume and coverage area brings comfortable natural breeze and make the working environment change positively. It can, not only directly cool the human body, but also bring the whole area excellent ventilation and efficient dehumidification and moistureremoval effect.
