Description & Features:

    • Introducing the PSX Series! This fan is the pinnacle of performance, quality and overall value. Powered by the latest technology in advance gearless drive, the NeoDrive PMSM motor wield an unmatched airflow performance. You get more than a fan; you get one of most versatile cooling solutions available in the market.
  1. Powerful Performance (Epitome of Direct Drive Motor)
    • The AireGard PSX series is the most powerful HVLS ever created in our range of product. Delivering an extraordinary airflow of more than 522,000 CFM, it is the best solution for your space while offering excellent torque, efficiency and durability. Powered by our patented direct-drive NeoDrive PMSM motor with innovation in mind, this motor needs no maintenance and absolutely quiet.

    • Different from gearbox fans, our PMSM motor requires no traditional oil changes. No more costly-maintenance and messy leakages.


3. Excellent Coverage (Air Ventilation Solution)

    • The large air volume produced and ventilated by our PSM Series brings unmatched cooling performance, delivering massive airflow to cool your extra -large spaces. Our gearless design makes it whisper quiet.


4. Aerofoil Blades (Generating High Air Circulation)

    • Our areofil blades are made of aviation grade magnalium (Aluminum 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.


5. Aerofoil Winglet (Boost Airflow and Drag Reduction)

    • 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.



    • Zero-maintenance.
    • Higher control accuracy and torque density.
    • Lower noise.
    • Higher efficiency and power factor.
    • Lower temperature rise.
    • Higher fan speed range.
