Time to Upgrade your Ventilation

Still, ventilating with rows of small wall fans? For customers who are using dozens or hundreds of small wall-mounted fans, we will provide a detailed ventilation cooling solution.

Core Technology

Motor Frame

"mortise and tenon joint structure" welded by the robot, traditional technique with a double guarantee on Q345B high-strength structural steel.

Safety Retainer

6 pcs airfoils are connected into a whole with 6 pcs safety retainer.

Fasteners

German DIN933 Industrial Bolt and DIN125A lockut with high strength 8.8 grade, the practical stress it could endure is 10 times than normal.

Cardan Joint

Unique cardan joint design, working as a human being’s joint, allows the fan to find its own vertical position no matter what the slope of the building, and helps to decrease the shock of the fan during running.

Installation Kit

  • Particular no-skip flute design and locknut to prevent any accident of installation kit;
  • Adjustable standard clip device without the need to change the structure of the building.

Fan Blade

  • High strength aircraft aluminum alloy: AA6063T6511 PVFD processed on the surface;
  • Patented airfoil design, and special reinforcing rib support system which increases the strength of fan blade and avoids the sagging of fan tail and fatigue loss of connecting components;
  • Customized fan blade color

Hub Wheel

  • Imported Aeronautic Aluminum Alloy (AA7075);
  • Unique Double Wheel Hub design;
  • High pressure forging technology, with T6 thermal treatment process & CNC precision machining & dynamic balance test of the complete set chassis & 40 times strength test.

Controller

  • Denmark imported a "DANFOSS" VFD(Variable Frequency Driver) inverter;
  • IP55 motor protection grade and NEMA 1 standard control box “Schneider” brand electrical sets, with safety protection;
  • module inside which will interrupt the output automatically in case of some accidents.

Driving Device

  • German imported "NORD" coaxial bevel wheel decelerator with a diameter of axle 40mm to decrease radial force;
  • German imported"Simrit" double oil seal design, more durable and reliable;
  • "Shell" brand top class "Omala" S4 lubrication oilZero maintenance for over 20,000 hours;
  • IE2 high efficient motor with imported"SKF-VL" bearing, save more 5~10%than IE1.

THE ENERGY-EFFICIENT FAN OF YOUR DREAMS

Powerfoil Breeze knows when to spin and when to stay quiet—thanks to this commercial fan’s infrared motion sensor that automatically detects when people are active in your space and when they’re not. (And turns off after five minutes if your space is a ghost town!)
