Fan & Cooler Combo Introduction

It’s a combination of HVLS fan and Evaporative air cooler. The concept is to use both the advantages of the two products. With fresh cooled air from air cooler and high volume low-speed air movement from HVLS fan, you will get a perfect environment with the lowest cost; fresh cooled air can be pushed to every corner.

Compare with using only one product, it cost too much for an air cooler to use the ducting system but only gets spot cooling; HVLS fan can make air circulation, but it’s not enough because, in the hot season, people need cooled air.

Fan and more refreshing combo realize a perfect solution for large space cooling and ventilation, no matter indoor or outdoor.


Fan & Cooler Combo Advantage

Why Fan & Cooler Combo Solution works perfectly for large space ventilation and cooling?

  1. The unique advantage of an air cooler is that it can drop air temperature with only 20% power consumption compared to traditional AC, but need air ducting hang on the ceiling which impacts space utilization and image.
  2. The unique advantage of HVLS is the high volume low-speed air movement ability, each fan enable to cover more than 1000 square meters, but can’t get temperature drop;
  3. Fan & Cooler Combo take both advantages and can provide optimized ventilation and cooling environment for users.

How To Install Industrial Ceiling Fans?

Installation Procedure

Step 1: Base Fixed
Clip on any steel H-beam, without changing any steel structure.
Step 2: Cardan Joint
Cardan joint allows the fan to make free oscillation and to find it’s level position no matter what the slope.
Step 3: Extension
Connect the ends of the extension rod with the Cardan joint and drive device by bolts.
Step 4: Mainframe
The drive device has been assembled to be one unit before delivery, fix it to the extension rod by using bolts.
Step 5: Fan Blade
Please ensure the angle between each steel wire and the drive device is 45°,make sure the drive device of fan at a vertical level position.
Step 6: Fan Shell
Take the bottom cover close to the blade wheel and tighten it by bolts.
