Fan & Cooler Combo Introduction

It’s a combination of HVLS fan and Evaporative air cooler. The concept is to use both advantages from 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 distributed to every corner.

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

Fan and cooler combo realize a perfect solution for big space cooling and ventilation, no matter indoor or outdoor.
