Crystal, specializes in crafting bespoke Ventilation fans renowned for their world-class quality, meticulously designed to meet project specifications. Our unwavering commitment to delivering top-notch quality and reliability is the foundation of our mission.

Ventilation fans are essential for maintaining a healthy indoor environment in both residential and commercial spaces. These fans serve the critical function of bringing fresh outdoor air indoors, ensuring proper air circulation, and preventing the build-up of stuffy, oxygen-depleted air. In the absence of ventilation, occupants are forced to breathe in stagnant, less-than-fresh air.

Our Ventilation Fans are engineered to excel, offering efficient air circulation and ventilation. We manufacture them in an AMCA certified, state-of-the-art facility, marked by full vertical integration and equipped with world-class machinery. This guarantees that our Ventilation Fans not only meet industry standards but also exceed expectations, delivering exceptional performance and unwavering reliability for your projects.

Crystal Fans are for custom Ventilation Fans that provide superior indoor air quality, optimal air circulation, and the assurance of world-class quality and reliability at every turn.

CJF Series

Mounted with airfoil blades for great efficiency and low sound, the impellers of jet fans have hubs and blades made of high- strength die-cast aluminum alloys. Each impeller has undergone heat treatment, X-ray flaw detection, tensile test, metal processing and dynamic balancing tests to ensure reliable quality. The blade angles are statically adjustable.

The motor is air cooled, squirrel cage and sealed type resistant to damp heat. It is IP55 rated with Class H insulation; Internationally famous bearing brands are used, such as SKF and NSK; The motor lead wire can be connected to the junction box on the fan stack; The grease tube leading all the way from the grease nipple to the fan housing makes greasing and maintenance much easier.
