Product Q&A

Q:Are you a foreign trade company or a manufacturer?

We are a manufacturer. Our factory was established in 2003, specializing in HVLS Industrial Ceiling Fans, cooling fans, Exhaust Industrial Fans, and so on.

Q:HVLS fan is joint launched with GREE, what is GREE?

GREE is short for GREE Electric Appliances Inc of Zhuhai, founded in 1994 and listed on the Shenzhen Stock Exchange in November 1996. It is a Global Top 500 enterprise and the best air conditioner producer in China. The motor is produced by GREE's motor production department, which is also famous for industrial motor production.

Q:Why use GREE internal rotor PMSM? What's the difference with external rotor PMSM?

Internal PMSM offers more safety: (1) NdFeB is inlaid with a stable structure. (2) High Anti Grade IP64. (3) Installation has 5 force bearing points for stability under external force. External PMSM has less safety: (1) NdFeB is fixed by glue and easy to fall off. (2) Motor has heat dissipation holes, unable to resist water and dust. (3) Wire rope installed on the central pole with all bearing points only on the pole.

Q:What's the advantage of your HVLS industrial Ceiling fan?

(1) GREE brand internal rotor PMSM for quality assurance. (2) Good quality motor perfectly matched with special design blades for high efficiency and low energy consumption. (3) Blades R&D with Gree Research Institute for big and comfortable natural wind feeling. (4) Intelligent integrated control system, maximum control of 48 sets of fans at the same time. (5) Safety structure. (6) Excellent after-sale service with 5 years warranty.

Q:How do you do after-sale service?

We will send you free spare parts to replace under warranty.
