A: We are a manufacturer. Our factory was established in 2003, specializing in HVLS Industrial Ceiling Fans, cooling fans, Exhaust Industrial Fans, and related ventilation equipment.

Internal PMSM offers a safer structure:

(1) NdFeB (neodymium iron boron) is inlaid, providing a stable structure.
(2) High Protection Grade, IP64.
(3) The installation has 5 force-bearing points, keeping the fan stable during external force interference.

External PMSM has a less safe structure:

(1) NdFeB (neodymium iron boron) is fixed by glue, which can easily fall off.
(2) Motor contains heat dissipation holes, making it unable to prevent water and dust ingress.
(3) Wire rope is installed on the central pole, with all bearing points situated solely on the pole.

(1) Brand internal rotor PMSM ensures reliable quality control.
(2) High-quality motor matches perfectly with our special design blade, delivering high efficiency with low energy consumption.
(3) Blade research and development done with a professional research institute, producing a comfortable, natural wind feeling.
(4) Intelligent integrated control system supports controlling up to 48 sets of fans simultaneously.
(5) Multi-tiered safety structure.
(6) Excellent after-sales service including a 5-year warranty.
