Product Q&A

Q:Are you a manufacturer or trading company?

We are a manufacturer established since 2003, specializing in HVLS Industrial Ceiling Fans, cooling fans, and exhaust industrial fans.

GREE is GREE Electric Appliances Inc of Zhuhai, a Global Top 500 enterprise. KB Motor is its motor production department, providing the internal rotor PMSM for our fans.

Q:Why use GREE.KB internal rotor PMSM instead of external?

Internal PMSM offers more safety with inlaid NdFeB, IP64 protection, and 5 bearing points for stability. External rotors use glued NdFeB, lack dust/water protection, and have single-point bearing support.

Q:What are the main advantages of your HVLS industrial ceiling fan?

Advantages include GREE.KB internal rotor PMSM quality, high efficiency with low energy consumption, comfortable natural wind from R&D blades, intelligent control for up to 48 fans, safety structure, and 5-year warranty.

Q:How do you handle after-sale service?

We provide excellent after-sale service with a 5-year warranty, sending free spare parts for replacement under warranty.
