Welcome all to my profile page! My name is Quinn Thompson and I live in the USA. The HVLS (High Voltage Low Speed) fans are more powerful, efficient and reliable than traditional ceiling fans. They have a higher rotational speed of 1,500-2,000 RPM's while the traditional ceiling fans rotate at only 250 RPM's. The high voltage is provided by a transformer which is installed inside the box or plate mounted on the ceiling. The blades of HVLS Ceiling Fans are made of high quality steel with a special coating to ensure smooth operation.
