If the return air space is insufficient, the pressure difference between the blades 91 will be greatly reduced, resulting in a lack of air flow. Most of the indoor space has its inherent height limit, so its safe height (the bottom of the fan blade to the floor height of 210cm) and the best working space (fan blade to ceiling height > 50cm) become a limitation in use, and The exposed fan blades are prone to the threat of oppression and the glare of light reflection.
