An Exhaust Turbo Fan, commonly known as a Turbo Ventilator, is a mechanical device used to enhance air circulation by extracting stale or hot air from industrial, commercial, and residential spaces. These fans utilize wind or mechanical energy to rotate, creating a vacuum that pulls out the indoor air and replaces it with fresh air from outside. The primary purpose of an exhaust turbo fan is to improve indoor air quality, reduce heat, and control humidity.
