SY-WBTD Roof Exhaust Fan

Brief Introduction

The main components of the roof fan are made of FRP (Fibre Reinforced Plastic) materials. The impeller utilizes advanced airfoil blades, which reduce the weight of the rotating parts and thereby meet the requirements for aerodynamic performance. The outer surface is coated with gel coat resin, ensuring a smooth finish, aesthetically pleasing appearance, lightweight design, low noise levels, corrosion resistance, and excellent vibration performance. These features contribute to stable and reliable operation, energy efficiency, and explosion-proof characteristics.

This ventilator consists of various components, including impellers, a hood, a motor, a rectifier ring, protective nets, loose-leaf dampers, and safety nets. The rectifier ring is a unique structural form designed to enhance the efficiency and reduce the noise of the roof fan. Additionally, the loose-leaf damper and safety nets can be customized according to customer requirements.
