Natural Power Motorless Roof Ventilation Fans,
Poultry Environmental Control System


Natural Power Motorless Roof Ventilation Fans Introduction

Natural power motorless roof ventilation fans are widely used in poultry farms, due to zero-cost operating costs, considerable energy efficiency, economical installation costs, and low maintenance costs. Its working principle: Turbine ventilators use natural wind and air thermal convection caused by the difference between indoor and outdoor temperature to push the turbine to rotate so as to use centrifugal force and negative pressure to expel the stale indoor hot air.


Natural Power Motorless Roof Ventilation Fans Techinical Parameter

Natural Power Motorless Roof Ventilation Fans Features:

1. Generate air convection and exhaust heat.
2. Reduce air conditioning load and increase indoor fresh air.
3. Exhaust roof moisture, mildew, and steam, and keep the roof dry.
4. Replace heavy-duty electric exhaust fans, reduce bracket costs, save electricity bills, and reduce noise.


Special Energy Efficiency

1. The curved blade is the best result of scientific calculations, which can strictly guarantee that rainwater will never invade under working conditions. The exhaust efficiency is high, as long as the temperature difference is not less than 0.2 meters or the temperature difference between indoor and outdoor exceeds 0.5℃, it can operate lightly and effectively.
2. The central axis is equipped with fine steps, so that the blades of the turbine will never be deformed under high-speed operation, thereby greatly improving the service life of the ventilator.
3. The design of the variable-angle neck tube allows the fan to be installed as desired under a slope of 0-22.5 degrees. The installation project is very simple, and the average person can install it in about 30 minutes.
