It is fitted with an automatic drop hammer shutter system. The shutters open automatically under airflow when the fan runs, and close tightly by gravity once power off, effectively preventing cold air backflow, dust and insects from entering the room, realizing automatic sealing without manual operation.
With stable negative pressure air output, this 800mm exhaust fan quickly discharges accumulated heat, water vapor and harmful gases inside the space. It can cooperate with evaporative cooling pads to build a complete cooling ventilation system, helping maintain ideal temperature and humidity for livestock and crops.
Compact in overall dimension, easy to install and maintain, this 800mm drop hammer fan supports long-time continuous operation. It is also suitable for small workshops, storage rooms and other spaces requiring air exchange, available with OEM & ODM service to meet your customized demands.
