Ventoptek launches the TF-1380 variable-speed exhaust fan. Developed as an upgraded iteration based on the proven Malido TF-1380 model, it retains the classic 50-inch external dimensions and is equipped with a direct-drive permanent magnet motor to deliver stepless speed regulation, enabling precise ventilation management for large-scale livestock farms.

The fan allows flexible airflow adjustment according to indoor house temperature, covering a wider range of ventilation operating conditions. For broiler farming applications, it is recommended to install an additional 2–3 units of TF-1380 alongside existing conventional ventilation systems to expand the ventilation adjustment range and address the pain point that traditional fixed-speed fans struggle to adapt to low-air-volume operating conditions.

This unit is perfectly suitable for critical farming modes including brooder ventilation for chicks, nighttime low-temperature air exchange, and minimum winter ventilation. During the brooding phase, low-speed stable air exchange prevents cold air from blowing directly onto young chicks. Under minimum ventilation mode in cold winter, continuous low-speed operation balances heat preservation and air renewal, effectively reducing the risk of respiratory diseases among chicken flocks.
