Product Overview

The T35-11 series axial fans are designed for handling non-corrosive gases free of significant dust, with ambient temperatures not exceeding 60°C. They are widely used in general-purpose applications such as factories, warehouses, offices, and residential buildings.
It is widely used in general factories, warehouses, offices, and residential spaces for ventilation or powerful warm-air cooling.
The T35-11 (T40-11) series axial fans represent a new-generation design, improved upon China's T30-11 model from the 1980s. Compared to the T30-11 fan, they offer distinct advantages.
