1. Application

DTF series fans can be applied to fire fighting and exhaust fume for various buildings. They are also used to exhaust fume and ventilation for buildings, civil air defense projects, subways, mines and tunnels.

Features

High efficient, energy conservation, stable operation, low noise, thermostability, and convenient installation. It is 2/3 the size and half the weight of centrifugal fan with the same air volume. The mounting mode can be vertical, horizontal and suspended.

This type of fan is equipped with special motor cooling system: built-in air-cooled motor

Advanced pneumatic blades (forward or backward) reduce noise at 8-10 dB (A), and power 6%
