DHF Exhaust Fan Series
Direct Type Exhaust Fan without belt
——Widely used in agriculture, animal husbandry and greenhouse
Direct drive type negative pressure fan, no belt drive and don’t
worry about the phenomenon of belt slippage. The fan is directly
mounted on a motor avoiding loss of power generated by the power
transmission.The fan with power, the general air volume of the
direct drive type are larger than the belt type, direct drive
without friction noise.

Exhaust Fan Function
- Adopting the CAD/CAM design with high pressure, big air volume,
lower noise, energy saving, running stable, long life time and so
- With consume less power, smooth running and long time life and so
- With sending wind and exhaust function, it is the best choose of a
new type ventilation and decrease temperature. Rigid tube and
opening water distribution device can make the water uniform
smoothly and not easy blocking;
- The beauty shutter can move by manual operation or auto type in
order to dust-proof and waterproof.
