Heavy hammer type galvanized sheet fan

Name: heavy hammer type galvanized sheet negative pressure fan (white) product features: negative pressure fan is the latest type of fan, mainly used in negative pressure ventilation and cooling projects

It is called negative pressure fan. Negative pressure ventilation and cooling engineering includes ventilation and cooling,

Ventilation and cooling shall be solved at the same time. Negative pressure fan is also used in positive pressure water curtain environmental protection air conditioning and positive pressure

Air supply, positive pressure blowing and other fields. The negative pressure fan has huge volume, super large air duct and super strong wind, with straight blades

Diameter, large exhaust volume, ultra-low energy consumption, low speed, low noise and other characteristics. The negative pressure fan is empty

The cooling principle of air convection and negative pressure ventilation is a kind of cooling principle from the opposite side of the installation site - the gate or the window

Naturally inhale fresh air, and quickly and forcibly discharge the indoor hot gas out of the room. Any problem with poor ventilation

The cooling and ventilation effect of the machine can reach 90% - 100%.
