The hammer type exhaust fan, is a popular type of the negative pressure exhaust fan. It has the widest range of sizes among all exhaust fans. Negative pressure fan is a kind of fan that uses the principle of air convection and negative pressure ventilation to achieve ventilation and cooling. Fresh air is naturally sucked in from the door or window, and the hot and stuffy air in the room is quickly discharged from the installation position of the fan, which can improve any poor ventilation problems, and the cooling effect can reach 90%-97%. The main difference between hammer type exhaust fan and centrifugal system exhaust fan is the way to control the shutter. The shutter of hammer type, opened by the wind blown out by the operation of the fan, and keep the balance of shutters by the swung hammer inside the fan, so it also be called as Weight Balance Exhaust Fan. When the fan shut down. The hammers will ensure the shutter be closed tightly. The shutter of centrifugal exhaust fan, is opened by the centrifugal push-pull system which connected with the blade. Greatly avoid the situation that the shutters cannot be opened due to failure. And the thickness of shutters of centrifugal fan, is twice as thick as the shutters of the hammer type exhaust fan. Only use its own weight to close the shutters tightly
