At present, there are fans of various specifications and different materials on the market, which are used in the field of animal husbandry, industrial production cooling and ventilation. Heavy hammer fan is one of them. The price of this fan is relatively low. Compared with the push-pull type, the price of a fan of the same specification can be different.200Around Yuan.

The heavy hammer fan is equipped with a swing weight, without power, and the shutter is opened only by the air volume of the fan. This novel mechanism can ensure that the fan has no troubles in continuous operation for many years. Other fans are often equipped with centrifugal rods to open and close the shutters.

Performance characteristics:

　　1.The outer frame adopts a novel automatic processing technology with high precision; the extra thick galvanized layer has strong corrosion resistance

　　2.The hub of the fan is made of high-strength aluminum alloy, the fan blades are twisted and stamped, and the angle of the blade is reasonable, which can reach the upper limit of air flow.

　　3.Strict quality testing procedures: noise testing, vibration testing, concentric performance testing, fan blade speed testing, and machine efficiency testing are strictly in accordance with standards;380 VThree anti-motor performance is very high.

　　4.The heavy hammer fan adopts iron collector and tempered glass collector (customers can choose according to their own needs), and the rear safety net is easy to disassemble.
