The heavy-hammer fan is equipped with a swinging heavy hammer. It does not require power and only depends on the air volume of the fan to open the shutters. This novel mechanism can ensure that the fan can run for years without failure. Other types of fans are often equipped with centrifugal rods to realize the opening and closing of the shutters.

MAIN STRUCTURE

1. Fan: a self-cleaning stainless steel material made by stamping, no dust, beautiful and durable. The special shape of the blade design ensures large volume, no deformation, not broken; the thickness of 1.2mm stainless steel, surface finish grade: BA level.

2. Weight: using high strength nylon swing open shutter opening and closing device, flexible and stable.

3. Tensioning mechanism: the automatic belt tensioner to ensure efficiency and good performance of the most advanced.

4. Fan bearing adopts imported double-row bearing with special waterproof design, water can't enter. High strength, lower noise, maintenance free and long service life.
5. Motor: motor with domestic famous brand motor and SIEMENS motor can be used. The voltage and frequency can be customized. Motor protection grade IP55, insulation grade: F.

Features

1. Adopting advanced automatic processing workmanship, the frame is of high precision.
2. Extremely thick zinc coating provides extremely strong resistance to corrosion.
3. Casting wheel hub made of high strength aluminium alloy and new type distorted stamping fan blades.
4. Rational blade profile angel enables the largest air flow.
5. High-precision microcomputer auxiliary manufacturing system enables the fan to obtain maximum efficiency.
6. Five strict quality inspection procedures: noise detection, vibration detection, concentric performance detection, fan blader rotating speed detection and overall machine efficiency detection.
7. High-performance 380V three-prevention special motors.
8. Iron-made wind collectors, glass fiber reinforced plastics wind collectors and ABS engineering plastics wind collectors(three kinds).
9. The react protecting net is easy to dismantle.

Scope of application

Various types of livestock farms, agricultural flower greenhouses, industrial plants, such as ventilation, cooling, ventilation.
