Heavy-hammer fan opening and closing mechanism: Its switching mechanism is realized by means of two unpowered hundred-turn heavy hammers and an automatic device. The louver is windproof, dustproof and rainproof.

Motor: V-belt drive, equipped with high-efficiency and energy-saving motor, passed 3C certification, protection class: IP54, insulation class: F class.

Belt: imported B-type belt, no deformation, long life; maintenance-free during the entire service cycle.

Testing: Strict six quality testing procedures: noise testing, vibration testing, rotational concentricity testing, fan speed testing, air volume testing, and overall machine efficiency testing.

Applications:

For ventilation and ventilation: it is installed outside the window of the workshop. Generally, the downwind vent is selected, and the air is drawn out to extract the odorous gas; it is generally used in chemical plants and other applications.

Use with Wet Pad: Used to cool down the workshop in hot summer, no matter how hot your workshop is, the wet pad-negative pressure fan system can reduce the temperature of your workshop by about 8-10C, and there is a certain humidity.

Scope of application of heavy hammer fan:

A. It is suitable for workshops with high temperature or peculiar smell: such as heat treatment plants, casting plants, plastic plants, aluminum profile plants, shoe factories, leather goods factories, electroplating factories, and various chemical factories.

B. Applicable to labor-intensive enterprises: such as garment factories, various assembly workshops, and Internet cafes. ??C, ventilation and cooling in horticultural greenhouses, and cooling in livestock farms.

D. It is especially suitable for places that require cooling and a certain humidity. Such as cotton spinning mills, wool spinning mills, hemp spinning mills, weaving mills, chemical fiber mills, warp knitting mills, texturing mills, knitting mills, silk mills, socks mills and other textile mills.

For exhaust fans: At present, the performance of general exhaust fans (commonly known as Yanggu fans) is relatively poor, and one exhaust fan cannot blow a few people, but the heavy hammer fan is not, whether it is used on the ground or hung in the air. Generally, 4 units are used in a workshop of 1,000 square meters, which means that the whole house is full of wind.
