There are various types of ventilation fan motors and ventilator motors in China. Due to different occasions, ventilator motors must meet different types of requirements. Natural ventilators rely on indoor and outdoor atmospheric pressure (air flow) and temperature to determine the ventilating ventilators. It is characterized by small size, the ventilation effect is affected by the environment, the sound insulation effect is slightly poor, and the fresh air entering the room cannot be dust-removed; energy saving and environmental protection: no power consumption, no new noise source, sustainable ventilation; large air exchange volume, large The area of the air exchange channel is designed, and the ventilation volume can be adjusted at will; the heat insulation performance is good, the shell is made of aluminum alloy material, and the interior is filled with heat insulation materials, which has better heat and sound insulation effects; no maintenance, reasonable structure design, no power Components and all parts are free from corrosion; Noise reduction, noise-reducing structural design and sound-absorbing materials in the air channel can minimize indoor noise; Easy to install, sufficient in installation, structural design, material selection, etc. Considering different usage conditions, high safety and reliability; anti-insect, anti-dust, there are anti-insect and anti-dust nets on the ventilation channels; beautiful, unobtrusive screw heads, non-protruding accessories, and its stepless opening adjustment method Adjust the air intake volume according to the wind pressure.
