It has the advantages of high precision, small wind resistance, low speed of rotation start-up, high reliability and long service life.
Material: airbag: imported thick cloth, nylon, high-strength waterproof.
For example, in case of fire, we can look at the wind direction of the wind bag so as to run against the wind.
. When toxic gas explodes, according to the wind direction, evacuate people in the leaked contaminated area to the upwind direction. The best guide in an emergency!
Wind direction bag has night light type (absorbing sunlight during the day and emitting light at night to facilitate observation at night) and reflective type (reflecting sunlight during the day), so it is widely used in meteorology, chemical industry, environmental protection, agriculture, oil field exploration and other industries.
A common sense: the wind pocket floats along the wind direction, so the wind pocket refers to the direction in which the wind blows, that is, the north wind blows when the wind pocket is guided, so the wind pocket refers to the opposite direction to the wind.
