Insect repelling means for preventing insects from entering from the outside air introduction opening is detachably installed. The repelling means includes ultrasonic and electrical means in addition to drugs.

  According to the first air supply device of the present application, dust and insects can be prevented from entering by the filter mechanism, and even if insect dead bodies and dust accumulate on the filter mechanism due to long-term use, the filter is removed from the cleaning opening. Can be removed and cleaned.

  According to the 2nd air supply apparatus of this application, since the cleaning opening part of a filter mechanism can be opened and cleaned from the inspection opening of the ceiling of an installation place, cleaning is easy.

  According to the third air supply device of the present application, dust and insects that have entered the filter mechanism can be easily cleaned by connecting the electrostatic dust collecting means to the housing of the filter mechanism.

  According to the fourth air supply device of the present application, insects can be prevented from entering from the outside air introduction opening by the repelling means.
