きる。According to the present invention, since the intake duct, electric box, and cooler duct, which are always required, are unified in width and height and arranged on the left and right so as to be independent on the base, the soundproof cover is provided. Eliminates the need for frames for mounting. For this reason, it is possible to obtain an air-cooled packaged compressor that is lightweight, has low manufacturing costs, and can be easily manufactured.

Since it is arranged on a member composed of a stay and a stay, it is possible to easily perform repairs and inspections by removing the air intake duct and pulling out the dryer to the right when maintenance or failure of the dryer occurs. That is, the simple box-shaped intake duct 6 does not require much time for disassembly. (The cooler duct is connected to a heavy cooler and piping.
A large number of wirings such as a wiring to a main power supply and a motor of a customer and a control wiring are connected to the electric box. )
