Another part that is used in the compressor is the Airend or Air air conditioning unit. Inside the Airend, there are shafts in the form of male and female spiral screws, which are used in oil-injected and oil-free compressors to produce compressed air, and the air pressure produced in the airends is between 7 to 13 bar and their power is from 15 to 250 KW. The components of the airends are two shafts (spiral in two forms, male and female), felt bowl, gearbox, bearing and shell, and it starts working by an electric motor. The compression of air in the air compressor is such that the two existing rotors, i.e. male and female, suck the air in with their rotation, and the air is placed between the grooves of the female and moves forward between the blades of the male rotor between the grooves, causing reduction The space between two grooves and this causes the air to condense. In this part, the air entering into the air-generating unit is controlled by the unloader located on the air-end, and in this case, if we do not need compressed air, the unloader does not allow the passage of compressed air and the air-generating unit is unloaded Airends are in 3 turbo, screw and piston models in compressors. Among the best brands available in Iran, we can mention Rotorcomp (EVO) and Aerzen (VMX).
The countries that are engaged in the production of Irand are:
