We added a few pictures in order to explain the principle of a single screw compressor. As you can see there are one main rotor and two gate rotors (view picture 1). The gate rotors are mounted in the opposite direction as to neutralise the forces exercised on the main rotor. When rotor rotation proceeds,the gate rotor teeth-

-move to reduce the volume of the space in the groove, which results in obtaining compressed air (view picture 2). When the rotor further turns until the specified pressure is reached, the compressed air is delivered from the compression chamber into the oil chamber, where separation from oil is performed (view picture 3).

What makes a Mitsui Seiki compressor so special % o, c1 G C/ B8 \. nMitsui Seiki compressors distinguish themselves from other compressors by means of their outstanding performance level at an attractive price. The output in relation to the kW engine power is extremely high compared to other brands in the field. Whereas the sound level is extremely low. We even dare to say that the Mitsui Seiki compressor is the most silent compressor on the market.

The technology behind Mitsui Seiki Thanks to Mitsui's original know-how and advanced technologies Mitsui Seiki succeeded to achieve an extremely low sound level without making use of thick barriers of isolation material. This low sound level is owed to the fact that the Mitsui Seiki Z-screw compressor has only one main rotor, whereas other screw compressors work with two. The advantage of a single screw compressor over a twin screw compressor is a low speed of revolutions, which ensures less noise and wear and tear.
