Compressor unit, design - GF32.22-P-4101-02B
The main part of the AIRmatic compressor unit (A9/1) is the compressor motor (m1). The other parts are the pressure relief valve, overpressure/residual pressure valve (b) and the air drier (c).
The air cleaner (a) is located outside the compressor unit. It is connected to the unit by a hose. The air released when the vehicle is lowered is returned to the air filter via the line (g) where it is then guided back out through the filter.
The compressor unit is mounted to a mounting plate (h).
Model 220
The level control valve unit (Y36/6) is fixed at the top of the same mounting plate as the compressor unit and is connected to the compressor by a pressure line. The valve unit is attached to the AIRmatic pressure sensor (B7).
