Integrated check valve

After switching off, the compressor runs backwards for up to approx. 5 s until the pressure in the oil separator is equalised. If the check valve is defective or dirty, this period is extended. Then the valve must be replaced. Installation position: in the discharge gas outlet below the discharge gas shut-off valve or pipe connection.
