SD 和 SFR 吸滤器，带或不带集成止回阀功能。
抽吸过滤器
GEA suction filters are combined with a stop valve and are primarily connected to the suction side of screw-type compressor units. They protect the compressor medium circulation from soiling. When the compressor unit is switched off, the integrated check valve prevents the compressor from rotating in the reverse direction. They are fitted with a check valve and with a replaceable strainer insert made of rustproof metal mesh. The check valve is attached to the bottom of the suction filter casing with hexagonal nuts and is maintenance-free. The strainer is self-centring and is held in the bottom of the casing. The cold gas refrigerant flows through the strainer from the inside to the outside. As soon as the flow of the medium slows down and comes to a standstill, the check valve closes. This prevents the screw-type compressor from reversing and thus no oil is lost.
