emergency stop button. An electric cabinet with the electric components is located behind the
front panel of each module. SFD have no integrated air dryer.
SF
SF is the type designation of the compressor variant without integrated dryer. On SF, the
compressed air of each compressor module flows via an individual check valve to a common air
cooler and leaves the compressor via the air outlet valve.
SF Full Feature (SF FF) compressors are SF compressors provided with a refrigerant air dryer,
integrated in the bodywork. The dryer removes moisture from the compressed air by cooling the
air to near freezing point and automatically draining the condensate.
