Introduction
SF 8
+
and SF 11
+
are stationary, oil free compressors.
The sound insulating canopy contains 2 electric motor driven compressor modules. The front
door panel houses the Elektronikon Graphic controller and the emergency stop button. An
electric cabinet with the electric components is located behind the front panel.
The compressors are available in 2 canopy versions and can be supplied with or without
integrated refrigerant air dryer. The low canopy version is the most compact one, while the high
canopy version has space for up to 2 extra compressor modules (upgrade kits are available).
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.
