Introduction

SF 15

, SF 17

and SF 22

are stationary, oil free compressors.

Dependent on the model, the compressors have 3 or 4 electric motor driven compressor

modules, enclosed in a sound insulating canopy. The front door panel houses the Elektronikon

Graphic controller and the emergency stop button. An electric cabinet with the electric

components is installed behind the front panel. The compressors can be delivered with or without

integrated refrigerant air dryer.

SFD 11

, SFD 15

and SFD 22

are stationary, oil free compressors. They have a duplex setup

of the compressor compartment, existing of 1 or 2 active compressor modules and 1 or 2

compressor modules as backup, enclosed in a common sound insulating canopy. The front door

panel of each set of compressor modules houses the Elektronikon Graphic controller and the

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 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.
