Introduction
General
SF 2
+
, SF 4
+
and SF 6
+
are stationary, single stage, oil-free compressors, driven by an electric motor.
The compressors are controlled by an Atlas Copco Elektronikon controller. See sections Elektronikon
controller and following for details.
The compressors are enclosed in a sound dampening enclosure and are air cooled.
Available versions:
• The Pack version (P) comprises the motor, the compressor element, the air cooled aftercooler and the
regulation and protection components.
• The Full Feature (FF) version is a Pack version, completed with an integrated refrigerant dryer.
The basic version (referred to as the floor mounted version (FM)) does not include an air receiver.
Available options:
• Air receiver of 30 l (7.93 US gal), 270 l (71.3 US gal) or 500 l (132 US gal). The 30 l receiver
consists of a module with three 10 l (2.64 US gal) receivers. The 30 l receiver option includes an
electronic drain.
• Electronic drain on the air receiver on the receiver mounted version (270 l and 500 l).
• Water separator on the outlet on floor mounted compressors without refrigerant dryer.
• Prefilter mats on the air inlet
• Phase sequence relay on 3–phase units.
• FF version: desiccant dryer (CD): for a dew point down to - 40 °C.
• Elektronikon Graphic controller (controller with graphic display). This option is useful if more than
one compressor is connected to the same air net. See sections General and following for details.
SF Pack
An Elektronikon controller module, fitted in the front panel, controls the compressor.
The electric components are located in the cubicle behind the front panel door.
A check valve (CV) prevents loss of compressed air when the compressor is stopped.
A temperature sensor and a safety valve (SV) protect the compressor element against overheating and too
high pressure respectively.
The compressed air is cooled by an air cooler (Ca).
Single phase units are equipped with a vent valve for easy starting.
