1 LEADING PARTICULARS

1.1 General description

SF1 up to SF15 are stationary, oil-free compressors driven by an electric motor.

1.1.1 Compressor variants

SF Skid (Fig. 1.2)

The components of the compressor are housed in a bodywork with removable front/top panel. The compressor is mounted on a frame designed to allow easy installation at the required spot.

SF Tank-mounted (Fig. 1.3)

The components of the compressor are housed in a bodywork with removable front/top panel. The compressor is mounted on an air receiver.

SF Twin (Fig. 1.4)

Two compressor modules are mounted on an air receiver. Each module is provided with its own control panel.

SF Multi Pack

The compressors have two up to four compressor modules enclosed in a sound-insulated bodywork. The front door comprises an Elektronikon regulator including the start and stop buttons. An emergency stop button is also provided. An electric cabinet comprising the motor starter is installed behind the front door.

SF Multi Full-Feature (Figs. 1.5 and 1.6)

Full-Feature compressors are Pack compressors additionally provided with an air dryer integrated in the bodywork. The dryer removes moisture from compressed air by cooling the air to near freezing point and automatically draining the condensate. See section 1.7.

1.1.2 Compressor elements (Fig. 1.1)

Each compressor element consists of a fixed scroll-shaped housing and a scroll-shaped rotor. Air enters the compressor element through inlet opening (1). Once the air is drawn in, the orbiting scroll

(4)seals the inlet opening and forces the air into a continuously decreasing space. As scroll (4) keeps orbiting, this process of compression is constantly repeated, resulting in discharging of oil-free compressed air through outlet opening (3).
