Instruction book

 

 

For LF 2 up to LF 3:

 The compressor block as described above, with flanged-on electric motor (M), check 

valve (CV) and safety valve (SV). 

 

For LF 5 up to LF 10:

 the Compressor Block as described above, with flanged-on electric motor (M) and 

solenoid valve (Y1) 

The 

tank-mounted unit

 comprises: 

 

For LF 2 up to LF 3:

 The Power pack mounted on a horizontal or vertical air receiver (AR) with air outlet 

valve (AV), pressure gauge (Gp), safety valve (SV), air pressure switch with an on/off button (MDR) and 
condensate drain valve (Dm). 

 

For LF 5 up to LF 10:

 The power pack mounted on an air receiver (AR) with air outlet valve (AV), 

pressure gauge (Gp), safety valve (SV), and condensate drain valve (Dm). An electric cubicle (8) includes 
the motor starter. A separate air pressure switch (MDR) is provided. 

 

 

The 

base-mounted unit

 is a fully operational unit with air pressure switch and on/off switches  

mounted on a frame (no air receiver). 

LF 

Trolley units

 are mobile compressors. They are equipped with either a directly flanged electric motor or a 

petrol engine. The compressors have two outlet connections: 

 

A connection for compressed air at working pressure. 

 

A connection for compressed air at reduced pressure via a pressure regulator. 

 

The 

Full-Feature compressor

 is a tank-mounted compressor provided with a Refrigerant dryer with DD & PD 

filter. They remove moisture from compressed air by cooling the air to near freezing point. This causes water to 
condense. The condensate is automatically drained. The air is warmed up before leaving the dryer. 

2.2 Operation 

 

The compressors are extendible with the following options. For detailed information consult Atlas Copco. 

 

Silencing hood
