LE and LT are lubricated compressors; LF are oil-less compressors which deliver oil-free air. LF2 up to LF5, LE2 up to LE7 and LE10 50 Hz are single-stage compressors; LE10 60 Hz, LE15, -20, LF7, -10 and LT are two-stage compressors. LT and LE/LF2 up to -7 and LE10 50 Hz are two-cylinder compressors, LE10 60 Hz, LF10, LE15, -20 are three-cylinder compressors. Note: Take care that three-cylinder compressors rotate in the direction as indicated by the arrow on the fan housing (counter-clockwise seen from fan cowl side). LE/LF are built for effective working pressures up to 10 bar. LT are built for effective working pressures up to 30 bar (LT2 only for 15 and 20 bar).

The Tank-mounted unit comprises: - For LE/LF/LT2 and -3: the Power Pack mounted on a horizontal (Fig. 1.4) or vertical (Fig. 1.6) air receiver (AR) with air outlet valve (AV), pressure gauge (Gp), safety valve (SV), air pressure switch with on/off switches (13) and condensate drain valve (Dm). - For LE/LF/LT5 up to -10, LE15, -20 and LT15, -20 (Fig. 1.5/1.7): 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 (6) includes the motor starter. A separate air pressure switch (13) is provided. A silencing canopy (1-Fig. 1.13) is available as an option. The canopy has a hinged top to allow easy access for maintenance. The Base-mounted unit (Fig. 1.8) is a fully operational unit with air pressure switch and on/off switches mounted on a frame (no air receiver). A silencing hood can be added as an option. LE, LF and LT Trolley units (Figs. 1.15 and 1.16) are mobile compressors. They are equipped with either a directly flanged electric motor (LE/LF/LT ETROL - Fig. 1.15) or a petrol engine (LE/LF/LT PETROL - Fig. 1.16). 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 additionally provided with an FX dryer and DD/PD filters. 1.2 Air flow 1.2.1 LE/LF2 up to -5, LE7 and LE10 50 Hz (Fig. 1.10) Air drawn through air filter (AF) and inlet silencer (1) into cylinders (3) is compressed, then discharged through cooler piping (4) and (6) and check valve (CV) into air receiver (AR). 1.2.2 LE10 60 Hz, LE15, -20, LF7, -10 and LT (Fig. 1.11) Air drawn through air filter (AF) and inlet silencer (1) into LP (low-pressure) cylinder(s) (7) is compressed, then discharged to HP (high-pressure) cylinder (8) via intercooler (10). The air is further compressed and discharged through cooler piping (6) and check valve (CV) into air receiver (AR). 2920 1585 00 - 9 - Instruction book 1MCOMPRESSED AIR (1)GpSVAVDm50980DCVMDRSGDPFC25AR34346FNAF (1) Compressed air Fig. 1.10 Air flow of LE and regulating system of LE/LF/LT2 up to -7 with DOL starter and separate air pressure switch 1COMPRESSED AIR (1)Y1CVSGDPGpSVAVDmMDRFCMAF810FN6107AR1213UVUA911550981D (1) Compressed air Fig. 1.11 Air flow of LT and regulating system of LE5 up to -20, LF5 up to -10, LT5 up to -10 and LT15 up to -20 with Y/D starter and electric cabinet 2920 1585 00 - 10 - [...]... 00 Dimension drawing, LE/LT7, -1 0 and LF5, -7 Tank-mounted with optional silencing hood - 31 - Instruction book 5-2 0 ( 14) (3) (5) (7) (6) 2-3 ( 14) (3) (5) (6) (4) 2-3 5 7-1 0 7-1 0 1 5-2 0 7 10 9820 8006 00/3 55769D See page 35 for the text on this figure Fig 2.18 Dimension drawing, LE/LT/LF with CD dryer 2920 1585 00 - 32 - Instruction book 2-1 0 2-7 (12) (11) ( 14) (3) (8) (4) 2 3 5 9820 2239 71/3 55770D... 00 - 19 - Instruction book (1) ( 14) (3) (15) (4) (4) Base -mounted 5 7 9820 2239 43/1 55753D 10 7 7 10 See page 35 for the text on this figure Fig 2.6 Dimension drawing, LE/LT7 up to -1 0 and LF5, -7 Base-mounted 2920 1585 00 - 20 - Instruction book 10 10 15 - 20 (3) (1) (19) (4) 9820 2239 44 55754D See page 35 for the text on this figure Fig 2.7 Dimension drawing, LE10 60 Hz, LE15, -2 0 and LF10 Base-mounted... 00 - 17 - Instruction book (1) ( 14) (3) (5) (4) 15 20 9821 0468 00/8 55755D 1 5-3 0 2 0-3 0 See page 35 for the text on this figure Fig 2.4 Dimension drawing, LT15, -2 0 and LT1 5-3 0, LT2 0-3 0 Power Pack 2920 1585 00 - 18 - Instruction book (1) ( 14) (3) (15) (4) Basemounted 2 3 5 9820 2239 42/1 55752D 2 3 5 See page 35 for the text on this figure Fig 2.5 Dimension drawing, LE/LT2 up to -5 and LF2 Base-mounted... drawing, Tank-mounted LT15, -2 0 (horizontal 250/475 l receiver) 2920 1585 00 - 29 - Instruction book 2-5 2-3 (9) (9) (3) (5) (2) (6) (8) (4) 2 3 5 2 3 5 2 3 5 2 3 5 9820 2239 24/5 55767D See page 35 for the text on this figure Fig 2.16 Dimension drawing, LE/LT2 up to -5 and LF2, -3 Tank-mounted with optional silencing hood 2920 1585 00 - 30 - Instruction book 7 10 5-7 (9) (9) (3) (5) (6) (8) (2) (4) 7 5...
