1.LE/LToil-lubricated aluminum piston compressors
LE oil-lubricated for single-stage compression
The single-stage oil-lubricated reciprocating compressor allows filtered air to enter both cylinders through the inlet valve. The piston is driven forward through the connection rod attached to the balanced crankshaft. Maximum operating pressure is 10 bar (145psi) and capacities range from 3.4 up to 31.7 l/s at 50 Hz, 8.3 to 79.8 cfm at 60 Hz. Air compressed in the cylinders leaves through the outlet valve when the pressure reaches 10 bar (145psi).
LT oil-lubricated for two-stage compression
The LT two-stage oil-lubricated reciprocating compressor allows filtered air to enter only one cylinder. This low pressure cylinder feeds the second (high pressure) cylinder that can operate at a maximum pressure of 15, 20 or 30 bar (218, 290 or 435 psi) and with the following capacities:
• 15 bar (218 psi)
from 3.1 to 11.7 l/s at 50 Hz, 7.6 to 23.1 cfm at 60 Hz.
• 20 bar (290 psi)
from 2.1 to 18.0 l/s at 50 Hz, 5.7 to 44.3 cfm at 60 Hz.
• 30 bar (435 psi)
from 2.5 to 17 l/s at 50 Hz, 6.6 to 41.7 cfm at 60 Hz.
Compression temperature is decreased between the two stages for increased compression efficiency.
