LFx0.7 compact single stage oil-free piston compressor

LFx, a single stage Oil Free reciprocating compressor designed for operation at maximum

pressure of 10 bar (145psi) and capacities from 1.02 up to 2.53 l/s at 50Hz, 2.86 to 5.06 cfm at

60 Hz.

Working Principle:

Filtered air is entered through the inlet valve into both cylinders. The piston is driven forward

through the connection rod attached to the balanced crankshaft. The air is compressed in the

cylinder that leaves through the outlet valve when the required pressure of 10 bar (145 psi) is

reached.

Scope of Supply:

Drive arrangement

The standard drive arrangement is direct drive with electrical motor. However, the compressor

block can also be directly driven by a hydraulic motor, diesel or petrol motor and kit is available

for belt drive arrangement.

Electrical Regulation

The standard electrical regulation occurs by means of pressure switch that starts/stops the

compressor at pre-set pressures. Al units are also supplied with over load relay. In standard

models, the cylinder heads are always de-pressurized if the units is stopped via pressure switch.

On units with Direct on Line (DOL) start this is done through the pneumatic Unloader located

inside the pressure switch box. Units with Y/D start are supplied with an Industrial Unloader

Valve and Solenoid valve to de-pressurized the cylinder heads both stopping and starting the

unit. Starting the compressor without back pressure in combination with special Y/D motor

dramatically reduces start-up current. A cubicle is needed to manage the motor running between

Y and D and to control the Industrial Unloader Valve.
