4 - TECHNICAL DATA
4.1 - TECHNICAL CHARACTERISTICS
4.1.1 - MONOBLOC, GOOSENECK, PISTONS, CYLINDERS
The monobloc is made of aluminium alloy; the flange with the roller bearings that support the gooseneck is
kept oil-tight with the monobloc by O-rings.
The gooseneck and the connecting rods run on roller bearings only. The four connecting rods are
fitted on the gooseneck with a single crank angle.
The cylinders are made of cast iron and feature traditional multiple piston rings.
4.1.2 - VALVES
The 1st, 2nd and 3rd stage valves are inserted in the head seats and held in place by a bracketing system.
The 4th stage valves are disassembled by removing the head.
4.1.4 - COOLING PIPES, LUBRICATION
The cooling pipes are made of stainless steel.
Lubrication with low pressure oil pump, delivery distributor and paper oil filter with clogging safety valve.
4.1.5 - FRAME, GUARDS
The compressor is mounted on a welded steel frame that has been painted with epoxy resins. The cooling
fan and the trapezoidal transmission belt are protected by steel guards.
4.1.3 - SAFETY VALVES
The safety valve is pre-adjusted during assembly of the compressor and prevents it being damaged in the
event of a malfunction. The infeed pressure, as a function of the valve, is as follows:
225 Bar - (3200 PSI)
330 Bar - (4700 PSI)
Tampering with the safety valve can cause serious damage and renders the warranty null and
void.
