Energy saving by converting the rotating drive movement in<br />
a linear movement of the piston<br />
· A purely linear movement of the piston is attained due to<br />
the patented innovative planetary drive<br />
· In this way, considerably less friction forces develop<br />
· Up to 25% energy saving due to less power loss<br />
More efficient <strong>compressed</strong> <strong>air</strong> generation<br />
· Due to the linear movement of the piston a<br />
longer piston stroke is enabled and the dead space in the piston<br />
is reduced to a minimum<br />
· The smaller the dead space, the higher the degree of efficiency<br />
Targeted lubrication of trouble spots<br />
· Due to the patented forced lubrication the trouble spots<br />
are selectively supplied with oil,<br />
thus there is less oil in the <strong>compressed</strong> <strong>air</strong><br />
· Optimum lubrication also at inclined positions<br />
for a long service life<br />
less oil consumption - 1000 hours maintenance interval<br />
· Due to the patented forced lubrication with an oil pump no oil is whirled<br />
up<br />
· Thus a minimum oil consumption is achieved<br />
· Possible maintenance interval of about 1'250 hours without oil change<br />
low vibration running and running smoothness<br />
· Piston and piston rod made from cast iron, yield one<br />
component<br />
· Due to linear movement less friction,<br />
less heat and less vibrations<br />
· Thus sparing the components and longer service life<br />

Higher losses of power<br />
· Forces acting diagonally on the piston and<br />
minimum canting at each piston stroke<br />
· Thus, higher dissipation and more wear on the<br />
cylinder running surfaces and on the piston<br />
Construction-related loss of power due to<br />
· High acceleration and breaking power<br />
· Limited piston length of stroke<br />
· Larger dead space<br />
· Transport of oil to the cylinder<br />
no targeted lubrication<br />
· No targeted lubrication of the compressor<br />
· There is an oil bath in the crank housing pistons<br />
are oiled by means of the drive needle of the<br />
piston rod after submerging in the oil bath<br />
Increased oil consumption<br />
· Oil is distributed on the piston as well as in the<br />
cylinder the by <strong>air</strong> turbulences in the crankcase<br />
· Thus, increased oil consumption and more oil in<br />
the <strong>compressed</strong> <strong>air</strong><br />
Increased occurrence of vibrations<br />
· Due to the drive via the crank shaft there are high<br />
acceleration, braking and friction powers at each<br />
revolution<br />
· This causes more heat and higher vibrations and<br />
a higher load on the components
