Efficient Rotal technique

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

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