SI UNITS, SYMBOLS AND DIMENSIONING
Quick selection
for choosing right ow
If you do not make an estimate of cylinder air consumption by
the methods shown on previous pages, the following speed
selection table provide benchmarks for dimensioning.
N
The table below shows the maximum air ow (in
normal liters per minute [l
n
/min]) a cylinder needs.
This value depends on the cylinder piston diam-
eter and operating speed.
The table is applicable at a pressure of 0.5 MPa and
the rate used is the maximum speed/end speed.
If you know the average speed and want to know the
maximum speed you get a proxy if you multiply the aver-
age speed of 1.4.
v max ≈ v average  1.4
Example:
A cylinder with a bore of 32 mm is moving at max.
300 mm/s. According to the table, the cylinder needs
a ow of 90 normal liters per minute.
Should you choose a suitable lter, regulator,
valve and tubing you can not select these compo-

nents with a ow rate of about 90 normal liters per
minute. If you do, the pressure drop is too large, and
the ow into the cylinder is halved. Any components
before the cylinder is like a long chain, producing
constrictions and losses.
As a general rule you can say that the pressure
drop is max. 0.03 MPa of each component. To get
the right ow to the cylinder, each component must
handle much more in ow. A rough guideline is that
each component shall have four times greater ow
than the cylinder needs.
Since 4  90 is 360, the lter, the regulator and all
the other components should have a ow of about
400 normal liters per minute.
The beginning of chapter 4 contains tables that can also
be useful when dimensioning.
