2. Connection Fittings and Operating Pressure

Air distributors, pneumatic valves, quick couplers and air hoses can often be specified with too small a cross section.
This has a direct influence on the performance of your compressed air motor.
A pressure drop of 1 bar results already into a performance reduction of 23%. Only with a sustained pressure of 6 bar directly to the inlet port can the air motor deliver the specified power.
The minimum requirement for the suitable hose ID is shown for every motor in our product catalog.

Example:
BASIC LINE Air Motor with 90 W power PDF Product Catalog D 6200):
The minimum required flow diameter for all connection fittings is 13 mm.

3. Air Quality

Keeping the recommended air quality: dry, particle free inlet air.

The optimum longevity and maximum power output is achieved by oiling the motor using oils free of resin and acid.
One to two drops of oil per cubic meter of compressed air is all that is required to lubricate your airmotor.

DEPRAG airmotors of the BASIC LINE and ADVANCED LINE are also suitable for oilfree operation. However, a resulting power penalty of approximately 15% should be taken into consideration.

4. Connection Control Diagrams for the Control of our Airmotors

To control an airmotor in one direction a simple 2/2-way valve is all that is needed.
Airmotors that are reversible (i.e. into two turn directions), can also be controlled by a simple flow valve, if the motor contains an integrated, manual reverse lever (for example: POWER LINE high performance motors).
Otherwise, a 5/3-way valve or alternatively two 3/2-way valves are needed, so that the unused inlet can be exhausted.

When using any valves, make sure to pay attention to the minimum required hose ID and that the valve allows for the a sufficient flow rate as shown for each motor in our product catalog.
