Checklist for your compressed air motor starting procedure:
1. Air connections
If you connect your air motor, do not connect the secondary inlet connection (reverse port) and the exhaust port.
This allows your motor to start unhindered.
Alternatively, you can use DEPRAG mufflers certified for sound reduction.
2. Connection fittings and operating pressure
Air manifolds, 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 in a performance reduction of 23%.Only with a sustained pressure of 6 bar directly at the inlet port, the air motor can deliver the specified power.
The minimum requirement for the appropriate hose ID is shown for each motor in our product catalog.
Example:
BASIC LINE Air motor with 90 W power Product catalog PDF D 6200):
The minimum flow diameter required for all connection fittings is 13 mm.
3. Air Quality
Maintaining the recommended air quality: dry and particle-free air intake.
Optimum longevity and maximum power is achieved by greasing the motor with resin- and acid-free oils.
One or two drops of oil per cubic meter of compressed air is all that is needed to lubricate your air motor.
DEPRAG BASIC LINE and ADVANCED LINE air motors are also suitable for oil-free operation. However, a resulting power penalty of approximately 15% must be taken into account.
4. Control connection diagrams for controlling our air motors
To control an air motor in one direction, a simple 2/2-way valve is all that is needed.
Air motors that are reversible (i.e. in two directions of rotation) can also be controlled by a simple flow valve, if the motor contains an integrated manual reverse lever (e.g. 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.
If the air motor is used only in one direction of rotation, then operate with a 2/2-way valve:
If the motor is to be used in reverse, then it must be operated with a 5/3-way valve:
The air motor can also be used with two 3/2-way valves if operated in reverse gear:
