Operation

Connect your air consumer to the hose coupling. Plug the compressor into a suitable, earthed socket with residual current protection. Engage the motor protection switch, then switch on with the green "I" button and off with the red "0" button.

The pressure relief valve is set to about 4 bar at the factory. Turn it clockwise to raise the pressure and anticlockwise to lower it. Connected equipment must be rated for at least 6 bar.

The compressor has no zero-voltage release. After a power cut it starts again by itself.


Maintenance

Routine maintenance is limited to the two filter elements. Press the latch on each drawer, pull the drawer out, replace a used or clogged filter and push the drawer back in until it locks.

A diaphragm change should be done by a qualified technician. The diaphragm screws are tightened to at least 6 Nm and secured with threadlocker. The same applies to the screws of the upper valve plates.

  • Ambient temperature: -10 °C to +40 °C in continuous operation, up to +50 °C in short-term operation

How to choose the right rotor stator?

First you need to make sure that the rotor stator will fit your machine. Rotor head design and stator diameter need to match. Next you need to assure that the direction of rotation is the same as your machine. Once you are clear about all of this you can choose the model that matches your required flow rate and maximum grain size. If you are unclear about this, you can talk to our team.

Can I return a product I’ve purchased?

A product can only be returned if it has not been in use. Please refer to our General Terms and Conditions

Can I use the pumps for different machines?

Yes, there are many rotor stator pumps that can be used with various different machines. Just make sure that the rotor stator characteristics such as stator diameter, rotor head design and direction of rotation match your machine.
