What are the recommendations for a mains air supply for the ROTOR(+)?

Introduction

It is possible to run the ROTOR(+) from a Mains Air Supply. This may be beneficial for some customers who already have a supply in their lab. As well as the convenience and reduction in initial costs it also reduces the maintenance required when running from a compressor. This article explains the requirements for the ROTOR(+) if using a laboratory mains air supply. A PDF version is attached. 

Pressure Requirements

The ROTOR(+) requires a minimum of 6 Bar - 0.6 MPa - 87 psi.
The ROTOR(+) has its own pressure valve which is set at 4.5 Bar - 0.45 MPa - 65 psi, but the supply pressure must be able to maintain a pressure above this.  

Air Supply Requirements

The Air Supply should meet ISO 8573 standards. The specification is described in the ISO 8573 Compressed Air Quality document. The class required for the ROTOR(+) is 2.6.3. Please see the highlighted notes in the appendix of the PDF document attached for an explanation.
A Membrane Drier is recommended which would enable your air supply to meet the correct specifications. The document of a particular IDG Membrane Drier is also attached to this article.

Note : We recommend that all modifications to your air supply are made by qualified/ approved personnel.  

ROTOR Connection

Singer Instruments are able to supply 2 types of connector which will attach to the ROTOR to take the following tubing.
1. 6mm diameter tubing which is often used for compressors with quick connect fittings but can also be used with the correct fittings on a mains supply.
2. 8.5mm bore pneumatic tubing which requires a hose clip. 

Connections to the mains supply and also to the connector are the responsibility of the customer.

Singer Instruments are able to supply the 6mm tubing but the 8.5mm bore tubing and hose clips are to be supplied by the customer.

Conclusion

We hope that this explanation will assist you in performing the above procedure. If you need further assistance do not hesitate to contact the Technical Support Team at Singer Instruments.
