What air pressure does the ROTOR(+) require?

Answer : 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.

Note: This has been reviewed for the ROTOR+ and we now recommend 5Mpa particularly for ROTOR+ (ROTOR's produced after July 2021). If you are currently running on 4.5MPa there is no need to make any changes but if you are experiencing any air supply issues we will recommend increasing the pressure setting to 5MPa (72.5 psi). No changes to the compressor are required. 

Note: To identify the difference between ROTOR (pre- July 2021) and ROTOR+ please see this article : What model of ROTOR do I have - ROTOR / ROTOR+?

It is possible to run the ROTOR(+) from a mains air supply as long as it can reach the required pressures above. More details can be found here : What are the recommendations for a mains air supply for the ROTOR?

If the ROTOR is supplied with a compressor this will reach a maximum pressure of approximately 8 Bar - 0.8MPa - 116psi.

The compressor that Singer Instruments supply with ROTOR(+)'s will only recharge when the in-operation pressure drops to 6 Bar. This means that the compressor is not running constantly during operation.
