How to Alternate Duty Between Two 240V Single Phase Air Compressors Using Pressure Switches

Hi everybody

i've a feeling this query is beneath this forum in many ways, but important to me none the less.

 

I have a workshop with single ohase 240v supply only.

To enable me to do adequate shotblasting i am trying to run 2 x single phase air compressors, supplying a good constant cfm air supply topping up a number of tanks.

To improve the relaiblility of the compressor motors and pumps, i would like to alternate the 2 compressors duty. They each come with a pressure related switch installed so that cut off when the air tanks are at sufficient pressure, and cut back in to "top up" at a pre determined lower level pressure..

Could i link in to these pressure cut in/out switches to make the compressors alternate the duty between them?

 

Have i explained that project adequately?

 

thanks in adavance
