Ultimate Air Assist Wiring For RuiDa Controllers

Upgrading the Air Assist is one thing I highly recommend for your Co2 Laser.

This Ultimate Air Assist Kit installed in your laser can improve your engraving and cutting results. It will also enable you to control the Air via the Software for each cut/engraving layer.

I Supply these to Australian customers here on my site here – AUS Stock – Ultimate Air Assist Kit | MW Laser

For International orders you can purchase this kit here – https://s.click.aliexpress.com/e/_ACrxd1

If using the standard air pump and exhaust fan, these can be connected to the outlets controlled by the relay installed in diagram below.

If using an Air Compressor, it is best to have this running off of a separate mains outlet not controlled by the air assist relay. And the Exhaust fan can use the air assist relay outlet as shown in the diagram below.

This following diagram shows an example of the wiring configuration of the relay for the rear power outlets.

This video demonstrates how to install this on the Chinese Red & Black Laser, it is the same process for most laser machines using RuiDa controllers. This can also be installed on Trocen Controllers, so check out my other Blog post for information relating specifically to Trocen Controller Air Assist Installation.

Thanks Matt for the walk through video – big help with the install. I note that in a later video you talk about the flow restrictor not stemming the flow enough. It looks like Cloudray are including the incorrect restrictor in their package. The valves are directional and the correct one has an ‘A’ printed on the knob but the supplied has a ‘B’ instead which is the wrong direction. The correct part model is PSL601A and can be purchased on Aliexpress or using another flow restrictor type as you have done as a fix.
