Air in the product water is very common with AIO system designs. This is caused due to the water running through a large air pocket allowing the water to absorb oxygen. Under pressure this tends to stay in solution. Once the water gets depressurized the air will come out of solution. Very similar to why an RO can have a lot of air after changing the filters. The contact tank design or enlarged loop allow a slight decrease in pressure as the water enters the larger diameter section hopefully allowing excess gasses to come out of solution... this design can help but not always, too many variables to say for sure.
This issue is common with Micornizers, AIO, and even h2o2 injection systems when the injection is set to high.
