Re: poly glycol low temp systems auto air vents.
As Pass and score suggests they all work.
I would also suggest that you include a sensible length of branch pipe from the pipe being vented to allow any microbubbles to accumulate before they enter the AAV.Brian - Newton Abbot, Devon, UK

Re: poly glycol low temp systems auto air vents.
Try and use ones with stainless steel bellows and Viton seals. We have this problem in the solar industry all the time. Caleffi makes a good one as does Spirovent (I believe).
