Automatic Air Vent FAQs
Automatic Air Vent FAQs
Are Any Automatic Air Vents WRAS Approved?
Altecnic/Caleffi offer a full range of WRAS approved air vents for the UK market.
Are There Commercial Versions Available?
Altecnic/Caleffi offer a size range from ¼” to 1”, and also offer air separation devices from 3/4” to DN150 for commercial applications.
Do Any AAVs Come With Check Valves for Servicing & Maintenance?
Yes, there are several codes in differing sizes which come complete with a service check valve. Upon removal of the AAV, the check valve closes, meaning the system does not have to be drained if the AAV requires attention.
I have a High-Temperature Application. Can I Fit a Standard AAV?
This will depend on exactly how high the temperature is. Our standard AAV range has maximums of 110-120C depending on model. However, we also offer a solar range which can accept a higher 160C and a glycol mix.
Is There a Maximum Pressure Rating?
Is There a Recommended Installation Point?
Yes, as AAVs collect air rather than separate it from in the system, it is best practice to install these at the high point of the system for the best efficiency.
