Yoshitake AO-2 is an air separator designed for cold and hot water applications. Its body is larger than the nominal size, which slows the velocity of water and allows the baffle to effectively separate air from the system. It helps prevent noise from water hammer and protects piping systems from corrosion caused by air.

Features

• Body larger than nominal size slows the velocity of water, and the baffle effectively separates air.
• Prevents noise of water hammer caused by air.
• Prevents corrosion of piping system caused by air.
