Automatic air vents for liquid systems Similar to a steam system, a build-up of air and gas in a liquid system will cause problems. Air locks inhibit the filling of the
system or the priming of pumps, and corrosion will lead to maintenance issues. All these problems will affect the performance
of the system and will have negative effects on the production process. Venting this troublesome air essentially helps keep the
system running efficiently, avoiding downtime and maintenance costs.
