Boiler Air Eliminator

What is the function of the air scoop automatic air purger on heating systems.

Boiler air eliminator.

Product may vary by store. As pressure decreases air is released from the water. Honeywell s hygrovent is an automatic air vent for hot water and steam systems. Product overview automatically purges unwanted air from the hydronic installation to help improve system efficiency attaches to the boiler or it can be used throughout the system nickel plated brass body construction operating pressure ratings of up to 250 psi note.

While terms air eliminator and air separator are often used interchangeably and some manufacturers prefer one term over the other they are both used to indicate a device which collects and eliminates the air from the water in a heating or cooling system. When air is present in a hydronic heating system it causes faster aging of cast iron components and leads to formation of air gaps. Installed in baseboards radiators convectors and high points in piping systems this nickel plated valve has a quick venting design and positive shut off ball check. Models are available in npt vjr sweat vjs press fit vjp horizontal vjr vjs vjp and vertical vjv configurations.

To function properly the air must be eliminated and these air eliminators are designed to remove trapped air micro bubbles and dirt from heating cooling and domestic water systems. Automatic air removal from hot water heating systems avoids air bound boilers baseboards radiators radiant heat loops. Standard models rated for 150 psig and 270 f and solar ht models to 360 f.

As water temperature increases pressure decreases. In that condition the water will provide excellent heat transfer air is an insulator not a good conductor and virtually eliminate noise air makes noise in a hydronic system.
