The EA122 air vent is a reliable automatic venting device and is suitable for venting air or gas from
heating systems or heat process installations.
For hot water heating systems, radiators, wall- and ceiling-mounted air heaters, air collection vessels,
pipework circuits, boilers and air separators.
Service parts
The sludge and air separator serves to separate sludge and air from the heating system. It is equipped
with a sludge and contamination reduction feature that functions according to the cyclone principle.
This guarantees an effective separation of the particles. There is an optional phosphate cartridge
available to prevent corrosion in aluminium-free heating systems.
