This vent will let- when stopping the filter pump - air enter in the solar heating so that it runs empty. The moment the pump starts up, the air escapes via the vent (and not through the nozzle).

A deaerator has the disadvantage that the entire installation including filter pump will run empty. To avoid this, an additional non-return valve must be placed - preferably in the suction of the filter pump).

We recommend the use of a deaerator only for solar heaters that extend 6 meters or higher above the pool water. In these installations, due to the negative pressure of the water column when the filter pump is stationary, the solar heating can be sucked flat.

In the box : vent with 50mm connection.
