WHY DOES REFUELLING CAUSE POLLUTION?

When filling a boat’s fuel tank, degassing occurs through the vent pipe.When the tank is full, fuel follows the same path and therefore spills out through the vent.

For technical reasons, the degassing of free air is essential on a boat.

Therefore, environmental pollution is inevitable.

Circuit with Econab

Fuelling with Econab
When filling the tank, fuel passes through the deck entry.

Air is evacuated from the vent hole and contrary to a standard system, fuel, instead of spilling directly from the vent hole, descends into the fuel tank.

When the fuel tank is full, a blow back is created and the fuel pump automatically cuts out before any spillage occurs.

No spillage : zero pollution

Circuit with Econab

REMPLISSAGE DU RESERVOIR
AVEC Econab
Lors du remplissage du réservoir, le carburant
passe par le corps du nable.
Le dégazage passe par le tuyau de l’évent
et contrairement à un montage standard, le
carburant au lieu d’être rejeté directement par
l’évent, repasse par le remplissage.
Lorsque le réservoir est plein, il se crée une
contre pression.
Le pistolet se déclenche automatiquement
avant le débordement.
Pas de rejet : pollution zéro

Operating procedure whilst navigating

Air evacuates from the lower hose connection.

The circulation of air flows through the cap and subsequently through the upper hose connection which is connected to the vent hole.

The ventilation of the fuel tank is respected.
