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.
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
REMPLISSAGE DU RESERVOIR
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
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.
Remove the existing deck entry
A connect the vent hole pipe 3 from the tank to the lower hose connection.
B Link the vent hole to yhe upper hose connection4
C Link the pipe 2 to the body of the deck entry
The installation is quick and simple
Econab is now operational

European Directive 94/25/EC on the approximation of the laws, regulations and administrative provisions of the Member States relating to recreational craft stipulates in Article 5.8 of Annex 1 that :
“ Craft shall be constructed so as to prevent the accidental discharge of pollutants (oil, fuel, etc.) overboard”.
ECONAB complies with the requirements of EN ISO 11105 standards as regards the ventilation of petrol engine and/or petrol tank compartments.
