The ventilation system prevents overpressure when filling a tank without vapor recovery. Air can escape unhindered via the valve (opening pressure: 8mbar). An aeration dryer is screwed directly onto the ventilation system.
If access to the venting system & adsorber is difficult, our Venting System Out Only can be mounted. In this case, the adsorber is connected via a supply line and can be mounted elsewhere independently of the venting system, making maintenance work easier to handle.
