for single-line systems with return flow in oil-fired systems for continuous venting
suitable for the media heating oil EL (DIN 51603-1) and diesel fuel (EN 590) as well as bio heating oil and biodiesel (EN 14214) with max. 20% FAME
also for use in flood-prone areas
FloCo-Top-2 can be installed in any system
For burners with an oil consumption < 20 l/h, multiple filtering is recommended
For larger systems, the heating oil vent must be set to single filtering
Automatic heating oil vent in safety design with integrated filter
Shut-off valve and vacuum gauge
Housing with changeover valve for multiple filtration and backflow preventer with integrated pressure relief towards the tank
compact vent hood made of transparent plastic
with 2-float safety system to prevent oil foam from escaping through the vent hole
the connection for the ventilation hose is made unobtrusively from the side
the return oil is passed through the float chamber for venting and can be mixed directly into the flow or subjected to a new filtering process by switching a valve
In multiple filtration, the return oil ensures an increased flow velocity
The filter cup is therefore permanently filled with vented oil
During service, the vacuum gauge shows the pump vacuum
With the shut-off valve closed, the suction capacity of the burner pump can be checked
an increased negative pressure provides information about filter contamination
When changing the burner hose regularly, a bypass valve must also be opened
