Optimised fuel oil de-aerator FloCo-TOP-2
For continuous de-aeration and filtration

The new automatic AFRISO FloCo-TOP-2 fuel oil de-aerator was designed for continuous de-aeration and filtration of fuel oil, diesel, biofuel and biodiesel with 0-20 % FAME in oil fired heating systems (single-line systems with return supply).

The AFRISO FloCo-TOP-2 fuel oil de-aerator, whose new version is even more compact and suitable for use even if space is extremely limited. It can be installed in flood risk area it a vent hose is installed. The fuel oil de-aerator also remains operative after a flood.
The FloCo-TOP-2 series fuel oil de-aerator is extremely popular with installers and features a number of technical innovations: The height of the de-aerator hood has been reduced and the connection for the vent hose is now located at the side so that the unit can be used even if space is very limited. The pressure gauge (service indicator) is now rotatable to facilitate readings.

The de-aerator is equipped with a plastic de-aerator hood, a zinc die cast housing and a compact plastic filter cup. The de-aerator hood features a dual float safety system which keeps oil foam from escaping. If a vent hose is installed, the de-aerator is odour-tight (PROOFED BARRIER). The die-cast housing contains a changeover valve for single/multiple filtration, a shut-off valve for closing the suction line (for checking the suction capacity of the burner pump), a backflow preventer with pressure relief in the direction of the tank, a bypass valve (to drain the oil when the burner hose is replaced) and a drain system for clean filter change. The pressure gauge (-0.7/0.9 bar) serves as a service indicator since increasing pollution causes the vacuum to rise; as a result, it is easy to see when the filter needs to be changed.

FloCo-TOP-2 is suitable for a return flow of up to 120 l/h. The following connections are available: tank side G 3/8 female thread and burner side G 3/8 male thread with 60° cone. The fuel oil de-aerator is TÜV tested and complies with EN 12514-2. The unit is available in five versions and, due to the standard screw connections and the click system, fast and easy to install and can be used with any heating system. The outstanding feature is innovative multiple filtration: the fuel oil returning from the burner is fed either directly to the supply or subjected to additional filtration passes by setting a valve. This continuously increases the fuel oil quality - it surpasses the oil purity levels recommended for state-of-the-art heating systems.
