Genuine 5 µm filtration for optimum heating values
The AFRISO FloCo-TOP-2KM Optimum MC-18 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). Multiple filtration is an innovation which feeds the fuel oil returning from the burner directly to the supply or subjects it to additional filtration. This procedure and the use of an Opticlean ultra-fine filter MC-18 (5 µm filtration, 1850 cm² filter surface) results in genuine 5 µm filtration for permanently improved combustion and optimum heating values.

The de-aerator is equipped with a plastic de-aerator hood, a zinc die cast housing and a long plastic filter cup. The de-aerator hood features two separate float chambers. The bottom float chamber contains the operation and vent floats, the upper chamber the safety float and the vent opening. This triple float safety system 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.
A 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-2KM Optimum MC-18 is suitable for a return flow of up to 120 l/h. The following connections are available: tank side G 3/8 female and burner side G 3/8 male with 60° cone (G ¼ female optional). The fuel oil de-aerator is TÜV tested and complies with EN 12514-2. Due to the standard screw connections and the click system, the device is fast and easy to install and can be used with any heating system. The AFRISO filter concept achieves genuine 5 µm filtration and surpasses the oil purity levels recommended for state-of-the-art heating systems.
