Afriso fuel oil de-aerator, FloCo-2KM Optimum MC-18

The Afriso oil de-aerator FloCo-2KM for single-line systems with return flow feed in oil-fired systems for continuous de-aeration. Suitable for the following media: fuel oil EL (DIN 51603-1) and diesel fuel (EN 590) as well as bio fuel oil (EN 14213) and bio diesel (EN 14214) with max. 20% FAME. Also suitable for areas liable to flooding. Multiple filtration is recommended for burners with an oil consumption of < 20 l / h, while larger systems should be operated by single filtration. Automatic fuel oil de-aerator in safety version with integrated filter, stop- cock and vacuum pressure gauge. Housing with changeover valve for multiple filtration as well as backflow preventer with integrated pressure relief towards the tank. De-aerator hood with triple float safety system to prevent oil foam from escaping via the de-aerator opening. For venting, the return oil is guided via the float chamber and can then be added directly to the supply or it can be filtered again by switching a valve. In case of multiple filtration, the return oil increases the flow rate so that the filter cup is permanently filled with de-aerated oil. In service mode, the vacuum pressure gauge indicates the pump vacuum. The stop cock can be closed to check the suction capacity of the burner pump. Increased vacuum provides information on the degree of polllution of the filter. The drain unit ensures that replacing the filter is easy and clean: Connect the hose, open the drain valve, loosen the lock nut of the filter cup and drain the oil in a controlled way. When the burner hose needs to be replaced, it is sufficient to open a bypass valve so that the oil is drained from the float chamber via the filter cup and the drain unit. Water-tight up to 10 m water column.
