Ultra fine filters
AL/ST 300
The micfil AL/ST 300 0.5 µm is the ideal filter for all types of trucks, construction machinery, generators, and boats.

AL/ST 300 ultra fine filter with a diesel/petrol flow rate of up to 600 l/h
The micfil AL/ST 300 0.5 µm is the ideal filter for all types of trucks, construction machinery, generators, and boats.
With a diesel/petrol flow rate of up to 600l/h and an engine oil volume of max. 100l in bypass installations, it is also suitable for use under extreme conditions.
The micfil Al(Aluminium)/ST(Stainless Steel) 300 oil and fuel filter prevents abrasion in the machine for bearings, sleeves, and all moving oil-lubricated parts in the engine as well as in the diesel area for injection pumps and injectors. The use of our micfil ultra-fine filter prevents deposits in the combustion chamber, stops abrasion(in piston rings, injectors), and thus achieves a much improved and cleaner combustion.
The special features of the filter include a low price and easy maintenance. The installation leads to a much longer life expectancy of your engines and machines.
The filter can be used as a bypass filter for engine oil, in hydraulic, turbine, gear oil as well as for biofuels and bio-oil (see datasheet).
The micfil AL/ST 300 is suitable for both commercial and private use.
