Micfil Ultra Fine Filters for Fuel and Oil

AL / ST 100

he micfil Ultra Fine Filter purifies all types of oil and diesel down to 0.5 μm while effectively preventing water from passing through.

The micfil AL 100 is manufactured from high-quality industrial components, with connections and piping based on standard hydraulic parts.

Designed to polish, recondition, and stabilize oils and diesel fuels, it restores them to a crystal-clear, bright condition by efficiently removing water, sludge, and all types of sediment.

Easy to operate and maintain, the AL 100 provides a cost-effective and reliable solution for continuous oil and fuel cleaning.

AL / ST 150
Ultra Fine Filtration – Perfect for Trucks, Heavy Equipment, Generators and Marine Engines

The micfil AL/ST 150 (0.5 µm) is a versatile filtration solution designed for trucks, buses, construction machinery, generators, and marine applications.

With a fuel flow capacity of up to 300 l/h for diesel and petrol and a maximum oil volume of 50 liters in bypass installations, the AL/ST 150 is built to perform reliably even under demanding operating conditions.

Constructed from aluminum and stainless steel, the filter protects engines by preventing wear on bearings, sleeves, and other oil-lubricated components. In fuel systems, it safeguards injection pumps and injectors, while its ultra-fine filtration minimizes deposits in the combustion chamber, reduces piston ring and injector abrasion, and ensures cleaner, more efficient combustion.

Key advantages include affordable cost, simple maintenance, and extended engine service life. The AL/ST 150 can be applied as a bypass filter for engine oil, as well as in hydraulic, turbine, and gearbox systems, and is also compatible with biofuels and bio-oils (refer to datasheet).

Whether for commercial fleets or private vessels, the micfil AL/ST 150 delivers dependable protection and long-term savings.

AL / ST 300
Ultra Fine Filter – Handles Diesel and Petrol Flow Rates up to 600 l/h

The micfil AL/ST 300 (0.5 µm) is a robust ultra fine filter designed for trucks, construction machinery, generators, and marine applications.

With a flow capacity of up to 600 l/h for diesel and petrol and a maximum of 100 liters of engine oil in bypass installations, the AL/ST 300 delivers reliable performance even under demanding operating conditions.

Built from aluminum and stainless steel, this filter protects engines by reducing wear on bearings, sleeves, and all moving oil-lubricated parts. In fuel systems, it safeguards injection pumps and injectors. Its ultra fine filtration also prevents combustion chamber deposits, minimizes abrasion on piston rings and injectors, and ensures cleaner, more efficient combustion.

Key benefits include affordable pricing, easy maintenance, and significantly extended engine life. The AL/ST 300 can be applied as a bypass filter for engine oil, as well as in hydraulic, turbine, and gearbox systems, and is fully compatible with biofuels and bio-oils (see datasheet).

Suitable for both commercial and private applications, the micfil AL/ST 300 is a versatile and cost-effective filtration solution.

AL / ST 600
Ultra Fine Filter – Handles Diesel and Petrol Flow Rates up to 1200 l/h

The micfil AL/ST 600 (0.5 µm) is a powerful ultra fine filter designed for heavy-duty applications such as trucks, construction machinery, generators, and marine engines.

With an impressive flow capacity of up to 1200 l/h for diesel and petrol and a maximum of 200 liters of engine oil in bypass installations, the AL/ST 600 is built to perform reliably even under the toughest operating conditions.

This filter provides effective protection against wear in bearing shells, ball bearings, and all oil-lubricated engine components. In fuel systems, it safeguards injection pumps and nozzles, while its ultra fine filtration prevents deposits in the combustion chamber – resulting in cleaner combustion and greater efficiency.

Key advantages include affordable cost, simple maintenance, and significantly extended engine and machinery life. The AL/ST 600 can also be used in hydraulic and operating systems and is fully compatible with biofuels (see datasheet for details).

Suitable for both commercial fleets and private operators, the micfil AL/ST 600 combines durability with cost efficiency.

Filter Cartridges
Ultra Fine Filter Inserts – Maximum Dirt & Water Absorption, Extended Lifetime

The newly enhanced micfil ultra-fine filter insert, made from a tear-resistant fiber mesh reinforced with interwoven cellulose fibers, achieves a filtration level down to 0.5 μm and removes up to 98% of bacteria (diesel fungus) in a single pass – even at high flow rates.

Its unique construction ensures trouble-free operation without blockages, delivering consistent and reliable performance.

The micfil ultra-fine filter insert offers an exceptionally high dirt-holding capacity, long service life, and low differential pressure. In addition, it effectively removes moisture from oils (hydraulic, engine, turbine, transformer, compressor, and gearbox oils) and eliminates approximately 98% of bacteria from diesel fuels.
