Filtration of Fuels & Biofuels

Biofuel blends create new filtration challenges

Biofuels market has grown rapidly in recent years and an increasing number of industrial fuel users are using blends of biofuels which presents a new set of filtration challenges.

Siga Filtration offers a range of cartridge and bag filtration products for the filtration of fuels and biodiesel blends. Our Stainless Steel filter housings provide excellent chemical compatibility with all types of fuels. We have had great success in filtering B20 blend of biodiesel with our specially designed acuraBag Polyester filter bags and compact ALSI bag filter housings.

FINEPleat GFP filter cartridges were introduced with fine fuel filtration applications in mind. These cartridges come with a glass fibre filtration media and Polyester hardware. FINEPleat GFP cartridges are beta ratio 5000 and provide high efficiency filtration of gasoline, diesel and biodiesel blends. These can be used with our 1FU Series of single cartridge filter housings in Stainless Steel.
