Made from 100% synthetic polypropylene, polyester or monofilament nylon fibres, DORSAN® filter bags only use materials that ensure high, consistent quality and efficiency.

All polypropylene, polyester and nylon materials comply with FDA food contact regulations (Title 21, Part 177.1520). S-ring bags have a galvanized steel ring (stainless steel optional) sewn into the top of the bag. V-ring bags have a plastic closure, sewn in or thermowelded via ultrasound system.

The process of filtering liquids using filter bags works as a depth filter and is highly recommendable for filtering liquids with a large quantity of solid or gelatinous particles.

In a depth filter, the area available for solids retention is not only the surface of the filter element; particles are also captured throughout the porous layers through which the liquid flows. Depth filtration is commonly used in a number of sectors, from the chemical-pharmaceutical industry to food, beverages and cosmetics.

Representing one of the best affordable solutions for many liquid filtration applications, the main advantage of depth filtration is its high particle retention capacity and flow rate.
