Filter tube FITO / FOTI

High Precision Filter Tubes OPTIMA spiral cylinders are produced with diameters up to 1,022 mm and a length of 5,500 mm. OPTIMA precision filters made by high-precision automatic welding machines, on the other hand, cover a range from 23 mm to 305 mm in diameter. All OPTIMA products are distinguished by their exceptionally solid construction and are designed for robust use. The considerable compressive strength of the filter tubes can be further increased by reinforcements such as an internal square spiral. Specially developed profiles can give slot widths of up to 6 µm.
