Home Products Filtering elements For liquids ECOSTEK

Ecostek made of composite material based on borosilicate fibreglass


Filter elements ECOSTEK are designed for removal of particles larger than 0.5 μm in liquids at operating temperature from -20 to + 90°C.

Primarily used for the removal of colloidal impurities, removal of opalescence, clarifying and finishing filtration of liquids in various industries.

Construction and materials

The filter material is a fibrous composite film based on submicron glass fibers of different diameters. The filter material, together with the external and internal drainage layers of thermally bonded polypropylene, is laid in the form of a hollow cylindrical corrugated package between the outer and inner perforated frames of polypropylene.

Elements of height 500, 750 or 1000 mm are obtained by welding 2, 3 or 4 elements with a height of 250 mm through the transition parts. Elements of any height can be manufactured both in a deadlock and in the passageway. The end and transition parts, outer and inner perforated frames of the elements are made of monolithic polypropylene and hermetically welded to the ends of the corrugated package.

The particle retention efficiency is not less than 99.9% with the declared filtration rating and the recommended flow rate.

General Information

High specific surface area of composite filtering material based on ultra and micro fiberglass makes ECOSTEK allows to remove colloidal contaminations of various natures  and almost completely to remove yeast and bacterial cells. ECOSTEK elements guarantee high quality of bioburden reduction and protecting sterilization membranes.

The large surface area and high hydrophilicity of the elements make it possible to use them with minimal pressure drops.

High mechanical strength and thermal stability allow filtration with pressure drops up to 3 atm, and also wash and regenerate with hot water or detergent solutions.
