HOLLOTEX Centrifugal Filter Units (CFU) from Foseco, Cleveland, are the latest addition to the HOLLOTEX range of running and gating system components.

HOLLOTEX CFU products are filtration devices used exclusively in the production of large iron and steel castings. The device comprises a refractory centrifuge system that separates contaminants from liquid metal and resists chemical erosion and STELEX filters that remove contaminants from liquid metal and reduce turbulence in the gating system.

HOLLOTEX CFU products have been specifically designed to assure consistent filter performance and overcome the limitations of traditional multiple filter holders such as inadequate filter support, unbalanced metal flow, velocity and pressure and double inventory requirements for left and right spin units.

The benefits of applying HOLLOTEX CFU products include a reduction in casting defects, rework and scrap; reduced machining allowances, cleaning and machining costs; castings move through the cleaning room faster reducing work in progress and shortening lead times and increased casting quality and consistency.

Foseco is a manufacturer and provider of proprietary consumable products and solutions to the global foundry industry operating in over 100 countries around the world with headquarters for North America in Cleveland.
