Vacuum Filter Systems Developed specifi cally for the demands of blending Rugged. Reliable. Proven. Three words that describe Filtres VernayTM rotary vacuum drum fi lter systems. Ideal if your application demands minimal fl oorspace, a low capital investment, or hooded installation. A simple design, with few moving parts, ensures a long life and maximum operating availability.

Confi guration fl exibility is the key to the Filtres VernayTM family of vacuum drum fi lters. With a choice of discharge styles, drum cells, constructon materials, and hooded and open designs, no one offers you more choices to meet process demands.

Filtres VernayTM introduced some of the earliest vacuum drum fi lters in the 1930s. Since then, we’ve continued to innovate with added value features that make this proven technology even more reliable and effi cient. Key advantages include:

• Available in a wide range of sizes—from 0.1 m2 (1.07 ft2) to 120 m2 (1 291.7 ft2)

• Choice of integral frame tank, or tank supported by an inde-pendent carbon steel frame

• Innovative agitator rake design ensures solids remain in suspension and avoids sediment in the system tank for better materials distribution

• Wide range of choices for drum material to suit process demand – polypropylene, carbon steel (unlined or rubber-lined), stainless steel, as well as other materials

• Internal suction pipes are fl ow-optimized to ensure effi cient performance

• Choice of four discharge styles to meet the needs of a wide range of slurrie – scraper, belt/strings, roll, or an automatic micrometric scraper

• Available for standard Pulp (10% w/w) down to 0.01% w/w for precoat systems

Why Choose Filtres Vernay?With a Filtres VernayTM system, you get the capability to precisely confi gure a solution that meets your process demands. And, you get the strength of experience that comes from selecting a partner who’s been building vacuum drum fi lters for more than eight decades.

Effective discharge is a critical variable in a drum fi lter design. Filtres VernayTM systems are available with a choice of four different discharge styles. This enables a wide range of adaptability to suit the physical characteristics, behavior, and rheology of the cake.
