Having all the benefits and features of the Rectangular Ventmatic Range, the Circular Ventmatic Series (SFJC) also has the advantage of being suitable for high vacuum and pressure applications. Its circular construction is also well suited for hygienic applications making it an extremely popular solution for food and pharmaceutical type applications.

The multivalve cleaning system allows ‘on-line’ cleaning and the 120 and 160mm conical cartridges give excellent performance, even in the most arduous of applications. Available with a wide range of options, they can be tailored to suit all applications.

For applications where a cartridge filter solution is either not suitable or desirable, or where a bag type solution is specifically required, the units can be offered with tubular sock bag-type filter elements.
