Product description

Parallel/Series Filter System

Filtration Systems Model NS-222-V-PS allows conversion from Parallel Filtration to Series Filtration by the use of control valves on an integrated manifold. This versatile system may be used with any combination of #2 size Strainers, Mesh or Micron-Lined Baskets, high-performance liquid filter bags, or high-loading cartridge filters.

Parallel Filtration

Both housings filter simultaneously, doubling the flow rate capacity of a single vessel. Isolation of an individual housing allows each vessel to operate independently for continuous service during media replacement, so that your filtering process never shuts down.

Series Filtration (Staged)

Liquids pass through each housing in sequence. Variations of both particle size and concentration in a solution can be addressed with greater accuracy and efficiency. With Series Filtration, the following benefits are derived:

• Improved Quality Control– Two filters of the same micron rating can be used back-to-back (redundancy) to ensure filtrate quality by improving capture rates.
• Increased Solids Loading – The First Stage pre-filters larger particles; the Second Stage removes smaller particulate for finer filtration or liquid polishing.
• Reduced Cost – Users can select more economical filter media for the First Stage, reserving high-performance products for the Second Stage to promote cost effectiveness.
