Cumulative Settling Filters

PFT basket and strainer filters make up one of the most widely used range of filters used to separate solids from liquids in systems with sensitive machinery. These systems include but are not limited to cooling water for boilers, system return water, condensate and pump protection on intake water. With proven design, each filter comprises an assembly of wedge wire  screen. For finer filtration a perforated screen with woven wire mesh is used.

The filters are inserted in a hollow body (known as a filter housing) in the path of the fluid flow, forcing the fluid to pass through the filtering element. The size of the opening  is chosen based on the type of  medium to be filtered and the size of the impurities.

These types of filters can provide a very high degree of separation with little or no pressure drop across them. They must be cleaned  manually at set intervals to eliminate process interruptions.
