Instrument Filter (Particulate Filters)
FITOK filters are constructed from materials such as stainless steel and brass and apply to gas and liquid services. With special configurations, they are effective at removing fine particulate contaminants from piping, making them suitable for high temperature and high pressure environments. FITOK filter offerings include tee-type filters, bypass filters, in-line filters, and high-capacity filters. Filter elements come in multiple types, with nominal pore sizes ranging from 0.5 μm to 450 μm. Depending on medium properties, working conditions, and installation needs, users can choose the most suitable filter to ensure the stable operation of their fluid systems.
Bypass Filters, FB Series
FB Series Bypass Filters can be used for medium sampling and element cleaning. Filter elements are available in multiple types of filtration accuracy and are easy to replace, making them suitable for use in gas and fluid service.
Filtration Definitions
►Sintered element: metal powder (alloys are available) is pressed in a die at sufficient pressure that the powder particles adhere at their contact points.
►Strainer element: the strainer is cup-shaped and includes an inner cup-shaped support structure having staggered perforations extending through the surfaces thereof, an outer cup-shaped strainer structure constructed of wire mesh is closely received over the support structure.
►Element nominal pore size: the element nominal pore size is normally calculated from the pressure required to cause air to bubble from the largest pore in the filter element when submerged in a test liquid.
