Design Features

Filter nozzles typically consist of a wedge wire screen attached to a stem or pipe. The design of the wedge wire screen incorporates a series of V-shaped profiles, which are resistant to clogging and are easy to clean.

Here are some of the key features of a wedge wire screen filter nozzle:

  1. Profile Wire: The screen is made of profile wire (also known as wedge wire), which creates non-clogging slots for filtration. This allows for a consistent, reliable flow of fluids.
  2. Support Rods: The profile wires are supported by rods, which provide structural strength to the screen. The arrangement of these rods determines the direction of flow — either outside to inside (flow from the exterior of the screen towards the interior) or inside to outside.
  3. Slot Size: The size of the slots in the screen can be customized to suit different applications. Smaller slots will filter out finer particles but may reduce the flow rate.
  4. Materials: Wedge wire screen filter nozzles are often made of stainless steel due to its excellent corrosion resistance, but they can also be made from other materials depending on the application’s requirements.


Wedge wire screen filter nozzles are used in a wide variety of applications, including:

  • Water and Wastewater Treatment: They are used in sand filters and carbon filters to separate solids from liquids.
  • Power Generation: In power plants, they can be used in condensate polishers and ion exchange systems.
  • Petrochemical Industry: They are used in oil and gas filtration systems to remove impurities.
  • Food and Beverage Industry: They are used in filtering processes to ensure product purity.


Wedge wire screen filter nozzles offer several advantages:

  1. High Strength: They are able to withstand high pressures and loads, making them suitable for demanding applications.
  2. Non-Clogging: The V-shaped profile wire design allows for easy backwashing and reduces the risk of clogging.
  3. High Filtration Accuracy: They provide precise filtration control, which is vital for maintaining product quality in various industries.
  4. Long Service Life: Made of durable materials like stainless steel, these nozzles are resistant to corrosion and wear, ensuring a long service life.

In conclusion, wedge wire screen filter nozzles are an essential component in various industrial sectors due to their high strength, non-clogging design, high filtration accuracy, and long service life.
