A four-part technical video series covering filter nozzle materials, screen slot widths, nozzle geometries, mounting methods, pressure drop design and tailpipe construction for air scour systems.
Material types, screen slot widths and product colour identification.
Nozzle shapes, configurations and mounting strategies.
How pressure drop affects nozzle performance and system design.
Tailpipe construction for air scour and underdrain applications.
This four-part video series — Filter Nozzles 101, 102, 103 and 104 — provides a structured introduction to the theory and design behind high-performance filter nozzles.
The series starts with material selection and screen slot widths, moves into nozzle geometries and mounting methods, explains pressure drop considerations, and finishes with advanced tailpipe construction techniques for air scour systems.
Whether you are an engineer, system designer, plant operator or filtration specialist, these videos walk through key design trade-offs that can influence durability, efficiency and system performance.
Watch each video in order for a complete introduction, or jump straight to the topic most relevant to your project.
Start with the fundamentals: material types, screen slot widths and colour identification. This video is a strong foundation for understanding why nozzle specification details matter.
Learn how nozzle geometry and mounting methods influence system layout, installation approach and long-term filtration performance.
Understand the role of pressure drop in filter nozzle design and why it must be considered properly for efficient, balanced system operation.
Explore tailpipe construction for air scour applications, including considerations for monolithic and steel plate underdrains.
Filter nozzles are small components with a big impact. Material, slot width, mounting style, pressure drop and tailpipe configuration all affect performance.
Discuss Your Nozzle ProjectMatch the nozzle material to the chemical environment, operating conditions and expected service life.
Slot width must suit the media profile and filtration requirements to prevent media loss and support flow.
Pressure drop and distribution need to be considered as part of the complete filter design.
Tailpipe and underdrain design are especially important where air scour is part of the cleaning process.
