Suited for side mounted, top/bottom mounted vessels, custom spool assemblies can be designed to suit specialty vessels/systems.
Available in multiple configurations
Wedge Wire Screen laterals and pipe-based laterals can be connected to distributor and drain headers by fabricated custom bolt patterns, standard NPT thread, fabricated flanges, ANSI connections or welded as one assembly. Laterals are available in all standard pipe and tube diameters for both header-lateral and hub-lateral assemblies.
For the most demanding applications
The combination of a unique internal support-rod structure and the flexibility in the materials available to be used in fabrication (stainless steel and many other alloys) makes Wedge Wire an easy choice when constructing an under-drain system.
Benefits of our Under-Drains & Ion Exchange Internals include:
Continuous-slot design increases open area for better collection
Highly resistant to clogging
Stronger and more durable than mesh screens
Various fitting types and sizes available
Design flexibility
High-precision slot sizes are available to meet your requirements
Economical designs make them less expensive than other screens
Resistant to extreme pressure and temperature variances as well as corrosion

Header Systems
Various header systems are available to suit your specific vessel diameter, flow rate and media size. Federal Screen can fabricate a new system or replace an existing one. We can also help design your system to maximize optimal distribution throughout your media bed.
Hub Assemblies
Each system is specifically designed for your application and serves both as a collector of down-flow service and a distributor of incoming backwash water.
Pipe-based screen laterals
Designed to evenly distribute flow over the entire screen area, pipe-based screen laterals are typically connected to distributors and under-drain headers by NPT or flanged fittings.
