Alloy Screen Works

Underdrain systems for sand filters, carbon filters and ion exchange units are available in a wide range of styles and sizes (i.e., in all standard pipe and tube outside diameters).

Units are available as both Header Lateral and Hub Lateral assemblies. Our wedge wire screen laterals and pipe-based laterals can be connected to distributor headers and spider hubs by the following methods:

• Standard NPT threaded connections
• Flanged connections (fabricated or ANSI)
• Welded as one assembly.
