Upper Stack Diffuser for Vessels with 6" Flange Top – Bottom Hole – 0.2mm Slots (Resin Applications)

A-2727-F6 | DN65 Flange | Suitable for 14"–36" Pressure Vessels

The A-2727-F6 Upper Stack Diffuser is a heavy-duty polypropylene upper distributor designed for pressure vessels fitted with a 6" (DN65) flange opening. Specifically engineered for ion exchange resin applications, this upper stack diffuser provides even water distribution across the media bed while preventing resin migration during service and backwash.

Designed for use in 14" to 36" diameter pressure vessels, the diffuser features a 180mm long diffuser tube with 0.2mm precision slots, making it ideal for standard water softening and deionisation resins. The robust flanged adaptor securely mounts to vessels with a 6" DN65 flange, providing a reliable, leak-free installation for commercial and industrial water treatment systems.

Manufactured from corrosion-resistant polypropylene (PP), the A-2727-F6 is suitable for potable water, process water and industrial filtration systems where durability and long service life are essential.

Technical Specification

Applications

The A-2727-F6 is ideal for:

• Water softeners
• Deionisation systems
• Demineralisation plants
• Nitrate removal systems
• Iron and manganese removal units using ion exchange media
• Commercial and industrial water treatment systems
• Process water treatment

Why Choose a 0.2mm Slotted Upper Diffuser?

The 0.2mm slot size has been specifically selected for standard ion exchange resins, providing the ideal balance between water flow and media retention. The narrow slots prevent resin beads from escaping during service or backwashing while ensuring even hydraulic distribution throughout the vessel, helping maximise system efficiency and media life.
