Diffuser Unit 710 x 710 x 150mm (110mm Outlet) PVOD05101

Diffuser Unit 710 x 710 x 150mm (110mm Outlet)

The Permavoid Diffuser Unit 710 x 710 x 150mm (110mm Outlet) unit is designed to distribute collected rainwater evenly into sub-base aggregate layers beneath permeable surfaces. This Permavoid Rainwater Diffuser Unit supports SuDS drainage systems by slowing water flow and promoting controlled infiltration within permeable pavement construction. Supplied pre-assembled and compatible with standard 110mm push-fit drainage connections, the unit helps simplify installation across residential, commercial, and public realm projects.

Specifications

Key design features

The Permavoid Diffuser Unit uses a wide 710 x 710mm footprint to distribute water evenly through the surrounding aggregate layer beneath permeable surfaces. The integrated 110mm outlet allows direct connection to standard underground drainage pipework, while the pre-assembled design helps reduce installation time on site.

Benefits

• Supports controlled rainwater infiltration within SuDS systems.
• Helps reduce erosion caused by concentrated water discharge.
• Pre-assembled construction simplifies installation.
• Compatible with standard 110mm underground drainage systems.
• Designed for use within permeable pavement construction.

Applications

This Permavoid Rainwater Diffuser Unit is used within permeable paving systems where collected surface water needs to disperse evenly into the sub-base. Typical applications include permeable car parks, driveways, public realm projects, commercial developments, and infrastructure drainage schemes.
