Radial ductwork system that simplifies mechanical extract ventilation (MEV) and mechanical ventilation heat recovery (MVHR) installation and meets the demands on modern ventilation systems.

All circular plenum connections are supplied with gaskets as used on Lindab Safe systems, which fulfil the toughest demands for airtightness. This ensures the ducting can be interconnected quickly and easily.

All manifolds and plenum boxes have a Smart Lock function that allows Lindab’s LFPE semi-flexible duct to be attached with a simple push and click, to be quickly removed without the need for tools, with no damage to the flexible duct or the plenum/ manifold.

Features and benefits:

Complies with building regulation guidelines and is SAP Appendix Q listed.
Radial system: The radial principle involves individual ducting tubes from each extraction and supply point to plenum and distribution boxes connected to the mechanical unit. This eliminates cross-contamination and noise transfer.
Semi-rigid ducting: Requires minimum space and can be run in voids without interfering with other services or structural members.
Reduced power use: Lindab semi-rigid duct takes a swept bend form around corners and has a smooth internal surface that reduces pressure drops and power consumption.
Energy-efficient: Supply and extract points feed directly from central distribution boxes, significantly reducing system pressure drops and power loss to maximise fan power efficiency.
Airtightness: Components fulfil the requirements of air tightness class D, Lindab Safe connections on circular plenums have built-in double lipped gaskets and are Eurovent certified.
Easy installation: Push and click Smart Lock enables simple installation without the need for specialist tools. Installation time can be reduced by up to 66% compared to traditional ducting methods (no sealant or tape required). Ducting can also be removed easily if required.
Fire protection: Intumescent fire sleeves and collars offer fire protection, thus avoiding the need to construct fire resistant ducts.
Noise sensitivity: Provides acoustic separation, eliminating crosstalk sound transfer between rooms. Optional silencers are available to further reduce noise levels/ sensitivity. The system includes dampers, silences, valves and grilles.
Enhanced aesthetics: Lindab Airy high-performance air valves offer an improved appearance for harmonised integration with interior design.
Compliance: Complies with building regulation guidelines and is SAP Appendix Q listed, which simplifies a building's energy consumption calculations.
The semi-rigid polyethene (PE) ducting is anti-static and antibacterial, with a corrugated outer surface to reduce pressure drops at corners and has a smooth inner surface to reduce air resistance.
