How Domus Radial Works

  • The chosen MVHR or MEV appliance connects directly to the manifold using Domus rigid ducting
  • The manifold acts as an air distribution hub, each outlet evenly servicing a different room
  • Twin or single semi-rigid duct runs are securely connected to a plenum positioned in each room, terminating with an air valve or grille
  • Option to integrate Domus rigid ducting into the system

What is different about Domus Radial?

  • NEW slimline manifold (125mm deep) enables easy installation between joists or in tight spaces
  • Compact manifold size also allows for greater location flexibility
  • NEW innovative outlet plenum with optional twin connection for increased air flow and lower energy usage
  • Optional integral flow control device allows the outlet plenum to be connected directly to a stylish architectural grille – no air valve necessary
  • Rapid fixing mechanism enables secure and air-tight connection with no leakages
  • Corrugated construction and the unique formulation of semi-rigid duct resists stress cracking and on-site damage
  • Can integrate with Domus rigid duct systems to create versatile hybrid solutions
  • Fire-stopping and insulation components also available

Tested by the Building Research Establishment (BRE) for inclusion within the Product Characteristics Database, Domus Radial offers performance levels that not only are the equivalent to traditional rigid ducting in smaller builds but also exceed these levels in properties with four or more wet rooms

Product Part Number

Domus MD220 Radial Manifold - RDM-MD220


The Domus RDM-MD220 Radial manifold has a 220x90mm spigot which connects the central mechanical system to the manifold with rigid duct, and a further 9 Ø75mm spigots which allow Radial semi-rigid duct to service the property. This helps keep duct runs as simple as possible which in turn maintains optimum system pressure. Should you not use them all, RDPC75 protective caps can be used to plug inoperative spigots.

Main Features

  • The manifold is a specialised component used as a central distribution system. It distributes the air from a Centralised MEV or Heat Recovery unit instead of adjacent to room entry as in traditional branch system.
  • With inherent insulation and sound attenuation properties, this also helps prevent condensation and limit the escape of heat and noise, reducing the requirement for duct silencers.
  • Suitable for most makes of Radial ducting
  • Option to integrate round and rectangular rigid ducting
  • Offers an improved airflow over traditional MVHR ducting methods

Technical Features

  • 125mm deep for installation between joists or tight spaces; making the location/its positioning very flexible
  • 9 potential duct outputs for input or extract air
  • Combines with Domus 75mm semi-rigid ducting
  • Dimensions: H x W x D – 396mm x 421mm x 125mm
  • Features a 220 x 90mm spigot and 9 x 75mm spigots
