Domus RDM-MD220 9 Way 75mm Radial Manifold Flat Duct Side Entry

Dramatically reducing installation time and cost, the RDM-MD220 manifold is a key component of the Domus Radial Duct system. Neatly connecting duct work in a whole house MEV or MVHR system, it may be used on either the extract or intake channel.

Connecting to the main ventilation unit via a flat duct spigot, the RDM-MD220 offers 9 x 75mm duct ports which channel the air carried by the 75mm ducting via the plenums and radial grilles. At 125mm deep, the unit is extremely compact allowing for installation in even the tightest spaces.

With inherent insulation and sound attenuation properties, it helps prevent condensation and limiting heat loss and noise. This reduces the requirement for duct silencers.

Please see the installation guide to the left.


  • Offers an improved airflow over traditional MVHR ducting methods
  • Combines with Silavent / Domus 75mm semi-rigid ducting
  • 125mm deep for installation between joists or tight spaces; making the location/its positioning very flexible
