Primarily for use in dwellings with six wet rooms or fewer

cme centralised mechanical extract unit


The CME2 Q Plus is ideal for continuous extract of stale, damp and polluted air to the outside environment.

The CME2 Q Plus is the latest addition to the centralised mechanical extract unit range. The combination of aesthetic smooth lines, unique tilted impeller and single level ports provides the ideal solution for hidden ceiling installation in flats and apartments.

The unit has a very large duty range over 400m3/hr at reasonable static pressure, this means the unit will provide System 3 ADF ventilation for dwellings primarily up to 300m2 floor area.

Features & Benefits

  • High energy efficiency levels, via Electronically Commutated (EC motor)
  • Very low power consumption/specific fan power
  • Compact – unit is small and low in profile
  • Easy installation due to innovative sub-assembly and unique packaging design
  • Optional two part installation
  • Performs to high levels through rectangular ports on only one level; does away with need for round to rectangular adaptors, saving cost, reducing joints and installation time
  • Optional adjustable humidity sensor (between 55% & 85% relative humidity) triggers boost speed
  • Ideal for central mechanical ventilation in refurbishment of single floor dwellings where there is only space for rectangular ducting
  • Low unit noise
  • Fully adjustable boost overrun timer 0-30 minutes
  • Can accept either 204mm x 60mm or 110mm x 54mm ducting
  • Unit can be cleaned and serviced without disturbing ducting
  • Original enclosure design with 204mm x 60mm spigots, on one level, ideal for low profile ceiling mounting
  • For use in conjunction with Titon trickle vents
  • Setback setting to reduce ventilation where local regulations allow
  • Available in volt free and switch live inputs
  • Hidden fixings
  • Quick and easy commissioning
  • Demand control ventilation ready
  • Wide duty range
  • Patented and registered design
  • Effective in reducing pollutants in the home and improving Indoor Air Quality (IAQ), therefore reducing the risk of Toxic Home Syndrome.
