CME3 Q Plus (MEV)

Central Mechanical Ventilation Unit (cMEV)

The new CME3 Q Plus is ideal for continuous extract of stale, damp and polluted air to the outside environment.

The CME3 Q Plus is the latest addition to the centralised mechanical extract unit range. The combination of aesthetic smooth lines and a low profile makes it the ideal solution for hidden ceiling installation in flats and apartments.

The unit has a very large duty range over 104 l/s (376 m3/hr) at 200 Pa.
