CME Q Plus (MEV) - Continuous Mechanical Ventilation

Range of fans providing continuous extract of stale, damp and polluted air to the outside environment.

An MEV or CME (Continuous Mechanical Extract Ventilation) system uses background ventilators, usually trickle ventilators fitted in windows and a centrally located continuously running mechanical extract fan with ducts running from the moisture producing areas or “wet rooms” such as kitchens and bathrooms.

The background ventilators provide the whole building ventilation and the central mechanical extract fan runs continuously to remove odours and excessive humidity. A boost facility provides rapid extraction when necessary to remove higher levels of pollutants.

Features and 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, can be fitted in airing cupboards, cupboards or loft spaces.
• Easy installation due to innovative sub-assembly and exclusive packaging design.
• Optional adjustable humidity sensor (between 55% RH & 85% RH) increases unit’s speed proportionally.
• Low unit noise.
• Fully adjustable boost overrun timer 0–30 minutes.
• Unit can be cleaned and serviced without disturbing ducting.
• For use in conjunction with Titon trickle vents.
• Available in volt free and switch live inputs.
• Quick and easy commissioning.
• Demand control ventilation ready.
• Wide duty range.
• Can be mounted on any plane.

CME2/ 2.1 specific:

• Optional two part installation.
• Performs to high levels through rectangular ports; does away with need for round to rectangular adaptors, saving cost, reducing joints and installation time.
• Duct ports on one level, lessening need for unnecessary bends in ducting, saving cost, reducing joints and installation time.
• Ideal for central mechanical ventilation in refurbishment of single floor dwellings where there is only space for rectangular ducting.
• Can accept either 204 x 60 mm (standard) or 110 x 54 mm ducting (using provided converter).
• Original enclosure design with 204 x 60 mm spigots on one level, ideal for low profile ceiling mounting.
• Hidden fixings.
• Patent applied.

CME 3/ 3.1 specific:

• Can accept either Ø125 and/or Ø100.

Airflow at 100 Pa:

• CME 2: up to 137 L/s (493 m³/h).
• CME 2.1: up to 123 L/s (445 m³/h).
• CME 3: up to 120 L/s (430 m³/h).
• CME 3.1: up to 121 L/s (445 m³/h).
