PHS_MEV Units

cMEV Unit

Centralised Mechanical Extract Ventilation

  • SAP APPROVED
  • LOW ENERGY

dMEV Unit

Decentralised Mechanical Extract Ventilation

  • TUV TESTED
  • LOW POWER CONSUMPTION

Functions

Centralised Mechanical Extract Ventilation (cMEV) is a whole dwelling ventilation system that supplies and extracts air continuously at a low rate.

  • Designed with multiple extract points.
  • To draw moisture laden air out of the wet rooms like kitchen, bathroom and utility.
  • To provide a quieter and more efficient system compared to separate fans.

Design Components

  • Central unit – Mounted in a loft or cupboard.
  • Extract Duct – connected to central unit to extract
    polluted air from wet rooms.

Advantages

  • To remove pollutants such as moisture, CO2, VOC,
  • To maintain good indoor air quality.
  • To create a better living environment.

cMEV units – additional features

  • The standard humidity sensor increases the fan speed to remove excess moisture.
  • Manual boost, Can be wired to a PIR for proximity boosting.
  • Saving energy and reducing noise.

Functions

The decentralised mechanical ventilation unit (dMEV) continuously extracts the stale air from the wet rooms directly to outdoor with the highest acoustic comfort.

  • Designed with single extract point.
  • Ideal for application in bathroom, toilet and small/medium premises.
  • To provide low power consumption.

 

Design Components

  • Aesthetic front flat cover
  • Aerodynamic deflectors – To reduce air turbulence and designed to maximise airflow.
  • Rigid optimised spigot – preventing distortion.
  • Multi speed selection – To meet different ventilation requirements.

 

Advantages

  • To provide aerodynamic properties with low noise and increased efficiency.
  • Designed for continuous running: suitable for intermittent operation too.
  • Ideal solution in case of renovation.
  • To ensure the quality of the indoor air is constantly maintained for the health and well-being of the occupants as well as of the building.
  • Totally recyclable plastic components.

 

dMEV UNIT – VERSIONS

  • Quantum AX – The unit continues to run at the selected trickle speed. Boost speed is manually activated via remote switch or ambient sensor, or via light switch.
  • Quantum AX HT – The unit is equipped with an electronic circuit having a humidity sensor on board (adjustable from 50% to 95% RH) and a timer (adjustable from ± 0’ to 30’).
