Greenwood Low Consumption And Noise CMEV.4E Unit

• Top of the energy class
  The best SAP Appendix Q eligible product with an incredible 0.16w/l/s* performance which will help reduce DER’s in SAP and contribute to achieving Level 3 and above of the Code for Sustainable Homes.
   
• Complete control
  A continuously running ventilation system for the whole house that actively contributes to indoor air quality, controlled via a wired in remote switch to control trickle and boost speeds.
   
• Not seen and not heard
  A completely discreet system, centrally mounted in a cupboard means no more nuisance running noise.
   
• Space saving
  5th extract point can be located at bottom of unit (requires cut out on site) for easier connection to ducting in applications with limited space.
   
• A perfect fit
  Compact design (one of the smallest on the market) makes it ideal for apartments and small properties that usually don’t have the window space for all of the trickle vents required with traditional ‘on and off’ extract fans (System 1).
   
• No fuss installation and commissioning
  One of the fastest units to connect and commission on site. 100% variable motor speed options for trickle and boost speeds adjusted through speed pots located on fan body. (medium speed will be based on mid-point between selected trickle and boost speeds).
   
• From inside to out
  Energy efficient EC motor, 5 extract spigots, clever motor assembly design which can be easily removed once isolated, allowing for cleaning and maintenance if necessary.

* 0.16w/l/s based on kitchen + two wet rooms installed with appropriate ducting as detailed in SAP Appendix Q report.

Control

• Wired in 3 position remote switch (GS1) to controltrickle, medium and boost speeds.
   
• Double pole light switches or GS2 switch to control trickle and one boost speed.

Installation

• The CMEV.4 range of units are supplied with 5 x 125mm ducting spigots for connection of ducts to the unit for installation and 2 x blanking plates to cap off unused spigots.
• One inlet spigot is located under the base of the unit and is supplied blanked off. For installations requiring fifth inlet port, proceed to knockout the spigot blank and connect duct. (See Installation instructions).
• 125mm duct should be used to provide the best performance levels required for compliance with building regulations.
• The CMEV.4 range has been tested with both 125mm and 100mm round ducting.
• Note; Reducing ductwork to 100mm will increase system resistance and affect overall specific fan power ratings.
