Application

Unlike conventional intermittent operating extract fans, continuously running extract fans like the MORI dMEV II range do not have a high dependency on background ventilators (e.g. trickle vents in windows) to effectively ventilate a dwelling. In more airtight homes, they will generally require less background ventilators than intermittent operating fans and in less airtight homes, they are unlikely to require any at all. The low dependency on background ventilators combined with extremely low noise levels and running costs, and a wide range of controls and duties to suit various applications, has resulted in the MORI dMEV II range of fans becoming the first choice extract fan range for an increasing number of customers throughout the UK and Ireland.

Operation

MORI dMEV II HT

This unit has 3 conventional flow Background/Trickle speed settings to choose from on site. Comfort Boost flow rate is activated by an integral adjustable humidistat. The Comfort Boost flow rate is approximately half way between the pre-set Background and Boost flow rates. Boost flow rate is activated via the integral pull cord or an external switch via a switched live connection inside the fan. The unit has an adjustable Boost run on timer which is only triggered when Boost has been activated for over 60 seconds to prevent unintentional boost run on.

MORI dMEV II T

This unit has 3 Conventional flow Background/Trickle speed settings to choose from on site. Boost flow rate is activated via the integral pull cord or an external switch via a switched live connection inside the fan. The unit has a similar Boost run on timer facility to the MORI dMEV II HT unit.
