Vent Axia Response HTP 12v SELV dMEV 404879

The Vent Axia 404879 Response HTP is a continuous running, SELV 12v dMEV unit specifically designed for use in zones 1 and 2 of domestic bathrooms. Utilising 'constant volume' technology, which compensates for outside air pressure, wind and back draughts, the Response ensures that both building regulations and installation required flow rates are always satisfied.

Using a new high pressure axial, the response develops excellent pressure over longer duct runs whilst maintaining the energy efficiency at low air volumes. It has a innovative patented display showing the calibrated airflow and system pressure.

The trickle speed is selected on install to suit the specific requirements from either 6L/s or 8L/s. The HTP 404879 switches to boost speed of 13L/s automatically when the humidistat  detects moisture in the air during, for example, shower times. It may also be switched manually via the integral pull cord if boost is required when steam is not present. 

The Response is manufactured to Vent Axia's renowned high standards from ABS plastic and is extremely quiet in operation. The fan is driven by a 12v, IPX4 motor and the SELV transformer is supplied with the unit. It may be wall or ceiling mounted and offers a multi-orientation grille that can be rotated  90/180 degrees to suit best ceiling configuration.
