Hole diameter: 85mm (AutoFlow 80), 105mm (AutoFlow 100), 165mm (AutoFlow 160)
The range
Building refurbishment with replacement double glazing can often lead to condensation problems if there is inadequate ventilation. With central systems, be it central extract using multipoint system or a positive pressure system, it is often now necessary to provide passive ventilators in tight rooms. Introducing Xpelair AutoFlow, a simple and neat passive ventilation unit designed for installation at high level through a wall using a core cutter. Xpelair AutoFlow is self regulating and adjusts the airflow in relation to the outside temperature.A self contained, temperature sensitive thermostatic piston controls the opening of the indoor vent disc. In automatic operation the aperture decreases with declining outdoor temperature and increase with rising outdoor temperature.
The unit comes complete with wall tube and outside weather protected wall grille.
