<p>The cross-flow ventilator (1) has its housing (2) divided transversely to the direction of rotation into at least two parts (3, 4), with the fan wheel (5) extending along both housing parts. Each housing part has a vortex forming sector (8, 9). There are inflows (19, 21) and outflows (20, 22) for both parts. The two inflows are in opposite directions, and so are the two outflows.</p> |
