A manifold for a medicament dispenser, where a manifold body defines a chimney with an inlet and an exit for directing airflow from the inlet to the exit, and a chamber with a chamber inlet and chamber exit. The chimney exit and the chamber inlet lie side-by-side each other such that when the open blister pocket of the blister pack is positioned adjacent thereto, the airflow may be directed from the chimney exit to the chamber inlet via the open blister pocket to entrain the medicament powder, enabling transport of powder in the airflow from chamber inlet to chamber outlet. The chimney creates turbulence in the airflow at the open blister pocket. The manifold comprises plural chimney exits, located at an angle relative to each other of from 150&#xb0; to 30&#xb0; such that, in use, plural airflow jets are directed at different and conflicting angles towards the open blister pocket.
