Through-draught

The only through-draught came from the two Dorade ventilators in the heads compartment but by the time the air from them reached us on our bunks it felt superheated.

Periodically, of course, the bag has to be removed and emptied, otherwise it will become choked, and the cleaner's efficiency impaired by lack of a strong through-draught of air.

The wind was whistling around the side of the house and there was a through-draught as the kitchen window was open.
