Exhaust is made to be installed with a twist motion through the side of a window.

Sharing few models:

100 mm diameter hose and 30x200 mm output,

63 mm diameter hose and 30x200 mm output,

63 mm diameter hose and 30x120 mm output,

plug - for 100 mm hose to 63 mm hole (made for my temporary use till I get 63 mm hose, maybe will be useful for someone).

Added additional sizes:

75 mm diameter hose and 30x200 mm output (should fit window as 100 mm diameter version does),

150 mm diameter hose and 30x200 mm output - not tested if it fits the window!
