Roof Jet Cowl

Our Jet Cowls are usually manufactured  in galvanised sheet steel but can also be manufactured in stainless steel and in varying dimensions.

Our Jet Cowl is a ventilation hood for air exit above roofs which are suitable for both industrial and residential ventilation installations and is manufactured in accordance with DW144.

Air is ejected in an upwards jet to avoid contaminating the air in the vicinity of the hood.
Ejection is so effective that you can install a fresh air inlet in the immediate vicinity of the hood and contains an internal rain funnel drain for the collection of rain and snow.
