Ventilation hood for air exit above roof, suitable for both industrial and comfort ventilation.
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
Contains internal rain funnel to collect rain and snow; drained out of the hood through a hose.
Our fittings are produced in accordance with DW144, and have a rolled edge for safer handling and improved alignment.

Questions and answers of the customers
-
What is the downpipe length and/or can it be ordered to suite the spec ?
-
A Hello JimmyThank you for your question. The pipe length is 3 meters long. What length do you require? as I can ask the factory if they are able to do your requirements.I await to hear back for youKind RegardsAnita
Is that a seperate long male coupler at the base, or is that an integral part of the cowl?
Are there any fixing points on these?
-
QIs that a seperate long male coupler at the base, or is that an integral part of the cowl? Are there any fixing points on these?answer nowA Hello Jake Thank you for your question. The base of the cowl is integral and fits over the duct and can be fitted by riveting the cowl to the duct.
