Coronavirus update: we remain open and will continue to dispatch and accept orders; although in light of the new guidance we will be operating with a reduced number of staff. We are also reliant on the positions of our suppliers and couriers so our service may be affected by future changes in their circumstances. We cannot accept walk-in custom at this time. Custom manufactured grilles and louvres are not currently available due to a manufacturer shutdown.
Jet cowls offer an advantage over standard round cowls in that expelled air is directed vertically rather than laterally - as is common with most roof terminations. This decreases the possibility that exhaust fumes present a nuisance to neighbouring buildings. Using a jet cowl often means a vertical duct can be shorter than it would otherwise need to be with a standard cowl.
Rainwater is caught in a dish within the cowl and is fed out through a drainage tube.
Jet cowls are designed to connect directly to spiral duct tube
