Commercial Kitchen Ventilation System Canopies

Corhaven’s kitchen ventilation canopies are manufactured from type 304 Austenitic stainless steel. All visible surfaces are brushed grain satin polished and welding is of high penetration, reground and polished to match the original finish.


Kitchen Canopy Sizing and construction complies with industry standard DW/172.

Corhaven kitchen ventilation systems are manufactured to comply with the latest industry standards.  Our systems comprise of extract and make-up air systems to provide a comfortable working environment in the kitchen.

The Corhaven canopy is fabricated from quality 304-grade brushed finished stainless steel.  Because of its all-formed, folded and welded construction our canopies are durable, aesthetically pleasing and easy to clean.

All hoods are installed between 2000mm & 2100mm from the floor to the lower leading front edge.  Depending on ceiling height the hoods are flat bottomed but may slope down towards the rear.

All hoods are fitted with high quality stainless steel baffle filters and grease collection drawers.  Lighting is provided via LED flush fitting heat & vapour proof units.

To size the canopy the length of the cook suite is measured and the appropriate overhangs are added as follows:

  • At the end of equipment range 300mm, except in corners.
  • At the front face of equipment 300mm minimum and up to 600mm over Combination ovens.

On make-up air hoods the air is introduced into the kitchen by means of a integrated insulated plenum mounted inside the front face of the hood which is fitted with either adjustable grilles or a perforated stainless steel panel.

If requested fire suppression systems can be fitted to our hoods.

Duct work

The ductwork connects to the hood to convey the extracted air to atmosphere.  Depending on building constraints either spiral or rectangular duct is normally used and is fabricated and installed to comply with DW/144.  Where extract duct passes through a fire barrier fire rated duct is used.

Inspection doors are fitted to the duct to aid cleaning and maintenance.


We use a number of brands for our installations including Systemair, Helios, Elta and Soler & Palau.  All fans are installed using anti-vibration mounts and flexible duct connections.  Speed controllers are supplied with all our installations.


We install all our own systems and carry out on-site surveys to ensure everything goes as planned during the installation process.
