Commercial Exhaust Canopy Buying Guide Australia | 2026

Every serious cooking line in Australia needs a canopy over it. Commercial kitchen exhaust canopies remove the heat, steam, grease, fumes and airborne contaminants that cooking equipment throws into the kitchen environment all service long — protecting air quality and keeping kitchen staff safe and comfortable through service. But an exhaust canopy isn't a grab-and-go purchase: the type, the size and the airflow behind it all have to match your cooking equipment and your kitchen layout, and getting it wrong is expensive to fix after the canopy is installed.

This guide covers how to choose a commercial exhaust canopy for your kitchen: the main canopy types (wall, island, condensate and ductless), how to size a hood against your cooking line, what actually moves the air, and how filters and cleaning keep the ventilation system safe and hygienic. It's the buying companion to our commercial kitchen ventilation and AS 1668 guide, which goes deep on the compliance side — here we focus on choosing the right canopy system for your establishment.

Types of commercial exhaust canopies

Commercial kitchens use a handful of exhaust canopy systems, and your kitchen layout usually decides which one you need.

• Wall-mounted canopies. The standard choice: a stainless steel exhaust canopy mounts against the wall directly above a cooking line that backs onto it. Wall canopies capture rising heat and grease efficiently because the wall itself helps contain the plume. Most Australian establishments — cafés, restaurants, takeaways — with equipment along a wall use this format.
• Island canopies. For cooking suites positioned in the middle of the kitchen with staff working both sides. Island hoods are larger — they overhang the equipment on all four sides — and need more extraction because there's no wall helping to contain the rising air.
• Condensate canopies. Designed for steam-heavy, low-grease equipment — commercial dishwashers, combi ovens, steamers and pasta cookers. Instead of grease filters, condensate hoods channel condensed moisture into a drainage point.
• Ductless (filtered) exhaust hoods. Self-contained units that scrub the air through a bank of filters and return it to the room, with no ductwork to the outside. A ductless exhaust canopy suits sites where ducting simply isn't possible — leased premises, basements, heritage buildings — for suitable equipment; always confirm suitability against your equipment and local requirements.
• Bench-top filtered hoods. Compact filtered units that sit over a single countertop appliance — a practical option for a lone fryer or griddle in a small food-service setting.

Sizing a canopy against your cooking line

Canopy sizing is where most buying mistakes happen. The rules of thumb:

• Cover the whole cooking line — plus overhang. The canopy must extend past the cooking equipment beneath it on every open side, so the rising plume of heat and grease is captured rather than escaping around the edges. Island canopies need overhang on all four sides, which is why they run larger than the suite beneath them.
• Match depth as well as width. A deep-bodied cooking suite (say, an oven range with a chargrill in front) needs a deeper hood. Measure the full footprint of the equipment, not just its width.
• Mind the mounting height. The gap between the cooking surface and the canopy edge affects capture. Mount too high and the plume disperses before the hood can catch it; too low and you obstruct the working line. Kitchen designers and installers set this against the manufacturer's specification.
• Plan for what the line might become. If you're likely to add a fryer, pizza oven or a bigger range within the equipment's life, size the canopy for the future line now — swapping a hood later costs far more than the extra stainless steel today.

Stock widths run from compact 900 mm hoods up past 4,000 mm for long cooking lines, most around one metre deep, in high-quality 304-grade stainless steel — chosen for its resistance to corrosion, food safety and cleanability in commercial exhaust work. If your line genuinely doesn't fit a stock size, a canopy manufacturer can supply a custom-built commercial canopy to spec — but most kitchens fit a standard width.

Extraction and airflow — what actually moves the air

The canopy is the visible part of a ventilation system; the exhaust fans, ducting and make-up air do the work. Ensuring proper ventilation is a whole-of-system job, not a single purchase.

• Exhaust fan and duct sizing. The fan and ducting must move enough air for the equipment under the hood — higher-output cooking equipment (chargrills, woks, solid-fuel) produces more effluent and needs higher extraction rates. This is calculated by a mechanical services engineer or experienced installer against AS 1668.
• Make-up air. Air pushed out of the kitchen has to be replaced. Without dedicated make-up air, a strong exhaust fan fights the building — doors whistle, the hood underperforms and the kitchen runs hot. Any serious extraction design includes it.
• Ductless is different. A ductless hood recirculates rather than extracts, so its capacity is set by its filter bank. It trades ducting costs for a stricter equipment match and a more demanding filter-maintenance schedule.

For exhaust-rate maths, duct runs and the standards your certifier will check, see the ventilation compliance guide — it covers how commercial kitchen ventilation systems are engineered under AS 1668.1 and 1668.2 in working detail.

Filters and cleaning — hygiene, airflow and fire risk

Grease filters are the canopy's first line of defence: they trap airborne grease and prevent the buildup of grease inside the ductwork. Keeping them right protects airflow, hygiene and your fire-safety position.

• Baffle filters are the commercial standard — stainless steel panels that force air through direction changes, collecting grease as it goes. They lift out and run through the dishwasher, which makes easy maintenance part of the daily routine.
• Clean on a schedule, not on appearance. Grease-loaded filters choke airflow (the kitchen gets hotter and smokier) and become a fuel source. High-output frying and grilling lines need frequent filter cleaning; lighter lines less often — but put it on the cleaning roster either way.
• Don't forget the duct. Grease accumulates in ductwork over time and is a documented fire risk; periodic professional duct cleaning is part of owning a ducted system. Our commercial kitchen fire safety guide covers how exhaust maintenance fits into a venue's broader fire plan.
• Ductless filter banks work harder than baffle filters alone — they typically combine grease, particulate and carbon stages to protect indoor air quality and control odour, and each stage has its own replacement schedule. Budget for consumable filters as an operating cost.

Compliance in brief — AS 1668 and your certifier

You don't need to be a mechanical engineer to buy a canopy, but you should know the shape of the rules. Australian Standards govern mechanical ventilation in commercial kitchens through AS 1668 (often written AS1668) — when a kitchen exhaust hood is required, how much air it must move for the equipment underneath, and how the system must be built. As a guide, cooking equipment above roughly 8 kW electric (or the gas equivalent) triggers the requirement for mechanical exhaust — which in practice captures nearly every commercial cooking line, and solid-fuel equipment like wood-fired pizza ovens carries requirements of its own.

What that means when buying a compliant setup:

• The canopy is specified around the equipment, not the other way round. Lock in your cooking line first, then size the hood and extraction to it.
• Your certifier or mechanical contractor has the final say on exhaust rates, duct routes and make-up air for a new fit-out. Bring them in before you order, not after.
• Keep compliance documentation. The canopy specification, filter schedule and duct-cleaning records all help you meet compliance obligations at inspection time.

Frequently asked questions

What size exhaust canopy do I need for my commercial kitchen?
The canopy must cover the full footprint of the cooking equipment beneath it and extend past the line on every open side, so the rising plume of heat and grease is captured at the edges. Measure width and depth of the whole cooking line, allow for overhang, and size up if you may add equipment later — stock hoods run from 900 mm to over 4,000 mm wide.

What's the difference between a wall canopy and an island canopy?
A wall-mounted canopy sits above equipment that backs onto a wall, which helps contain the rising air — it's the standard format for most kitchens. An island canopy hangs over a free-standing cooking suite and must overhang all four sides with higher extraction, because there's no wall assisting capture.

Can I use a ductless exhaust hood instead of ducted extraction?
Ductless (filtered) hoods scrub air through grease, particulate and carbon filter stages and return it to the room — practical for leased sites, basements and buildings where ducting isn't possible, with suitable cooking equipment. They demand a strict filter-replacement schedule, and you should confirm suitability for your equipment and local requirements before committing.

What is a condensate canopy and when do I need one?
A condensate canopy is designed for steam-producing, low-grease equipment such as commercial dishwashers, combi ovens and pasta cookers. Instead of grease filters it channels condensed moisture to a drain point — the right choice above a dish or steam corner where a grease-filter hood would be the wrong tool.

How often should commercial kitchen canopy filters be cleaned?
Clean grease filters on a schedule matched to your cooking volume — heavy frying and grilling lines need frequent cleaning, lighter lines less often. Grease-loaded filters restrict airflow and are a fire risk, and periodic professional duct cleaning is part of maintaining a ducted system. Put both on the venue's maintenance roster.
