Commercial kitchens evolve — equipment is moved, new cooking stations are added, or the layout is reconfigured entirely. Whenever cooking equipment changes, the ventilation system needs to change with it. Poorly adapted ductwork leads to poor grease capture, compliance failures, and increased fire risk. ConAir handles ductwork modifications of all scales.
Extensions and reroutes — extending or rerouting existing ductwork to accommodate new or relocated cooking equipment.
Additional canopy connections — connecting new canopies or cooking stations into an existing extract system.
Duct resizing — where a change in cooking equipment affects required airflow, we resize the ductwork to maintain performance.
Access improvement — identifying and rectifying access shortfalls to meet TR19 requirements following an alteration.
Removal of redundant ductwork — safely decommissioning and removing extract ductwork no longer in use.
Kitchen refurbishment support — working alongside your kitchen fit-out contractor to deliver the ventilation element of a refurbishment project.
Filter Supply
Commercial kitchen canopy filters are the first line of defence against grease entering the extract ductwork. Most canopy filters are durable stainless steel or aluminium and last for years — but if a filter is damaged, lost, or the wrong size for your canopy, ConAir can source and supply a replacement.
Baffle filters — the most common commercial kitchen filter type, made from stainless steel or aluminium, with a labyrinth design for high grease capture efficiency.
Cassette filters — typically used in higher-capacity commercial kitchens and fast food operations where maximum grease capture is required.
Mesh filters — used in lower-duty applications or as secondary filters in some canopy designs.
Filter supply — We can supply any size and type of filter.
Paired with cleaning visits — filters can be supplied and fitted as part of a scheduled TR19 cleaning visit, or on their own whenever a replacement is needed.
Frequently Asked Questions
Do I need to notify anyone when I alter my ductwork?
Alterations that create new penetrations through fire compartment boundaries will likely require fire-rated dampers and may need building regulations sign-off. We advise on the regulatory requirements for your specific alteration before starting work.
Can you work around an operational kitchen?
Yes, where possible. We work with you to plan the alteration to minimise disruption. Some work — particularly ductwork penetrations — may need to be carried out outside operating hours, which we discuss with you upfront.
Does altered ductwork need to be cleaned and inspected?
Yes. Any newly installed or altered ductwork should be inspected to ensure it meets TR19 cleanliness standards. We can combine alteration work with a post-installation inspection.
What is the difference between baffle and mesh filters?
Baffle filters use angled metal baffles that cause grease droplets to separate out of the airstream by inertia — they are more effective and are the standard for commercial kitchens. Mesh filters use a fine screen to physically trap droplets — they offer lower resistance but lower efficiency, typically used in lighter-duty applications.
Can you supply filters for older or unusual canopy sizes?
Yes. We can source filters in non-standard sizes for older or bespoke canopies. Send us the dimensions and we will source the correct filter for your canopy.
