Ducting
Ducting forms the backbone of your kitchen ventilation system, directing steam, heat and cooking odours safely away from your cooking stations. Whether you're installing new extraction or replacing worn sections, you'll find saddle pieces, elbows, connectors and straight runs in diameters from 150mm to 450mm.
Our ducting components are designed for commercial kitchens and built to handle continuous use in demanding environments.
Ducting components—saddle flanks and fittings in diameters 150mm to 450mm—route exhaust and fresh air through your kitchen ventilation system. Essential for connecting hoods, makeup air units, and extraction fans to external vents. Diameter matching your extraction equipment and ductwork is the critical specification.
When selecting ducting, match the diameter to your extraction hood and fan capacity—undersized runs reduce airflow efficiency and increase noise, whilst oversized systems waste energy. Measure your existing ductwork or consult your ventilation designer to confirm the correct bore size (typically 150mm to 400mm for standard hoods).
Consider the route your ducting will take: horizontal runs need gentle gradients to prevent condensation pooling, whilst vertical sections benefit from weather-sealed terminations. Saddle pieces and angled connectors help you navigate structural obstacles and building layouts. All components should be removable or cleanable to meet food safety hygiene standards.
- Check diameter compatibility with your extraction hood outlet
- Verify gradients on horizontal runs to avoid water traps
- Confirm fire rating and material thickness for your kitchen classification
- Factor in cleaning access points for grease extraction systems
FREQUENTLY ASKED
Common questions
What diameter ducting do I need for my extraction hood?▾
Match the duct diameter to your hood's outlet. Saddle flanks range from Ø 150mm to Ø 450mm. Undersizing restricts airflow; oversizing wastes energy and space. Check your hood's specifications.
What's a saddle flank used for?▾
A saddle flank connects branching ductwork to a main extraction run at an angle, allowing multiple sources (hood, griddle, fryer) to feed one duct without creating turbulent joints.
Do you stock right and left flanks?▾
The sample range shows right flanks available. Confirm left-flank availability for your diameter before ordering, or contact us for the full range across all orientations.
What's the difference between a saddle flank and a 45° saddle piece?▾
A saddle flank branches at a right angle; a 45° saddle piece branches at 45°. Choose based on your layout constraints and how ductwork needs to route through your kitchen.
Are these galvanised or stainless?▾
