Frequently Asked Questions
What does an air supply valve do in a commercial kitchen ventilation system?
An air supply valve introduces controlled fresh air into the kitchen to balance extraction airflow. This prevents negative pressure, improves combustion safety for gas appliances, and maintains comfortable working conditions.
What size is the Canopy UK air supply valve?
The standard model is 100mm diameter, suitable for small to medium fresh‑air inlets or multiple distributed supply points.
Is the valve adjustable?
Yes. Air supply valves are manually adjustable, allowing installers to fine‑tune the airflow rate during commissioning to match extraction demand.
Where are air supply valves typically installed?
They are usually fitted into: • Ceilings near cooking lines • Walls adjacent to extraction canopies • Make‑up air plenums • Fresh‑air ducting feeding the kitchen In the Sunset Catering installation, fresh air was supplied as part of the bespoke canopy system.
Do air supply valves help with gas safety?
Yes. Adequate make‑up air is essential for safe combustion on gas appliances. Without it, extraction can starve burners of oxygen, causing incomplete combustion and CO risk.
Are these valves suitable for high‑temperature commercial environments?
Yes. Air supply valves are made from powder‑coated steel or similar durable materials designed for commercial kitchens, where heat, grease, and cleaning chemicals are common.
Can multiple air supply valves be used in one kitchen?
Absolutely. Larger kitchens or high‑demand extraction systems often require multiple valves to distribute fresh air evenly and prevent draughts over cooking equipment.
Do air supply valves filter the incoming air?
No. Standard supply valves do not include filters. If filtered fresh air is required, it must be added upstream in the ducting system.
Are air supply valves compatible with bespoke canopy systems?
Yes. Canopy UK regularly integrates air supply valves into custom extraction canopy builds, including systems like the Sunset Catering installation where balanced airflow was part of the design.
What maintenance do air supply valves require?
Minimal. They should be: • Wiped down during routine cleaning • Checked during annual ventilation servicing • Re‑adjusted if extraction rates change They have no moving parts beyond the adjustable centre plate.
