A failing or undersized extractor fan is the most common cause of poor kitchen ventilation. Signs include poor smoke clearance, excessive heat, grease migrating beyond the canopy, or a fan that runs constantly without adequate airflow. ConAir assesses your existing system, sources the right replacement, and commissions it correctly.
System assessment — we evaluate your current airflow requirements, duct resistance, and canopy size before recommending a fan.
Fan selection — we source commercial-grade fans suited to kitchen extract, including high-temperature rated fans for kitchen use.
Supply and installation — we handle the full process from procurement to commissioning, minimising your downtime.
Kitchen extract fans — roof-mounted, wall-mounted, and inline fans for commercial kitchen extract systems.
Commissioning and testing — we confirm airflow performance after installation to ensure the system meets requirements.
Frequently Asked Questions
How do I know if my extractor fan needs replacing?
Common signs include a fan that is noisier than usual (bearing wear), reduced airflow, the fan failing to start or stopping intermittently, excessive heat in the kitchen, or visible damage to the fan housing or impeller. Age is also a factor — commercial fans have a finite service life.
Can you replace a fan without replacing the whole system?
In most cases, yes. We assess whether the existing fan can be replaced with a direct equivalent or an improved unit within the existing installation. If ductwork or canopy is also undersized, we will advise on what additional work is needed.
How long does a fan replacement take?
Most straightforward fan replacements can be completed in half a day. More complex installations, particularly roof-mounted fans requiring work at height, may take a full day. We advise on timing before booking.
