Commercial Extraction Ducting & Airflow

Extraction work starts with the whole system

An extractor fan can be working correctly while the system still performs badly. Duct restrictions, poor routing, grease accumulation, loose connections and damaged sections can all reduce extraction performance.

We inspect the relevant fan, motor, electrical condition, duct route and visible system components before recommending repair or replacement. This avoids treating every weak-extraction problem as a simple fan failure.

Commercial priority: For operational kitchens and business premises, tell us the site type, area and whether the extraction is completely down or simply under-performing when you request service.

Services

Common problems we investigate

• Fan does not start or trips the supply.
• Extraction is weak even though the fan is running.
• Excessive noise, vibration or rattling.
• Motor overheats or repeatedly fails.
• Smoke, heat or steam remains in the room.
• Ducting is damaged, blocked or poorly connected.

Gauteng service coverage

We work across Johannesburg, Sandton, Midrand, Randburg, Roodepoort, Alberton, Boksburg, Edenvale, Kempton Park, Pretoria, Centurion, Soweto, Vereeniging and surrounding Gauteng areas.

If a fan has been replaced but extraction remains weak, the system may be fighting excessive resistance or another airflow limitation. That is one reason our commercial fault finding looks beyond the motor before recommending further replacement work.

When the fan is not the problem

New installations need a practical path from the canopy or extraction point to the discharge location. The route should be planned together with the fan and wider system rather than added as an afterthought. We support ducted extraction projects across Gauteng for commercial and industrial applications.

New commercial duct routes

Where poor performance is linked to the duct system, we inspect accessible sections for disconnected joints, visible damage, restrictive routing and other obvious problems. Commercial kitchen systems can also be affected by grease accumulation and require appropriate cleaning and maintenance in addition to mechanical repairs.

Duct repairs and airflow troubleshooting

The fan creates movement, but the duct path determines how easily that air can travel. Tight bends, long restrictive routes, damaged connections and obstructions can increase resistance and reduce the airflow available at the extraction point.
