Smoke collection and exhaust
Extraction points, smoke reservoirs or high-level zones, duct routes and discharge locations are coordinated with the building and approved design objective.
Need a smoke extraction system? Start with the smoke zone.
A smoke extraction system must remove smoke from the intended zone without drawing it into other areas or disrupting escape routes. We assess the fire scenario, smoke zone, exhaust path, replacement air, fans, ducts, dampers, controls and required operating sequence before defining the scope.

What makes smoke extraction work?
The exhaust fan is only one part. The smoke zone, extraction points, air path, replacement air and control sequence must work together.
Replacement air path
Air entering the zone must support exhaust without pushing smoke toward escape routes, disturbing the smoke layer or creating uncontrolled pressure conditions.
Controls and interfaces
Detection inputs, fans, dampers, normal HVAC shutdowns, status monitoring, firefighter controls and normal or standby power must follow the required sequence.
From
assessment
to
handover.
Smoke extraction starts with the smoke zone and the required fire-mode objective. We establish the air path first, then coordinate the equipment, controls, testing and records around it.
01
Site assessment
We review the smoke zone, escape routes, current ventilation, available plans, possible exhaust routes and replacement-air paths.
02
Design & planning
We coordinate extraction points, exhaust volume, replacement air, fans, ducts, dampers, discharge, controls, power and system interfaces.
03
Review quotation
We discuss the proposed scope, inclusions, commercial terms and questions before approval.
04
Supply & installation
Exhaust fans, ducts, dampers, controls, wiring and interfaces follow the agreed project scope.
05
Testing & commissioning
The installed system is tested and commissioned against the approved project scope and operating sequence.
06
Service + BFP follow-up
We remain available for maintenance, project records and BFP-related follow-up within our scope.
Smoke extraction installed?
Keep the airflow ready.
We inspect and test the exhaust fans, ducts, dampers, controls, power and connected system interfaces against the documented operating sequence and design criteria within our scope.
- 01
Inspect exhaust fans, belts or drives, ducts, dampers, controls, status signals, discharge points and visible system condition.
- 02
Run the agreed smoke-extraction mode and confirm the initiating inputs, fan starts, damper positions, shutdowns and monitoring signals.
- 03
Check exhaust airflow, replacement-air operation and pressure effects against the documented project criteria.
- 04
Issue test records, identify deficiencies and coordinate corrective work or BFP-related follow-up within our scope.
FAQSmoke extraction,
Smoke extraction,
made clear.
Straight answers about smoke zones, exhaust, replacement air, controls, testing, maintenance and project information.
It is an engineered fire-mode system that removes smoke from a defined area through planned extraction points, fans, ducts or shafts and a safe discharge route. Its controls and replacement-air path must be coordinated with the building strategy.
No. Everyday exhaust is designed for normal air quality or heat removal. Smoke extraction must meet a defined fire-mode objective, operating sequence and performance criteria under the required power and control conditions.
Air removed by the exhaust system must be replaced through a planned path. Poorly located or uncontrolled incoming air can reduce extraction performance, disturb a smoke layer, affect doors or move smoke toward escape routes.
They may be usable only when the approved design allows it and the equipment, temperature rating, air path, dampers, controls, power and normal HVAC functions are suitable for the required smoke-control mode.
Testing follows the documented sequence and design criteria. It can include initiating the fire mode, confirming fans and dampers, checking status signals and shutdowns, and measuring exhaust and replacement-air performance under the required power conditions.
