Properly Sizing Exhaust Extraction Systems
Engine exhaust should be captured as close to the exhaust outlet as possible. The closer the capture point is to the tailpipe, the less contaminated air enters the work area. The vehicle type, exhaust temperature, required flow rate, hose length, number of workstations, and the desired range of motion are crucial factors in selecting a suitable exhaust extraction system.
Typical Applications
✔ Automotive and commercial vehicle repair shops
✔ Test benches and engine test areas
✔ Fire and rescue stations
✔ Vehicle garages and depots
✔ Production and service areas involving internal combustion engines
Data collection directly at the vehicle
The most effective solution is usually extraction directly at the exhaust. Depending on the workflow, simple hose systems, hose reels, or track systems that follow the vehicle’s path may be suitable. When vehicles change, the connection and capture element must be sufficiently flexible.
Here’s what you should look for when making your selection
✔ Exhaust gas temperature and temperature peaks
✔ Vehicle and engine size
✔ Required hose diameter
✔ Length and routing of the exhaust hose
✔ Number of workstations operated simultaneously
✔ Required flow rate and system pressure drop
Overview of System Components
| Component | Task | Important |
|---|---|---|
| exhaust hose | Connection to the vehicle | Temperature and Diameter |
| hose reel | Provision and Withdrawal | Range and Installation Location |
| exhaust extraction rail | Flexible Positioning | Traffic Flow and Facility Layout |
| fan | Generates flow rate | Operating Point and Pressure Drop |
FAQ
Is the largest possible fan sufficient?
No. The key factor is the appropriate operating point based on the flow rate and pressure drop of the entire system.
When is a hose reel useful?
If the hose is to be used regularly and then stored in a space-saving manner.
When is an exhaust extraction rail a better choice?
For longer travel distances or multiple possible vehicle positions within a facility.
Can any hose be used for high exhaust temperatures?
No. The hose’s maximum operating temperature must be suitable for the actual application.
Consulting on Exhaust Extraction
For a proper design, the vehicle type, exhaust gas temperature, hose run, number of stations, and the desired workflow should be considered together.
