Discover how industrial roof and wall exhaust fans delivered a customised solution for a fabrication facility battling heat and welding fumes.
One Size Doesn’t Fit All in Industrial Ventilation
Industrial spaces like welding and fabrication facilities face unique ventilation challenges. Intense heat, airborne particulates, and welding fumes make it difficult to maintain a safe and comfortable environment using traditional methods alone.
That’s where Solar Whiz steps in—not with a one-size-fits-all system, but with flexible, solar-powered exhaust fans that can be installed on roofs or walls, depending on what your space actually needs.
In this case study, we explore how LHM Fabrication & Fencing used this flexibility to great effect—selecting two industrial roof exhaust fans and two industrial wall exhaust fans to target specific problem areas in their facility. The result? A safer, cooler, and cleaner workspace.
The Challenge: Heat & Fumes in a Welding Workshop
LHM Fabrication, a busy fencing and metalwork company, was experiencing excessive heat buildup and stagnant welding fumes. These conditions weren’t just uncomfortable—they posed safety concerns and impacted productivity on the floor.
With large workshop spaces and concentrated welding areas, LHM needed a solution that could tackle:
- Rising hot air trapped under the ceiling
- Welding fumes lingering at worker height
- Overall air circulation to prevent heat layering and fume stagnation
They approached Solar Whiz to design a setup tailored to these specific airflow challenges.
The Solution: Strategic Roof and Wall Applications
Instead of a standard setup, the Solar Whiz team provided a custom configuration that matched the dynamics of LHM’s workspace, leveraging both industrial roof exhaust fans and industrial wall exhaust fans to maximise effectiveness.
Industrial Roof Exhaust Fans
Placement: Installed at the highest roof points
Purpose:
- Extract hot air rising from machinery and metalwork
- Lower ambient temperature throughout the facility
- Reduce thermal layering (where heat builds up in upper zones)
Why it matters:
Airflow extraction works best when installed at the top of the heat column. These roof-mounted units created an upward draw, continuously pulling hot air out of the space.
Industrial Wall Exhaust Fans
Placement: Installed alongside walls near welding stations.
Purpose:
- Draw in cooler outside air into the facility
- Support airflow circulation by feeding fresh air toward the centre of the workspace
- Help balance air pressure and support effective heat extraction through roof-mounted units
Why it matters:
Rather than extracting air, these wall-mounted units were designed to introduce fresh air from outside. This airflow strategy worked hand-in-hand with the roof exhaust fans, creating a natural push-pull ventilation effect. Cool air comes in from the sides, while hot, stale air exits from the top.
Custom Setup, Clear Results
Here’s how the installation looked in practice:
| Component | Placement | Function |
| 2 Industrial Roof exhaust fans | Highest roof points | Hot, polluted air and general heat extraction |
| 2 Industrial Wall exhaust fans | sidewalls | Improve workstation airflow |
This wasn’t a “dual mounting system”—it was a case of mounting flexibility tailored to the client’s needs.
The Results: Comfortable, Cleaner & Energy-Efficient
“The heat and fume issues we had have been appropriately addressed, and the work environment is far more comfortable and safe.”
— LHM Team
Following the installation, LHM was extremely pleased:
✅ Noticeable reduction in internal temperatures
✅ Clearer air quality around welding bays
✅ Less dependence on mechanical cooling
✅ Improved overall worker comfort and safety
As noted by YourHome.gov.au:
“Effective ventilation improves air quality, reduces overheating and decreases the need for mechanical cooling.”
This solution did exactly that.
Supporting Sustainable Industrial Goals
Solar Whiz helps businesses take real steps toward sustainability:
- Powered by solar energy—reduced grid reliance
- Hybrid-ready for consistent performance even in low-sunlight conditions
- Minimal maintenance with long-lasting build quality
It’s not just a ventilation system—it’s a tool for achieving green building goals in commercial and industrial settings.
A Smart Ventilation Strategy for Industrial Facilities
The LHM case shows that when wall and roof industrial exhaust fans are strategically combined, the outcome is a safer, more efficient workspace.
Whether you’re dealing with heat buildup, fumes, or poor airflow in specific zones, Solar Whiz offers flexible solutions that adapt to your layout and needs.
