Ventilation in industrial settings isn’t just about comfort—it’s about safety, compliance, and keeping your space running efficiently. Whether you’re managing a warehouse, factory, gym, or even an animal shed, good airflow helps improve air quality, control temperature, and meet WHS standards.
When it comes to exhaust fans, you’ve got two main choices: roof-mounted or wall-mounted. So, which one’s better for your building?
Let’s break it down.
Why Ventilation Matters in Industrial Buildings
Industrial environments can get hot, humid, dusty—or all three. On top of that, machinery, chemicals, and people generate a lot of heat and fumes.
That’s where industrial roof exhaust fans and wall-mounted system come in. Both roof and wall-mounted systems help push out stale air and bring in fresh air. And according to Safe Work Australia, effective ventilation is crucial for managing airborne contaminants and keeping workers safe.
But where’s the best place to install your fans—on the roof or the wall?
Industrial Roof Exhaust Fans: Whole-Building Ventilation That Works
Roof exhaust fans are a go-to for many industrial sites—especially larger ones. Why? Because heat rises. Installing a fan at the top of your building takes advantage of that natural airflow, pulling out warm air, humidity, and fumes efficiently.
Why Choose Industrial Roof Exhaust Fans?

- Maximised airflow: Ideal for extracting hot, humid air that builds near the ceiling
- Solar-powered options: Cut down on electricity bills with systems like Solar Whiz
- Smart features: Add thermostats or hygrostats to automate your airflow
- Built tough: Designed for Aussie conditions—some are even bushfire-rated or stainless steel for coastal areas
- Low maintenance & low noise: Set and forget
If your space gets uncomfortably hot or damp—think animal sheds, indoor pools, or factories—an industrial roof exhaust fan is often your best bet.
Wall-Mounted Exhaust Fans: Great for Targeted Ventilation
Wall-mounted fans offer more flexibility and are perfect for targeting specific areas—like machinery rooms, chemical storage zones, or confined workshops.
Why Consider Wall-Mounted Fans?

- Targeted airflow: Direct ventilation right where it’s needed
- Easy to install: Ideal for buildings without roof access
- Compact design: Some can act as intake or exhaust fans, depending on your needs
One thing to note—they usually run on mains power, which means higher ongoing energy costs compared to solar-powered roof systems.
Quick Comparison: Roof vs Wall-Mounted Exhaust Fans
| Feature | Industrial Roof Exhaust Fans | Wall-Mounted Fans |
| Airflow | Whole-building ventilation | Zoned/local ventilation |
| Best For | Warehouses, factories, gyms, sheds | Machinery rooms, small areas |
| Power Options | Solar & hybrid options | Mostly mains-powered |
| Installation | Roof-mounted | Wall cut-out & bracketed |
| Maintenance | Low (solar options) | Moderate (motors, belts) |
| Built for Aussie Climate | Bushfire-safe & corrosion-resistant options | General use |
| WHS Support | Helps remove heat & moisture | Works well when paired with roof fans |
Can You Use Both?
Absolutely. A hybrid setup is often the most effective.
You can use wall-mounted intake fans to pull in fresh air and roof-mounted exhaust fans to expel heat and fumes. This push-pull system boosts airflow, prevents hotspots, and improves air quality across your entire facility.
Take Solar Whiz for example—it’s perfect for pairing with passive vents or wall-mounted fans, creating a balanced system tailored to your space.
So, Which Fan System Is Right for You?
It depends on your setup and goals. Here’s a quick guide:
Choose Industrial Roof Exhaust Fans if you:
- Run a warehouse, animal shed, gym, or indoor pool
- Need to tackle rising heat, humidity, or odours
- Want a solar-powered, energy-saving solution
- Operate in harsh Aussie climates (think bushfire or coastal zones)
Choose Wall-Mounted Fans if you:
- Need to ventilate specific rooms or equipment areas
- Have limited or no access to the roof
- Want to add a supplemental system to your current ventilation

Final Thoughts: Which Fan Setup Delivers the Best Results?
Both fan types have their place. But if you’re aiming for whole-building airflow, lower running costs, and minimal maintenance, industrial roof exhaust fans—especially solar-powered ones—are usually the smarter choice for Australian businesses.
