Living in Sydney means dealing with humidity, cooking aromas, and seasonal temperature swings — and that makes proper ventilation a must. One of the simplest and most effective ways to improve your home’s air quality is by installing the right exhaust fan.
At Voltex Power Solutions, we’ve helped hundreds of Sydney homeowners choose and install exhaust fans that match their needs and space. In this guide, we’ll break down the options, features, and expert tips you need to make the right choice.
Why Exhaust Fans Matter
Exhaust fans do more than just clear out steam or odours. They help:
- Control moisture and prevent mould
- Improve indoor air quality
- Reduce humidity-related damage
- Ventilate spaces with little or no natural airflow

- Quiet operation for comfort
- Matches most interior aesthetics
Installation Needs:
- Requires access to roof cavity

2. Wall-Mounted Exhaust Fans

Choosing the Right Size
Exhaust fan performance depends on proper sizing. Use these ventilation rate guidelines:
- Bathrooms: 25m³/hour per m² of room area
- Kitchens: 40m³/hour per m²
- Laundries: 20m³/hour per m²
Adjust if your home has:
- High ceilings (add 10% airflow per extra metre)
- Little to no natural ventilation
- High humidity or moisture-producing appliances
- Long ducting runs or sharp bends
- Coastal exposure (common in Sydney areas)
Save Energy While You Ventilate
Modern exhaust fans are more efficient than ever. Look for features like:
- High energy star ratings (4.0+)
- Built-in timers to reduce waste
- Humidity sensors for automated performance
- Variable speed control
- Low-wattage DC motors for quieter, lower-cost operation
