Keeping your grain in perfect condition isn’t just about turning a fan on – it’s about choosing the right fan for the job. At Evans & Pearce, we’ve seen first-hand how even the tiniest detail can make a massive difference.
Why backward curved fans matter
When it comes to moving air through a dense pile of wheat or barley, not all fans are created equal. You might see forward curved fans out there, but for energy efficiency, precision, and peace of mind, backward curved centrifugal fans are simply unbeatable.
- Cutting through resistance
Grain isn’t empty space – it’s a packed mass of seeds. Forward curved fans can struggle under high static pressure, while backward curved fans slice through it effortlessly. That means consistent airflow, less energy waste, and no surprises.
- Non-overloading power
Backward curved fans adjust naturally to changing grain conditions. Your motor never overworks, your electricity bills stay predictable, and your harvest stays cool. Simple, clever, and stress-free.
- Real-world results: The EVO II
Our EVO II fan pairs a backward curved aluminium impeller with low-energy motor technology. The outcome?
50% lower power usage – the 0.55kW EVO II matches the airflow of a traditional 1.1kW fan.
Smart automation – only runs when outside air is perfect for cooling.
Rapid payback – energy savings typically recover your investment in just three seasons.
- Dust and debris? No problem
Backward curved fans are naturally better at handling dust and particles, keeping the fan balanced, maintenance low, and efficiency high.
The takeaway
Forward curved fans might look like a bargain upfront, but they cost more in energy, performance, and peace of mind. Choosing a purpose-built, backward curved system like the EVO II means less stress, lower bills, and perfectly cooled grain.
