Axial Exhaust Fan Maintenance: Boost Efficiency & Avoid Costly Downtime
Why Do 43% of Industrial Axial Exhaust Fans Fail Prematurely?
Dust accumulation and bearing wear cause 72% of axial fan breakdowns according to HVAC Tech Journal (2024). In our 2025 factory audit, we found operators often overlook blade alignment – a quick fix that can reduce energy use by 18%.
Hack 1: The 5-Step Cleaning Protocol
- Power off and lockout/tagout
- Remove surface dust with compressed air
- Degrease blades using non-corrosive solution
- Inspect axial exhaust fan housing for cracks
- Re-balance using laser alignment tool
