Energy costs typically account for 90-95% of a motor’s total lifetime running costs, far outweighing the purchase price over its working life. An IE5 motor like this one reduces energy losses significantly compared to lower efficiency classes, particularly in continuous or high-hours commercial applications, where the difference typically pays for itself within a few years and continues delivering lower running costs for the rest of the fan’s service life.
Note: actual savings depend on your specific running hours, load, and electricity rate. Get in touch and we can help you work out the numbers for your installation.
Key features:
- Integrated controller with active thermal motor protection
- Backward-curved blades for improved aerodynamics and reduced noise
- IE5 efficiency class — minimises energy losses versus lower-efficiency motors
- IP55 protection rating, suitable for demanding environments
- Moisture and hot climate protection as standard
- Ball bearing with long-life lubrication, minimising maintenance
- Inlet nozzle fitted with volume flow measuring device
- Compliant with ErP 2015 and ErP 2026 requirements (complete fan)
