Case Study: Achieving One-Third Power Savings in Shot Blasting Equipment with Elektror Radial Blower
Background
In today’s manufacturing landscape, energy efficiency is more than a cost-saving measure—it’s a vital part of sustainable operations. One of our clients, a renowned manufacturer of shot blasting equipment, faced the dual challenge of meeting strict industrial cleaning requirements while managing rising energy costs. Their shot blasting machines require a powerful and consistent airflow to ensure optimal blasting and cleaning results, but their existing fan systems were energy-intensive and increasingly expensive to operate.
Challenge
The client’s main concerns were:
High electricity consumption during intensive operations
Difficulty in maintaining stable, high-pressure airflow for even blasting quality
Space constraints in retrofitting new components onto existing machines
They needed a solution that could deliver high performance, efficiency, and flexibility—without major modifications or extended downtime.
Our Approach
After a detailed assessment, we recommended replacing the traditional axial fans with Elektror HRD series radial blowers. These centrifugal blowers are specifically designed for demanding industrial applications, offering substantial pressure and flow rate advantages over conventional solutions.
Key features of Elektror radial blowers that matched the client’s requirements included:
Superior energy efficiency, thanks to optimized impeller geometry and advanced electric motors
Compact and robust design, making them easy to integrate within the limited space of the shot blasting machines
Low-noise, low-maintenance operation for a quieter, more productive work environment
Optional frequency inverters for precise speed and airflow control
Implementation
Our engineering team supported the client in redesigning the airflow system to maximize the blower’s efficiency within the machine’s layout. Throughout the process, we provided on-site technical guidance and helped the customer calibrate the blower-inverter combination to match their exact operational settings.
The transition was managed during scheduled maintenance times, minimizing disruption to production. Installation was seamless, thanks to the blower’s plug-and-play capability and compatibility with standard industrial power supplies.
Results
As soon as the Elektror radial blowers were operational, the manufacturer recorded significant improvements:
Power consumption was reduced by approximately 33%—equivalent to saving one out of every three kilowatt-hours previously used for air movement.
Enhanced airflow stability led to more uniform shot blasting results, improving product quality and reducing rework.
Quieter operation and reduced heat generation contributed to a safer, more comfortable environment for operators.
Conclusion
By upgrading to Elektror radial blowers, this shot blasting equipment manufacturer not only achieved substantial energy savings and improved process consistency but also set a new benchmark for productivity and sustainability in their field. This case demonstrates how the right air movement solution can directly translate into measurable operational and environmental benefits.
