Centralized grinding dust extraction for multiple grinding workstations

The Project Challenge

With multiple sanding workstations, it is not reasonable to acquire a separate vacuum cleaner for each sander, as their motors require frequent replacement due to the heavy load and energy consumption increases significantly. The goal was to create an efficient centralized system that takes into account that not all operators sand simultaneously.

How We Built It

Elister designed a centralized industrial vacuum solution that collects sanding dust from all workstations into a single central filter unit. The system is based on a GRAM high-vacuum device together with a built-out collection ducting and user-based automation. The automation starts the filter when the first workstation is activated and automatically opens the valves of the respective work zone, ensuring optimal power usage according to the current demand. When the last workstation finishes work, the filter switches off automatically.

What We Achieved

Energy consumption significantly reduced thanks to workstation-based valve control and automatic filter shutdown Sanding dust residue from all workstations accumulates in a single central collection box beneath the device Reduced equipment wear, as the need for frequent replacement of overloaded individual motors is eliminated Optimal power usage according to the workstations active at any given time A smoother and more environmentally friendly work process overall
