Central dust extraction for fiberglass production in Harju County
Elister solved the dust extraction problem of a fiberglass manufacturer, where each unit operated with a separate filter unit and failed to ensure a clean working environment. All units were connected to a single GRAM ACF type centralised filter unit with automation and pressure control. The result is a clean working environment and efficient extraction, whereby the system was designed with reserve capacity to add work surfaces and equipment if needed.

Project challenge
Before the upgrade, dust extraction was arranged so that each machine had its own separate filter unit. This solution could not ensure a fully clean working environment. With each new workbench added, the required extraction became increasingly inadequate.
How we built it
We created a centralised system with automation and pressure control within the production unit. All machines were connected to a single high-capacity filter unit, which was designed with a certain reserve so that additional work surfaces and equipment could be added when needed.
- GRAM ACF type centralised filter unit
- Automation and pressure control
- All production equipment connected to a single system
- Reserve for adding work surfaces and equipment in the future
What we achieved
- A clean working environment throughout the production facility
- Efficient and consistent extraction from all machines
- A system designed with sufficient reserve, allowing equipment and work surfaces to be added in the future without rebuilding the dust extraction again
