Grinding and polishing in the automotive industry
Grammer AG is one of the world’s leading suppliers of driver and passenger seats for commercial vehicles, trucks, buses and trains. In the automotive sector, Grammer supplies well-known car manufacturers and system suppliers to the automotive industry. The original saddlery was founded back in 1880 and has grown to become a global company with 14,000 employees in 19 countries.
For the final processing of glass panels for a German car manufacturer, a dust mixture of fluff, polishing paste and glass is released during the polishing process. Glass dust has carcinogenic properties that can endanger the health of employees in the vicinity. It was therefore important to find a solution that effectively protects against these dusts.
Two separate work booths were set up specifically for robot grinding and equipped with suitable protective measures to minimize employee exposure to the dust.

Requirement:
- 2 sanding cabins with extraction hoods
- Filtering the cabin air using an extraction system
- Reliable protection against carcinogenic dusts
- Compliance with applicable workplace regulations
- Reliable filtering of 3 types of dust: lint, glass, polishing paste
- Longest possible filter service life
- Smooth 3-shift operation
Our extraction solution:
Robot grinding in 2 cabins
The dust is collected by 3 extraction hoods in the two sanding booths and filtered by a deduster. A pre-separator removes coarse particles and sparks before the air is cleaned by two further filter stages.
Special HEPA H14 filters are used for the fine, carcinogenic glass dust. The cleaned air is then fed back into the hall in energy-saving recirculation mode.
Long life filters
48 antistatic bag filters are ideally suited for continuous operation in 3 shifts. A pre-separator renders sparks harmless and protects the filters from damage caused by coarse particles or chips.
The automatic Jet-Pulse filter cleaning maximizes service life.
Fire and explosion protection
The multi-stage fire protection concept includes a special filter coating, wireless sensors and a powder extinguishing system, thus meeting the highest technical standards in accordance with DIN norms.
Glass dust is not only carcinogenic, but also highly flammable and explosive. The use of a dust extractor therefore requires special explosion protection components in accordance with the statutory ATEX directives.
Result:
✓ 1 deduster, 3 types of dust
The dust mixture of carcinogenic glass dust, fluff and sticky polishing paste is separated from the air via various filter stages without clogging the filters.
✓ Long filter service life
The high-quality permanent filters and the measures for filter protection and filter cleaning protect the filters and increase their service life. This reduces operating costs.
✓ Trouble-free operation
The smooth 3-shift operation and long filter service life prevent downtimes and reduce operating costs. Fires and explosions are effectively prevented over several stages.
