About B&S Filtration
B&S Filtration GmbH was founded in Weinheim in 1992 and develops and produces air filters with a focus on particulate filters, gas filters (activated carbon) and their combinations as well as HEPA/ULPA filters. In the roughly 11,000 m² particulate and carbon filter plant, 20 production units with modern pleating systems produce filter media with pleat heights of 9 to 100 mm, with up to five media able to be combined into a single filter build. The HEPA/ULPA production facility, in operation since 2014, produces pleated packs that are fitted into frames made of aluminium, MDF or metal. Customers receive services ranging from design (2D/3D CAD) and prototype and sample construction with in-house toolmaking through to production, testing in the company's own laboratory and customer-specific packaging. Customer sectors include automotive engineering, building services, industry, power generation, cleanroom technology, life science, kitchen filtration and the semiconductor industry. More than 200 employees work at the Weinheim site; all products are manufactured in Germany.

Materials and Processes
Activated carbon (granules 0.25–0.84 mm)
Granules for gas and odour separation in adsorption filters, tested for grain size and residual moisture in the company's own laboratory.
Ion exchanger (granules)
Granules for adsorption applications, tested for residual moisture content.
Particulate filter media (G4–F9)
Media from coarse to fine dust separation, pleatable in heights of 9 to 100 mm.
HEPA/ULPA material (E10–U17)
Special material for suspended matter filters according to EN 1822, tested with a particle scanner and oil mist test.
Aluminium
Frame material for HEPA/ULPA filter elements.
