Fine dust is a danger to human health. However, the fine dust is not only caused by exhaust emissions: each braking action releases particles. In future the new brake dust particle filter from MANN+HUMMEL will retain these emissions directly at the source.
MANN+HUMMEL has developed a new solution for all of these applications in the form of the brake dust particle filter. Located close to the brake and therefore the source, the filter retains the particles which are the result of mechanical abrasion on the brake. The filter consists of a robust housing which is positioned directly in continuation to the brake caliper and captures particles created in the braking process. The new development can be fitted to any existing installation space and can be adapted to different brake sizes and concepts.
For the filter media the engineers opted for a metallic based web. The fibers are resistant to corrosion and are able to withstand the high temperatures on the brake which can arise under extreme circumstances. In order to maximize the effective filter surface area and retain as much dust as possible, the filter material in the housing is arranged in pleats and bags. The experts at MANN+HUMMEL subjected the filter system to extreme conditions on the brake test bench. The result was impressive with the filter reliably retaining up to 80 percent of the particles generated in the braking process. That helps the environment, contributes towards improving the air quality and as a positive side effect prevents the soiling of wheel rims and brake systems.
