The Highlights: Dear customers and KEMPER partners, In 1977, KEMPER was founded to make the metalworking environment safer, cleaner and more efficient. Since then, thanks to its pioneering spirit and wealth of innovative solutions, KEMPER has built a reputation as a reliable and application-oriented manufacturer for its distribution partners. This approach has proved a success for more than 35 years and has resulted in the repeated creation of new, groundbreaking products and services. 360 intake This new main catalogue has been completely revised with the aim of Bumper» Displacement flow achieving principle, speed and clarity. Various navigation aids and home Consistent pages intake of the contaminated air recommended facilitate by health searches and safetyin the new catalogue. The tower is Short, equipped structured with product descriptions provide a good overview, specifc rapid impact recognition protection of the most impor- bodies tant product characteristics and the differences between them.» Minimization of heating costs due to air recirculation See and for air yourself. distribution Happy browsing! 360 Low-impulse air circulation» Cost-effective installation or retrofit, No dust distribution into clean areas, as no ductwork is needed as barely any air turbulence is created» More Information on page 67 Björn Kemper Gerd Kemper
