A new combined multi-tube cyclone air filter is introduced. This filter offers the following advantages over existing filters: Compact, light weight, easy to manufacture, ideal for first-time filtration of large volumes of air. It can be used in electric locomotives, diesel locomotives and diesel vehicles. This article describes the structure of this air filter and its aerodynamic drag characteristics and the ability to remove dust, water droplets, snowflakes.
