Air Filtration Systems

Our range of mechanical filtration systems includes the SpinfloTM Self-Cleaning Inertial Air Filtration System used in engine air intake filtration and Centrifugal Cleaners used in locomotive lube oil filtration.Spinflo filters consist of an array of spin-tubes designed to check tough contaminants including soot, rain, snow and sawdust while offering minimal resistance to the flow of air. It is the only fully indigenous inertial air filtration system for use in railroad applications, removing up to 98% contaminants at the primary filtration stage itself.The Centrifugal Lube-Oil Cleaner is a ‘fit-and-forget’ mechanical lube-oil filtration system developed indigenously for the first time by Prag. Today, the system is installed in more than 3,000 locomotives and has led to effectively doubling the life of media-based lube-oil filters in addition to extending the lube-oil service life.
