The Ecoclean SealTrack™ Endless Belt filter system (STEB) provides high-clarity filtration for machining and grinding operations. Patented SealTrack™ endless belt technology creates a continuous positive seal around the filter belt, preventing migration under vacuum pressure. The seal is maintained even when the filter media is indexed. STEB's continuous positive seal is proven and reliable: no backup filtration is required because chips virtually cannot bypass around the STEB's side seal.
