ROOTS™ 413 TRI RAM Blower

Model: 413 TRI-RAM

Building on over a century of Roots tri-lobe engineering principles first developed in 1914, the ROOTS™ 413 TRI-RAM steps up airflow capacity within the Roots™ Tri-RAM™ Positive Displacement Blowers family to handle mid-range industrial pressure and vacuum systems with noticeably quieter, smoother operation. Rated to 1227 CFM, 15 PSI, and 4750 RPM, its tri-lobed ductile iron impellers paired with WHISPAIR™ discharge technology reduce vibration, minimize downstream pulse, and deliver the kind of consistent airflow performance that both operators and downstream equipment genuinely benefit from.
