ROOTS™ 617 TRI RAM Blower

Model: 617 TRI-RAM

The ROOTS™ 617 TRI-RAM positive displacement blower relies on a legacy of tri-lobe engineering stretching back to 1914, enhanced by modern pulsations suppression technology. Pushing air configurations up to 2165 CFM, this premium system incorporates a unique backflow management design to minimize system shocks and acoustic output. Using durable cast-iron framing combined with flexible dual-shaft positioning, it provides highly efficient and consistent air movement throughout large industrial factories.
