ROOTS™ 722 TRI RAM Blower

Model: 722 TRI-RAM

The ROOTS™ 722 TRI-RAM positive displacement blower captures decades of industrial field evolution, utilizing historic 1914 tri-lobe compression foundations alongside cutting-edge pulse control. Moving a massive 3312 CFM of air, this severe-duty machine actively dampens line shocks and reduces the working plant's noise levels through an engineered fluid bypass. Equipped with an unyielding, fully cast-iron enclosure and multi-positional support steel, it provides dependable, high-volume performance for demanding continuous-operation plant applications.
