ROOTS™ 416 TRI RAM Blower

Model: 416 TRI RAM

The ROOTS™ 416 TRI-RAM rotary positive displacement blower combines historic 1914 tri-lobe compression concepts with modern pulse-dampening mechanics to achieve supreme operational smoothness. It is built for industrial facilities that require higher airflow capacity with smooth and controlled operation. Pushing air streams up to 1412 CFM, this commercial-grade air machine relies on an integrated backflow relief channel to neutralize harsh pressure waves before they travel downstream. Built with an unyielding cast-iron main body and an adaptable top or bottom-shaft setup, it ensures highly reliable, quiet gas delivery across intensive industrial manufacturing systems.

Roots 416 Tri-RAM Design and Features

Tri-lobe impellers reduce vibration and downstream airflow pulsation

WHISPAIR™ discharge design delivers quieter operation than conventional tri-lobe blowers

High-strength integral-shaft ductile iron impellers maximize volumetric efficiency

Cast-iron headplates and rigid cylinder construction support long-term durability

Carburized alloy steel spur timing gears, taper-mounted, and locknut secured for lasting alignment

Cylindrical roller bearings handle V-belt side loads while extending bearing service life

Piston ring seals at headplate shaft openings minimize internal air leakage

Hydrodynamic oil seals keep lubricant out of the air chamber

Integrated thrust control adds mechanical stability under varying load conditions

Splash oil lubrication at both ends with sight glasses for easy maintenance checks

Aluminum drive end and gear covers reduce overall unit weight

Detachable steel mounting feet and drive shaft extension support horizontal or vertical installation
