ROOTS™ 832 TRI RAM Blower

Model: 832 TRI-RAM

The ROOTS™ 832 TRI-RAM stands as the highest-capacity unit in the Roots™ Tri-RAM™ Positive Displacement Blowers series. It's a flagship industrial blower where over a century of Roots tri-lobe engineering, first conceived in 1914 and continuously refined through the proven RAM™ platform, reaches its fullest expression. Handling up to 5399 CFM at 12 PSI and 2670 RPM, this 2200-pound unit combines integral-shaft ductile-iron impellers, an all-cast-iron housing, and WHISPAIR™ discharge technology to set the standard for high-volume rotary positive displacement blower performance where noise control, structural integrity, and long service life all matter equally.

Roots 832 Tri-RAM Design and Features

Three-lobe impellers protect downstream infrastructure by curbing severe air pulsations

Roots WHISPAIR blower discharge quietens operations by smoothing internal backflow shocks

Integral-shaft ductile iron impellers offer superior strength to maximize operating efficiency

Case-hardened spur timing gears utilize a taper mount and bolt to prevent slippage

Large cylindrical roller bearings easily absorb high side loads from V-belt drives

Mechanical thrust control stops internal rotor shifting under heavy load changes

Tough piston rings minimize process gas leakage through the headplate openings

Hydrodynamic oil seals form an absolute barrier to keep lubricant out of the air stream

Dual-end splash oil reservoirs feature clear sight glasses for fast maintenance checks

Detachable steel mounting feet adapt the unit easily to horizontal or vertical setups
