ROOTS™ 826 TRI RAM Blower

Model: 826 TRI-RAM

Among the most substantial units in the Roots™ Tri-RAM™ Positive Displacement Blowers series, the ROOTS™ 826 TRI-RAM is built for industrial operations where airflow volume, structural integrity, and long service intervals all carry equal weight. Rated to 4319 CFM, 15 PSI, and 2670 RPM, this 2000-pound workhorse pairs integral-shaft ductile-iron impellers with WHISPAIR™ discharge technology and an all-cast-iron housing to sustain high-output performance with the vibration control and noise reduction that the RAM™ platform's century-long engineering lineage has made its defining standard.
