ROOTS FLO® 412 Rotary Positive Displacement Blower

Model: ROOTS FLO® 412

The Roots-Flo Rotary Blower 412 handles demanding volumetric challenges, moving up to 1207 CFM. Built with premium ductile-iron impellers and rigid ASTM class 30B headplates, this 330-pound system excels in rigorous pneumatic grain relocation. Specialized cylindrical roller bearings accommodate high radial belt pull, while ground alloy steel spur gears operate smoothly within dual oversized oil reservoirs to maintain ideal internal thermal conditions.

Warranty Information

Impellers

Dynamically balanced ductile iron impellers with integral shafts are manufactured to ASTM 536 Class 60-45-12 and 80-60-3 standards for additional strength during maximum load operation. Computer-engineered impeller profiles help improve airflow efficiency and overall blower performance.

Bearings

Extra capacity cylindrical roller bearings are designed to deliver extended service life under high-speed and heavy-load conditions. The drive shaft bearing system offers significantly longer operational life compared to standard ball bearing assemblies commonly used in competitive units.

Gears

Precision spur timing gears are manufactured from SAE 8620 steel, carburized, and ground to 58 to 62 RC hardness for dependable continuous duty performance without generating damaging thrust loads during operation.

Seals

Main air seals use piston ring-style sealing to reduce internal leakage. Bearing and drive shaft oil seals feature Viton lip construction engineered for severe duty industrial environments and long-term reliability.
