ROOTS™ RAM™ WHISPAIR 404 Rotary Positive Displacement Blower
Introducing the ROOTS™ RAM™ WHISPAIR series — spanning Frame 404J through 624J — where the proven reliability of the RAM™ platform meets advanced low-noise engineering. The WHISPAIR 404 delivers up to 396 CFM, operating pressures to 18 PSI, vacuum to 16″ Hg, and speeds to 4000 RPM, while requiring less operating power and producing significantly lower noise levels than standard rotary positive blowers. Featuring a lip-type hydrodynamic drive shaft seal, alloy steel timing gears, cylindrical roller bearings, piston ring air seals, and splash oil lubrication — all CNC-precision manufactured — the WHISPAIR 404 is the go-to choice for industrial facilities where acoustic performance is as critical as airflow reliability.
