The Roots proprietary WHISPAIR* design reduces stress, vibration and noise in your blower and piping system. Conventional blowers produce downstream pressure pulse waves which buffet your air or gas delivery system up to 120 times per second. These pulses and vibrations can steal power and shorten the life of every bearing, gear and other drive train component. WHISPAIR technology reduces the strength of the blower pulse up to 40%, throughout the air/gas delivery system.

Note 1: Standard drive shaft location is dependent upon frame size: 10xx through 14xx frame sizes - drive shaft is located on the opposite gear end of the machine and is shown in heavy type. 16xx through 20xx frame size - drive shaft is located on the gear end of the machine as shown by dotted lines. For all direct drive applications torsional analysis of the whole drive train is required and in the case of drivers other than electric motors, gear end drive must be specified. Frame sizes 10xx through 14xx can be belt driven with the addition of an optional extra bearing and selection of correct pulley combination.
