Pulsation-free: Free flow without pulsation

Due to the construction and operation of our blowers fluctuations of pressure are prevented, as long as the blower is operated above the surge limit.

If operated by a motor with constant rotational speed with constant environmental and operating conditions, pressure and flow capacity should remain constant. If operating conditions are changed for example by opening or closing butterfly valves the pressure will change according to the performance curve characteristics.

After reaching the operational or design point, when no conditions are changed, the pressure should be constant. Fluctuations or pulsations, which are present with rotary piston blowers (2 or 3 lobe construction), are not possible with centrifugal blowers.
