Advantages of Rotary Positive Displacement Blowers Versus Centrifugal Blowers

Centrifugal blowers are generally more expensive than positive displacement blowers. Centrifugal blowers operate at high speeds (up to 30,000 RPM) and, as such, rely heavily on instrumentation which monitor many conditions to protect against unfavorable operating conditions. If such instrumentation fails, or is not utilized, a centrifugal blower will often fail to the point that replacement is the only repair alternative. A positive displacement blower will provide definite warnings prior to failure allowing the user to remove the unit from…
