For dilute phase pneumatic conveying blower lines running above 12 psi problems can arise with rotary PD blowers, roots blowers, as this is near the upper end of their operating range. At these pressure levels, PD blowers may have less ability than desired to achieve the necessary pressure rise to overcome the formation of plugs. Furthermore, PD blower or roots blower longevity may be compromised at levels above 12 psi and high duty cycles. Inovair turbo blowers on the other hand, with much higher pressure capabilities, are able to achieve the desired rise to overcome potential plugs at high psi levels, and remain extremely durable.
Facility downtime is expensive, whether caused by a plugged line or a failing blower. A facility experiencing downtime created by shorter than expected PD blower life and recurring plugged lines, as well as seeking energy reduction opportunities, installed an Inovair Complete Blower System (CBS). The Inovair turbo blower has not only generated energy savings approaching 30%, it has also shown the ability to generate a larger pressure rise than the PD blower or roots blower it replaced, reducing the exposure to plugs. Additionally, the noise levels from PD blowers or roots blowers running at high pressure can become unacceptable, requiring additional investment in silencers and/or noise isolation. With the quiet design of the Inovair CBS, the unit was placed outside the blower room freeing up space in a very crowded environment.
