The client says that this process will only last two years, and they don’t want to use a compressor; therefore we have chosen blowers for this purpose. I would like to ask if rotary vane blowers can meet these requirements? If not, what type of blower should be used? Thank you. The medium is nitrogen, with a flow rate of 125 standard cubic meters per hour. (One manufacturer said that the maximum pressure for single-stage rotary vane blowers is usually 100 KPA, while that for double-stage rotary vane blowers is between 160–180 KPA.)
The Roots blower does not meet the requirements! The maximum two-stage boost is 2BAR. A centrifugal compressor could be considered!
