High Pressure Centrifugal Blowers in Series by Canada Blower

Canada Blower Co. has developed systems of high pressure fans in series to obtain the static pressure, previously unachievable in a single-stage centrifugal blower. Series and parallel systems are often used for ventilation, provided to fit over the normal capacity single stage fan. For systems that require high pressure ststic, especially high pressure and high temperature (where Standard multi-stage pumps, screw, or regenerative blower can not be used) Series single stage fan. Many times additional blower in the system can be an advantage. For example, where two in-line fans are operational and broke, all the others may be able to “limp” the system, carried out during maintenance work needed. Supported by blowers can be operated often allow a limited production, while the other is being repaired. Also, there are cases where you could continue with the fan function to prevent or at least minimize, system or property damage from things such as high temperatures obtained contaminated air stream. Another advantage of fans in series is that space availbale. If the system should be expanded and needs increaases CFM, the space allocated for the original fan can not big enough for a single large fan, which may, but big enough to get fans installed two smaller lines, the pressure required . Another advatage potentail for the series is the first operation of likehood cost savings. Although each case must be evaluated individually, it is often cheaper, two “minor”, select fans with smaller motors and their respecto unit as a “blower choose to do more work. Connected in series fans are the result of an exhausting fan input of another fan. Connecting blowers so that the high static pressures are achieved. This is done as a second blower adds the ability to pressure the system, increasing the capacity of the capacity of the first fans. Ideally, two identical fans were installed in series in the same CFM fans on the edge of the second as the recruitment of the first episode, and almost twice as high as the static pressure, is evaluated for the fan alone. However, some changes will lead to compression in both air flow and the combined pressure due to the tendency of ‘air pressure. A good understanding of how the influence atnoshperic pressure and absolute temperature, the density is not required. Both factors are involved in the correct selection of fans. The density is directly proportional to the pressure and is inversely proportional to absolute temperature (degrees Rankine). Caution is in the selection of fans for the series installtion needed. And ‘generally accepted that most pre-built to withstand the fans twice their catalog are nominal static pressure. Should, in other words, where two fans are mounted in series with the second fan housing to withstand higher pressure. However, it is a concern if the combined pressure of twice the nominal static pressure exceeds a blower. In many applications where three or more fans, or any system in which positive or negative pressure is present before the test, the fan, the strengthening of special accommodations may be necessary.
