Caution is necessary in
selecting blowers for series installation. It is generally accepted
that most pre-engineered blowers are capable of withstanding twice
their catalog rated static pressure. In other words, where two blowers
are installed in series the second blower housing should withstand the
higher pressure. There is, however, a need for concern when the
combined pressure exceeds twice the rated static pressure for one
blower. In series applications involving three or more blowers, or in
any system in which positive or negative pressure exists prior to the
consideration of the blowers, special housing reinforcement may be
necessary.
