The specifications to consider when selecting regenerative blowers
include: maximum free air delivery, maximum pressure, and motor power.
Free air delivery (FAD) is the actual air produced by the compressor
pump at the rated pressure. Maximum FAD is usually rated at a pressure
somewhat less than the maximum pressure available. Volume per unit time
is the unit of measure. Maximum pressure is the maximum level of air
pressure generated by the compressor. Typically, these units are
referenced to one atmosphere, as in psig or psi gauge. Note that
maximum flow may not occur at maximum pressure. Motor power is the
rated power of motor or engine driving compressor pump.
Buffalo Blower axial flow
fans are best buy for many industrial air moving jobs. Generally, an
axial costs considerable less than a quality centrifugal fan delivering
the same volume and pressure. They cost less to install since they are
lighter, requiring minimum structural support. They can be duct
mounted, taking up little space. Direct drive models mean faster
start-up and the abscence of V-belt drive and fan bearings lowers
maintenance costs. Adjustable and Controllabel Pitch Vaneaxial Fans
feature an adjustable pitch blade wheel that permits matching your
pressure/volume requirements exactly, and lets you make on-the-job
adjustments to compensate for system changes. Buffalo Blower Tubeaxial
Fans have fixed blade wheels in capacities up to 100,000 cfm and to 5"
total pressure.
