FORWARD CURVED
Used extensively for high volume, low pressureForward Curved Fan
H & V work or light duty applications. These fans
do not have non-overloading characteristics
therefore dampers are recommended to prevent
motor overloading if system pressure conditions are not defined accurately.

BACKWARD CURVED AEROFOIL
Used for H & V low or medium pressure
work where efficiency and quietness is
important. These fans have non-overloading
characteristics.

PADDLE BLADE/RADIAL BLADE
Used extensively for dust, wood waste,
paper refuse and high temperature gas fan
applications. These fans do not have nonoverloading
characteristics therefore
dampers are recommended to prevent
motor overloading if system pressure
conditions are not defined accurately.

BACKWARD INCLINED/ BACKWARD CURVED/H.P. BLOWERS
Used for pressures varying from 4” WG to 60”WG
and applications with light dust loadings, these
fans have non-overloading characteristics and are
more efficient than the Forward Curved.

HIGH PRESSURE BLOWERS
Used where there is a requirement for high
velocities e.g. air curtains refuse conveying, furnace
etc. Normal discharge velocities 3000-6000 feet
per minute.
