Direct driveArrangement 4PFD packaged fanswith reinforced
airfoil wheels are designed for higher pressure supply air
applications, such as packaged boilers.
Steep, stable pressure curve allows
near constant air delivery.Three
wheel designs for all standard
motor speeds offer a broad
performance range.

Heavy radial wheels are recommended for pollution
control applications, such as continuous duty of
primary air on burners, pulverizers,
fluidizers and scrubbers.Options
include abrasion and corrosion
resistant constructionmaterials.
Variablewidths and diameters
provide exact performancewith
direct drive convenience.

All custom fans are availablewith
API 673 and 560 construction
features tomeet the stringent
demands of the petroleum industry.
Although fans are built for a
variety of refinery applications,
each one is individually
engineered using one of 15
distinct designs to fulfill per-
formance specifications and the
unique demands of the installation.
