Vaneaxial Fans

Available Vaneaxial Fan Designs

Belt Driven – Type B and P

The Type B and P belt driven vaneaxial fan designs

incorporate internal guide vanes welded around the

inner shell bearing support. A wheel inspection sec-

tion to facilitate cleaning the cast solid aluminum pro-

peller can be provided as an option. If this section is

not furnished it is necessary to field install an access

door in the duct next to the inlet or to remove the

fan from the duct system for cleaning of the propeller

and guide vanes. For high temperature or corrosive

applications, the Type B can be reconfigured with

an external guide vane section similar to the Type T

shown below.

Direct Drive – Type B and P

The Type B and P direct drive vaneaxial fan designs

incorporate internal guide vanes welded around a

circular bulkhead/motor base plate assembly. A wheel

inspection section to facilitate cleaning the cast solid

aluminum propeller can be provided as an option. If

this section is not provided it is necessary to field

install an access door in the duct next to the fan

inlet or to remove the fan from the duct system for

cleaning of the propeller and guide vanes.

Belt Driven – Type W & J

The Type W belt driven vaneaxial fan design incor-

porates internal guide vanes welded around the inner

shell bearing support. For Type W, a wheel inspec-

tion section to facilitate cleaning the adjustable pitch

aluminum propeller can be provided as an option. If

this section is not furnished it is necessary to field

install an access door in the duct next to the fan

inlet or to remove the fan from the duct system for

cleaning of the propeller and guide vanes. For Type

J, a propeller access door is provided as standard.

Direct Drive – Type W & J

The Type W direct drive vaneaxial fan design incorpo-

rates internal guide vanes welded around the circular

bulkhead/motor base plate assembly. For Type W,

a wheel inspection section to facilitate cleaning the

adjustable pitch aluminum propeller can be provided

as an option. If this section is not furnished it is

necessary to field install an access door in the duct

next to the fan inlet or to remove the fan from the

duct system for cleaning of the propeller and guide

vanes. For Type J, a propeller access door is pro-

vided as standard.

area can facilitate inspection of the welded steel

propeller and can be provided as an option. If wheel

cleaning capability is desired, it is necessary to field

install an access door in the duct next to the inlet or

to remove the fan from the duct system for cleaning

of the propeller and guide vanes.

Belt Driven – Type T The guide vanes are built into a removable section of duct adjacent to the propeller and can be taken completely out for cleaning without disturbing the fan. Removing the vane section also provides access to the cast solid aluminum propeller. The construction of this fan lends itself to high temperature or corrosive applications. As an alternative, an optional access door can be provided in the fan housing for inspection and cleaning of the propeller.

Type J - Adjustable Pitch Wheel Blade Angle Adjustment The blades are set at the factory to the blade angle that gives the performance specified on the order. This angle should be checked prior to start-up. The patented wheel construction uses friction and centrifugal force to hold the blades in place. No disassembly of the wheel is required to change the blade angles. If it is necessary to change the blade angle, the following procedure should be used: 6.

Suggested Installations Same Size Duct Normal fan installation. Rating tables are based on this arrangement. Variations in installations as indicated below may provide more economical fan performance but may require higher installation costs. AXIAL FLOW FAN Tapered Discharge Allows regain of a portion of the velocity pressure to static pressure. The fan can then be picked at a lower pressure for more economical operation.
