INLINE FANS | 1 7
Cabinet Construction – The fan housing is constructed
of rigid structural members and formed galvanized steel
panels. Aluminum construction is optional in all XIB sizes
70-300 and XID sizes 60-160.
Wheel – An aluminum, backward-inclined, non-overloading,
centrifugal wheel is utilized to deliver maximum efficiency.
Each wheel is statically and dynamically balanced.
Duct Collars – Inlet and discharge duct collars are provided
for easy duct connection. The square design also provides
a larger discharge area than tubular centrifugal and vane
axial fans, so outlet velocities are reduced for quieter
operation.
Drive Frame – Constructed from heavy-gauge steel. Belt
adjustment is accomplished by loosening fasteners, sliding
the motor plate and re-tightening fasteners.
Motor – Permanently lubricated, sealed ball bearing motors
are selected to provide years of trouble-free operation with
minimal maintenance.
Bearings – 100% factory tested and designed specifically
for air handling applications with a minimum L10 life
in excess of 100,000 hours (L 50 average life of
500,000 hours).
Drive Assembly – Drives are sized for a minimum of 150% of
driven horsepower. Machined cast iron pulleys are factory
set to the required RPM and adjustable for final system
balancing. Belts are static-free and oil resistant.
Fan Shaft – Precisely sized, ground, and polished so the first
critical speed is at least 25% over the maximum operating
speed. Close tolerances, where the shaft makes contact
with bearings, results in longer bearing life.
Disconnect Switch – NEMA-1 disconnect switch is factory
mounted and wiring is provided from the motor as
standard. All wiring and electrical components comply
with the National Electric Code and materials are UL Listed.
Other NEMA enclosure disconnect switches are optional.
Access Panels (not shown) – The cabinet construction
features two side access panels. Access panels permit
easy access to all internal components.
