Lifting Points – Select models have various lifting points
located on the drive frame and bearing plates.
Vibration Isolation – True vibration isolators contain
two independent studs with rubber neoprene to support
the drive assembly and wheel for long life and quiet
operation. No steel-on-steel contact.
Drive Assembly – Belts, pulleys and keys are oversized
by 150% of driven horsepower. Machined cast pulleys are
adjustable for final system balancing. Belts are static-free
and oil-resistant.
Windband – One-piece, heavy-gauge aluminum, with a
rolled bead for extra strength, directs exhaust air away
from the mounting surface.
Leakproof Construction – One-piece windband is
continuously welded to the curb cap for leakproof
protection on XCUE and XCUBE, sizes 099 through
300 and all sizes with UL/cUL 762. XRUD models utlize
leakproof brazed junction.
Mounting Holes – Aluminum curb cap has pre-punched
mounting holes to ensure correct attachment to the roof.
Drain Trough – Allows for one-point drainage of water,
grease and other residue.
Internal Conduit Chase
(not shown) – For easy internal
electrical wiring in applications not subject to NFPA.
Name Plate
(not shown) – Permanent stamped aluminum
plate for exact model and serial identification number.
Seismic Certification
– Certified to IBC 2015, ASCE 7-10 and
California OSHPD certification standards for all seismic
design categories. OSHPD OSP# 0148-10, SDS Value 2.28,
Maximum Certification Size 480 (XCUE/XCUBE only).
High Wind /Hurricane Zone Certification
– Miami-Dade
NOA for high wind and hurricane zones.

Wheel – Backward-inclined, non-overloading centrifugal
wheel is utilized to generate high-efficiency and minimal
sound. Wheel cones are carefully matched to the venturi
for maximum efficiency. Each wheel is statically and
dynamically balanced, for long life and quiet operation.
Disconnect Switch – NEMA-3R switch is factory mounted and
wiring is provided from the motor as standard
(other switches are available). All wiring and electrical
components comply with the National Electrical Codes
(NEC) and are either UL/cUL Listed or Recognized.
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.
Bearings – 100% factory tested and designed specifically
for air handling applications with a minimum L10 life in
excess of 100,000 hours (L50 average life of 500,000 hours).
Motor – Carefully matched to the fan load and mounted
out of the airstream.
Motor Cover – Aluminum construction(XCUE/XCUBE only).
Stainless steel fasteners are attached for easy removal and
access to the motor compartment and drive assembly.
Stainless Steel Fasteners – Allows for easy removal and
access to the motor compartment and drive assembly.
Motor Cooling – Cooling fins located on top of the fan
wheel draw outside air through a large breather tube,
directly into the motor compartment. Positive motor
cooling with fresh air results in maximum motor life.
