INLINE FANS STANDARD AND OPTIONAL CONSTRUCTION FEATURES
XQEI - Inline Fan
The XQEI inline fan has different wheel designs
with different performance characteristics.
Class I wheels are optimized for performances
involving low pressures and high volumes.
Class II wheels are designed for a steeper fan
curve with high-pressure capabilities.
Cabinet Construction – Tubular housings are constructed of welded
steel to eliminate air leakage. Integral straightening vanes are
constructed from steel and welded into place.
Wheel – Mixed Flow – Fabricated wheels are constructed from steel.
The blade profiles are angled and contoured for the most efficient
and quiet performance.
Bearings – Standard bearings are premium air handling quality,
grease lubricated, self-aligning, ball or roller type. Bearings are
selected with a basic rating fatigue life L10 per ABMA standards, in
excess of 80,000 hours (L50 at 400,000 hours) at the maximum
operating speed for the QEI-I/II in the horizontal position.
Bolted Access Door – A bolted access door provides an opening
through the fan housing for cleaning or visual inspection of the
wheel. A hinged access door is available as an accessory.
Type B or C Spark Resistance –Type B or C Spark Resistance – XQEI
is available with spark resistant designs suitable for applications
that involve flammable particles, fumes or vapors. Spark resistant
construction options adhere to guidelines defined with AMCA
Standard 99-0401-10.
Spark B Sizes 9 - 33 –The fan wheel is
constructed of a non-ferrous material
(aluminum). The aluminum bearing
cover surrounds the driven bearing,
shielding it from the airstream.
Spark C All Sizes –The inlet cone is
constructed of non-ferrous material
(aluminum). The aluminum bearing
cover surrounds the driven bearing,
shielding it from the airstream.
STANDARD CONSTRUCTION FEATURES
OPTIONAL CONSTRUCTION FEATURES
Belt Guard – A totally enclosed belt guard provides protection from
rotating pulleys and belts. Belt guards meet OSHA Standards.
Slip-Fit Duct Connection – Inlets and outlets are designed with
extended collars for slip-fit duct connections as standard.
Adjustable Motor Bases – Rigid, heavy-gauge steel motor bases
are welded to the fan housing and include heavy-duty adjustment
screws for belt tensioning.
Extended Lube Lines – Units have nylon lubrication lines with
grease fittings that allow bearing lubrication without disassembling
the fan. Grease fittings are mounted on the outside of the
fan housing. Smaller frame sized motors are typically sealed
and not lubricatable.
Permatector™ Coating – A thermosetting polyester urethane
electrostatically applied to provide uniform thickness and a
clean appearance. Permatector™ coatings also provide excellent
corrosion characteristics for general applications, both indoor
and outdoor.
