XTIF - Inline Fan
All XTIF inline fans are available in two levels of construction to provide
the most efficient and economical selections. Construction differences
between Level 1 and 2 selections include: the impeller, the inlet cone, the
shaft size, and the bearings. The housings for both levels are identical in
material gauge and overall design.
Inlet & Outlet Flanges – Flanged inlets and outlets with mounting
holes are provided for duct connections.
Housing – Housings are continuously-welded steel and powder
coated with Permatector™.
Protective Coating – All steel constructed units are powder coated
with Permatector, a thermosetting polyester urethane. Aluminum
units are uncoated.
Type B Spark Resistance – All fans have aluminum wheels and a non-
ferrous (aluminum) rub ring, which surrounds the fan shaft where
it passes through the drive cover. This construction meets Type B
spark resistant requirements.
Type B or C Spark Resistance – Aluminum construction
is available on the XTIF fans and is an excellent choice for
applications involving moisture or coastal installations.
Easy Access Construction – The easy access option is highly
recommended to allow for inspection, cleaning and service
of internal fan components. By removing one access panel,
service to the wheel, shaft, and bearing assembly is possible
without removing duct connections. In addition, all internal fan
components can be removed from the fan through the easy
access panel.
STANDARD CONSTRUCTION FEATURES
OPTIONAL CONSTRUCTION FEATURES
Bearings – Standard bearings are grease lubricated, self-aligning,
ball type in pillow block mounts. Bearings are selected for a
minimum L10 life in excess of 80,000 hours (L 50 average life of
400,000 hours) at maximum cataloged operating speeds.
Belt & Bearing Tube – Belts, bearings, and drives are protected from
the airstream by heavy-gauge belt tubes and bolted bearing covers
with shaft seals.
Extended Lube Lines – Lubrication lines with grease fittings allow
bearing lubrication without disassembling the fan.
LEVEL 1 CONSTRUCTION
• Maximum pressure capabilities of 2 in. wg (500 Pa)
• Highest efficiencies at static pressures below 1.5 in. wg (375 Pa)
• Riveted, partially welded aluminum wheel construction
• Most economical selection
LEVEL 2 CONSTRUCTION
• Maximum pressure capabilities of 4 in. wg (993 Pa)
• Highest efficiencies at static pressures above 1.5 in. wg (375 Pa)
• Completely welded aluminum wheel
• Increased shaft and bearing diameter
• Increased horsepower and motor frame size capability
Easy access construction is
available on all levels and
sizes of XTIF and is also available
with aluminum construction fans.
