INLINE FANS | 2 1
ELECTRICAL ACCESSORIES
Toggle type and heavy-duty disconnect switches are available for
positive electrical shut off and safety in servicing fans.
OPTIONS AND ACCESSORIES XID, XIB, XQEI, AND XTIF
Belt Guard – Belt guards are totally enclosed to provide protection
from rotating pulleys and belts. Belt guards meet OSHA guidelines.
Motor Cover (Weatherhood) – Weatherproof motor covers shield
the motor and drive components from dust, dirt and moisture
when used in outdoor applications. Motor covers also provide
protection from rotating pulleys and belts. The motor covers
meet OSHA guidelines.
Inlet & Outlet Companion Flanges – Companion inlet flanges and
outlet flanges with pre-punched holes are available for all fan sizes
in painted steel construction.
Inlet & Outlet Guards – Removable inlet and outlet guards provide
protection for personnel and equipment in non-ducted installations.
These guards meet OSHA guidelines.
Inspection Door – Bolted or hinged doors provide access for
cleaning or inspection.
Inspection Section – Inspection sections serve as a length of duct
that can be easily removed to provide complete access to the fan
for servicing. Each section includes a bolted inspection door.
Isolators – Both, base mount or hanging isolators, are available in
either neoprene or spring mounts. The isolators are furnished in
sets of four and sized to match the weight of each fan.
Mounting Rails – Mounting rails are required for horizontal mounting
of XQEI and XTIF fans when the motor is to be located in the 3 or
9 o’clock position. Mounting rails are also recommended for all
vertically mounted inline fans.
Aluminum Construction – Aluminum construction is available for
direct drive sizes 60-160 and belt drive sizes 70-300.

Motor (VG) XID only – No shaft grounding
required regardless of the turndown. Bearing life is greater since
the motor runs cooler the further it is turned down. No voltage or
current spikes as in VFD controlled motors.
Speed Controllers – Available for use with shaded pole and
permanent split capacitor (PSC) open motors on model XID fans.
They provide an economical means of system balancing with direct
drive fans.
Greenheck Vari-Green

Controls – Electronic commutation uses
electronic circuitry to control the motor’s functions. Solid-state
circuitry controls the output of power and the speed of rotation.
Internal circuitry converts 115-volt single-phase AC power to DC
voltage for increased efficiencies and full controllability of speed.
Direct Drive Motor Cover – Formed galvanized steel motor covers
are available to isolate direct drive motors from the airstream.
When motor covers are furnished, vents to the exterior of the fan are
provided to ensure sufficient motor cooling.
Dampers – Motorized parallel blade dampers (Model WD-330)
are available for duct mounting. These dampers feature sturdy
galvanized frames with pre-punched mounting holes, aluminum
blades with felt edges and a balanced design for minimal resistance
to airflow.
Control Dampers – Square opposed blade volume control dampers
(Model VCD) are available for duct mounting. These dampers (not
available with UL/cUL 762) feature sturdy galvanized frames with
pre-punched mounting holes, steel blades with vinyl seals and
flexible metal jamb seals. A balanced design results in minimal
resistance to airflow.
Coatings – Wide variety of coatings and colors are available.
Decorative coatings are available in 16 different colors. Protective
coatings are available in a choice of five electrostatic applied
powders providing an available selection for
most environments.
Wiring Pigtail – Allows direct hook-up to the power supply
eliminating field wiring at the fan.
Pressure Probe – A 1/4-inch diameter tube in the fan venturi allows
hook-up to the manometer for static pressure measurement.
Insulated Housing – For noise reduction and condensation control,
the interior of the fan housing can be lined with a fiberglass duct
liner (1/2 and 1 inch being standard). The optional motor cover can
also be insulated.
The table below depicts the dB reduction that can be obtained
in each octave band for the insulated housing and motor
cover together.
