1.0 GENERAL DESCRIPTION
1.1 DEFINITIONS
A vaneaxial fan is an axial fan with a vane section
downstream of the rotor. The vane section converts the rotat-
ing component of the airflow into axial flow and pressure,
increasing the static pressure capability of the rotor.
An adjustable pitch rotor is one where the blade angle
can be changed, but only when the rotor is stationary.
A variable pitch rotor, also called controllable pitch,
is one where the blade angle can be changed while the fan is
running.
1.2 ARRANGEMENTS
Axial fans are available in two different configurations,
defined as follows:
Arrangement 4, Type 2 — The rotor is mounted
directly on the motor shaft, and the motor is upstream of the
rotor, with both rotor and motor enclosed in the fan tube.
Arrangement 4, Type 3 — The rotor is mounted
directly on the motor shaft, and the motor is upstream of the
rotor, but supported outside the fan tube.
Aerovent axial fans offer the following combinations
of these basic definitions, using the nomenclature shown:
Description AXICO
Vaneaxial Fan X
Adjustable Pitch FPDA
Variable Pitch:
Electric Control FPMC
Hand Crank Control FPMC
Pneumatic Control FPAC
Arrangement 4, Type 2 X
Arrangement 4, Type 3 X
1.3 APPLICATION
If the application requires that the inlet to the fan be
ducted, Arrangement 4 Type 3 cannot be used. All the other
arrangements are furnished with an inlet duct flange to which an
inlet duct or an inlet bell can be fastened.
Arrangement 4 Type 3 fans are ideally suited for ple-
num applications with a free inlet condition as this arrange-
ment can permit the fan to be placed much closer to the coils
or filters upstream.
1.4 ACCESSORIES
Various accessories are available for AXICO fans.
a. Inlet bell and screen (standard on Arrangement 4 Type 3
fans)
b. Inlet cones
c. Vane section (standard on AXICO fans)
d. Discharge diffuser sections (two types)
e. Acoustic discharge diffuser sections
f. Flexible duct connections and band clamps
g. Gravity backdraft dampers
h. Vibration isolation
1.5 OPTIONS
AXICO fans may be furnished with various options to
meet job requirements:
a. Legs for floor mounting.
b. Brackets for vertical, horizontal, or angular mounting from
the floor or ceiling.
c. Electric operator or manual hand-wheel for adjustment of
AXICO FPMC when in operation, or quadrant and clamp
adjustment when the fan is turned off
d. AXICO fan operators and positioners located at other than
top dead center
1.6 NAMEPLATE NOMENCLATURE
The model number information on each fan nameplate is
explained on page 14.
2.0 INSTALLATION
2.1 RECEIVING/INSPECTION/STORAGE
Each Aerovent fan is shipped on a wooden pallet and
is covered with plastic for weather protection.
Carefully inspect the fan upon arrival for damage
incurred during shipment. Immediately report any damage to
both the factory and the carrier.
For short-term storage prior to installation, the fan
should remain covered with plastic wrap on the shipping pallet
and stored in a clean, dry location away from the elements. If
storage is to be for a period longer than 30 days, see page 15
for long-term storage instructions.
