Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 13349 was prepared by Technical Committee ISO/TC 117, Industrial fans.

Introduction
This International Standard reflects the importance of a standardized approach to the terminology of fans.
The need for an International Standard has been evident for some considerable time. To take just one example, the
coding of driving arrangements differs from manufacturer to manufacturer. What one currently calls Arrangement 1
may be known by another as Arrangement 3. The confusion for the customer is only too apparent. For similar
reasons, it is essential to use standardized nomenclature to identify particular parts of a fan.
Wherever possible, in the interests of international comprehension, this International Standard is in agreement with
similar documents produced by Eurovent, AMCA, VDMA (Germany), AFNOR (France) and UNI (Italy). They have,
however, been built on where the need for amplification was apparent.
Use of this International Standard will lead to greater understanding among all parts of the air-moving industry. It is
hoped that manufacturers, consultants, contractors and users will adopt and refer to this International Standard as
soon as possible.

Industrial fans — Vocabulary and definitions of categories
1 Scope
This International Standard provides a vocabulary and defines categories for general purpose industrial fans and
their component parts. It is applicable to any fan used for industrial purposes, including the ventilation of buildings
and mines, but excluding ceiling, pedestal and similar circulation types of fans such as those commonly used for
non-industrial purposes.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards listed below. Members of IEC and ISO maintain
registers of currently valid International Standards.

3 Definitions
For the purposes of this International Standard, the following definitions apply.
3.1
fan
rotary-bladed machine which receives mechanical energy and utilizes it by means of one or more impellers fitted
with blades to maintain a continuous flow of air or other gas passing through it and whose work per unit mass does
not normally exceed 25 kJ/kg
NOTE 1 The term "fan" is taken to mean the fan as supplied without any addition to the inlet or outlet, except where such
addition is specified.
NOTE 2 Fans are defined according to their installation category, function, fluid path and operating conditions.
NOTE 3 If the work per unit mass exceeds a value of 25 kJ/kg, the machine is termed a turbocompressor. This means that,
for a mean stagnation density through the fan of 1,2 kg/m , the fan pressure will not exceed 1,2 ´ 25 kJ/kg, i.e. 30 kPa, and the
pressure ratio will not exceed 1,30 since atmospheric pressure is approximately 100 kPa.

3.2
air
in this International Standard, an abbreviation for the expression "air or other gas"
3.3
standard air
by convention, air with a density of 1,2 kg/m
3.4 Fan installation types according to the arrangement of ducting (see figure 1)
3.4.1
installation type A
installation with free inlet and free outlet
[ISO 5801 and ISO 5802]
3.4.2
installation type B
installation with free inlet and ducted outlet
[ISO 5801 and ISO 5802]
3.4.3
installation type C
installation with ducted inlet and free outlet
[ISO 5801 and ISO 5802]
3.4.4
installation type D
installation with ducted inlet and ducted outlet
[ISO 5801 and ISO 5802]
3.5 Types of fan according to their function
3.5.1
ducted fan
fan used for moving air within a duct
NOTE Such a fan may be arranged in an installation of type (B), (C) or (D) (see figures 2, 3 and 5).
3.5.2
partition fan
fan used for moving air from one free space to another separated from the first by a partition having an aperture in
which or on which the fan is installed
NOTE Such a fan should be arranged in an installation of type (A) (see figure 6).
3.5.3
jet fan
fan used for producing a jet of air in a space and unconnected to any ducting (see figures 7 and 8)
NOTE The air jet may be used for example for adding momentum to the air within a duct, a tunnel or other space, or for
intensifying the heat transfer in a determined zone.
3.6 Fan types according to the fluid path within the impeller
3.6.1
centrifugal fan
fan in which the air enters the impeller with an essentially axial direction and leaves it in a direction perpendicular to
this axis (see figure 2)
© ISO
ISO 13349:1999(E)
NOTE 1 The centrifugal fan is also known as a radial-flow fan.
NOTE 2 The impeller may have one or two inlet(s) and may or may not include a shroud and/or a backplate (centreplate)
(see figure 14).
NOTE 3 The impeller is defined as "backward-curved or inclined", "radial" or "forward-curved" depending on whether the
outward direction of the blade at the periphery is backward, radial or forward relative to the direction of the rotation (see
figure 14).
NOTE 4 A centrifugal fan may be of the low, medium or high pressure type, according to the aspect ratio of fan inlet diameter
to outside diameter of the impeller. These terms indicate that the pressure generated at a given flowrate is low, medium or
high.
NOTE 5 Figure 5 shows a cross-section through a family of impellers having the same inlet diameter. Fans with ratios of fan
inlet/outside impeller diameter of greater than approximately 0,63 are considered "low aspect ratio", and lower than
approximately 0,4 are considered "high aspect ratio". Medium aspect ratio centrifugal fans are intermediate between these two
figures.
NOTE 6 The impeller diameter and the casing scroll radii increase with the pressure range for which the fan is designed.
NOTE 7 These categories will also be affected by the ability to run at the necessary peripheral speed (see 5.2 and table 1).
3.6.2
axial-flow fan
fan in which the air enters and leaves the impeller along essentially cylindrical surfaces coaxial with the fan (see
figure 3)
NOTE 1 An axial-flow fan may be of the low, medium or high pressure type according to the aspect ratio of hub diameter to
outside impeller diameter. These terms indicate that the pressure generated at a given flowrate is low, medium or high.
NOTE 2 Figure 10 shows a cross-section through a family of impellers having the same outside diameter. Fans with ratios of
hub/outside impeller diameter of less than approximately 0,4 are considered "low aspect ratio", and greater than approximately
0,71 are considered "high aspect ratio". Medium aspect ratio axial fans are intermediate between these two figures.
NOTE 3 These categories will also be affected by the ability to run at the necessary peripheral speed.
3.6.2.1
contra-rotating fan
axial-flow fan which has two impellers arranged in series and rotating in opposite directions
3.6.2.2
reversible axial-flow fan
axial-flow fan which is specially designed to rotate in either direction regardless of whether the performance is
identical in both directions
3.6.2.3
propeller fan
axial-flow fan having an impeller with a small number of broad blades of uniform material thickness and designed to
operate in an orifice
3.6.2.4
plate mounted axial-flow fan
axial-flow fan in which the impeller rotates in an orifice or spigot of relatively short axial length, the impeller blades
being of aerofoil section
3.6.2.5
vane axial fan
axial-flow fan suitable for ducted applications which has guide vanes before or after the impeller, or both
3.6.2.6
tube axial fan
axial-flow fan without guide vanes, suitable for ducted applications
