Centrifugal fans consist of the following main assemblies: Frame, housing, impeller and
drive motor. They are delivered with direct drive (impeller on motor shaft) (except for the type
HF R …-48 R), as well as with belt drive (transmission motor-belt-impeller shaft).
The housings of the series HF R …-15 / 17 D R are sintered with polyethylene (PEs. RAL7036)
as standard. The housings of the other series are manufactured in self-supporting welded cons-
truction with dierent thermoplastics adapted to the particular conditions of use. They have a
housing cap on the inlet side, which allows the mounting / dismounting of the impeller after
demounting. For the production series RV 45 and RV 63 optionally also moulded casings made
from PVC and PPs are used. These consist of two shells in which the impellers are laid before
welding. Demounting of the impellers is not possible.
The housing is performed with a splinter protection, has on its deepest point (lateral) condensate drain drillings and it can be delivered with revision opening if requested.
The impeller is statically and dynamically balanced (min. quality class G 6.3 acc. to DIN ISO
21940-11). The vibration limits correspond to the ISO 14964 standard. Depending on the speed
and other procedural parameters, various special materials are used as impeller materials in
addition to thermoplastic. Main dierentiating factor of these series are the dierent bladings of
the impellers and the housing construction.
On the type label are registered the maximum impeller r.p.m.s. For increasing the impeller
r.p.m., previous consultation of the manufacturer is indispensable.
For fans which are appropriated for the use in Ex-zone 1 the housing and the impeller are made
of electrical conductive thermoplastics. The standard thermoplastic plastic fan is not equipped
with shaft sealing.
The HF R ...- 13 D / R DS2 / DS3 series has a Kera seal as standard grown.
The exhaust uid is aspirated axially by the rotating impeller and transported radially to the
outlet in the helicoidal housing. The applied energy is converted into mass ow and pressure
increase of the exhaust uid in the impeller.

2.2 Correct use for the intended application and eld of application
The fans are suitable for exhausting aggressive, dust-free, low-aerosol gases and clean air.
Explosive atmosphere can be exhausted only using fans designed specially for this application.
The permissible gas temperatures for the most frequently used plastics materials are generally
with PVC: 0 °C bis 50 °C,
with PE, PE-FR (PEs) -20 °C to 60 °C,
with PP, PP-FR (PPs): 0 °C to 70 °C,
and with PVDF: -10 °C to 100 °C.
These temperatures must not be exceeded.
Depending on gas composition and impeller speed, these temperature ranges must be check
and restricted, if necessary. With particularly aggressive media, the reductions must be checked
and determined individually in each case. The max. ambient temperature is 40 °C.
Sucient cooling can be ensured regardless of the volume ow, in accordance with the
above-mentioned conditions.
The fan was developed, designed and built exclusively for industrial and commercial use. Using
the fan for domestic purposes is excluded.

Installation inside the explosion-hazarded area:
Installation inside the explosion-hazarded area is not permissible,
unless the fan is provided explicitly for this purpose (see type label
Chapter 4.2).
If the fan for an installation with an open inlet or outlet or is provided
for an inlet-side duct connection as part of a larger installation, the
operator is obligated to prevent the penetration of foreign bodies that
can cause ignition according to DIN EN 14 986, point 4.22.
Repair and maintenance works of explosion-proof fans may only be
performed by qualied persons in the explosion protection by
using original spare parts.
If the fan has an open inlet and / or outlet (Type A, B, C according to
ISO 13349), the fan must have the same category inside and outside.
Types of connection
Residual risks
Although the fans have been constructed according to the newest
technology as well as to the security rules and they are monitored by
quality assurance (QA) system, there remains a residual risk due to
the possible rupture of the impeller. This happens especially, when
the conditions of use have not been complied. Therefore it is necessary to pay attention on technically perfect conditions and on the right
case of application. The environment of the fans has to be secured
in such a way, that in case of a damage, neither persons nor objects
get harmed.
11
These assemblies are intended exclusively for the above purpose.
Using the assemblies for dierent purposes than described above,
or modifying them without written consent of the manufacturer are
considered as non-compliant with the intended application. The manufacturer cannot be held responsible for damage resulting from such
use. The risk is borne exclusively by the user. The fan may be started
only after checking that all safety devices are operable and that the
system in which this fan is installed complies with the EU directives.
The correct use for the intended application also implies compliance with the instructions given
in the manufacturer operating manual and with the conditions for maintenance and repair.
The plastic fans are not covered by the „Regulation No 327/2011 of the European Commission
about the implementation of Directive 2009/125/EC (ErP Directive)“ because they are intended
for the extraction of highly corrosive media.

The materials/uids for the correct use of the fan in compliance with
the intended application are procured and applied by the manufacturer. The user is responsible exclusively for correct handling of these
materials/uids and the related hazards. Information on hazards and
disposal must be provided by the user. Follow the rules given in the
manufacturer‘s safety data sheets for materials and uids.
