The necessity of such replacements is explained. The
frequency of replacements depends on the ambient
dustiness and the method of the blower set use.
4. Acquainting the operators with the correct

RESSURE DEVICE
According to the European Parliament and Council’s
Directive 97/23/ES, which stipulate the technical
requirements for pressure devices, the discharge silencer
of the blower set is classified as a pipeline part.
The device is equipped with safety valves:
1) Designed by LUTOS; the conformity of the valves has
been assessed in accordance with the ES procedure for
type testing. According to Section 3, Appendix No. 3 of
the Government Decree, Number E-32-00220-02, the
products are marked with the CE 1015 symbol.
Type testing was executed by Brno-based Strojírenský
zkušební ústav s.p.
2. Purchased from the GMBH HEROSE company; the
conformity of these valves has been assessed in
accordance with the European Parliament and Council’s
Directive 97/23/ES. The products are marked with the CE
0045 symbol.
Type testing was executed by TÜV CERT-
Zertifizierungsstell für Druckgeräte der TÜV NORD
GRUPPE.

ON-STANDARD BLOWER DRIVE
(APPLIES ONLY IF A SEPARATE BLOWER IS PURCHASED)
If an electric motor is not used as the blower drive (e.g., a
combustion engine is used), the chosen design must
prevent the output blower shaft from loading with a force
higher than permissible. It must also protect the shaft
against the vibrations transferred from the driving motor.
For example, a direct connection with a propeller shaft is
unsuitable.
Design recommendations:
a) Both the blower and the combustion engine must be on
the same frame. Only such a frame can be flexibly
mounted. The engine vibrations must be within the
acceptable limits.
b) A supporting bearing in a bearing block that will absorb
the vibrations and forces must be installed between the
blower and the combustion engine.
c) A flexible coupling (e.g., a PERIFLEX coupling) must
connect the bearing with the blower. The type of
connection between the plain-collar bearing and the engine
could be similar; nonetheless, it is not absolutely
necessary.

Another possible solution is using a non-standard blower equipped with an auxiliary plain-collar bearing of the output shaft in the cover.
