TURBINE DESCRIPTION
3.1
INTENTED USE AND CONTRAINDICATIONS
3.1.1
INTENTED USE
The side channel turbines described in this manual were designed and built to be used in industrial systems and
are fitted with bi-polar three-phase or monophase asynchronous electric motors according to IEC 34-1.
These turbines are available in mono or double stage and are equipment for the generation of vacuum and
overpressure and the continuous conveying of clean air, air/gas mixes and inert gases whose temperature must
be between 0 and 40°C.
It is possible to power the turbines fitted with three-phase motors via a frequency converter (inverter) in an
operating field between 35 and 70 Hz.
Operating outwith the permitted frequency field can damage the turbine itself and put
the operator in serious danger.
It is the duty of the inverter installer to carry out checks and any necessary controls to respect the immunity and
emission limits established under current regulations.
Any other use is prohibited. The Manufacturer is not liable for any damage to persons and/or property
caused by improper use of the turbine.
3.1.2
CONTRAINDICATIONS
Any use other than that for which the side channel turbine was constructed is to be
considered irregular and can, therefore, cause damage to the turbine and pose serious
danger to the operator.
Below is a series of operations involving improper use of the turbine, which
are not permitted
under any
circumstance.
Do not use the turbine in non-industrial installations unless all necessary precautions and protective measures
have been taken (e.g. protection against contact for child safety);
Do not use the turbine in conditions other than those indicated in the tables shown in point 3.3 of this manual;
Do not use the turbine in an explosive or aggressive atmosphere or in an atmosphere with a high concentration
of dust or oily substances and do not use it to pump explosive, flammable or corrosive gases or gases that form
particles; Using the side channel turbine in these atmospheres and with these types of gases can cause injury,
explosion, fire or seriously damage the turbine;
Do not use the turbine without installing the intake filter and necessary safety devices (vacuum and/or pressure
reducing valve) according to the application it is designed for;
Do not change or transform the turbine, carry out repair or maintenance work of your own initiative. Maintenance
work can only be carried out in compliance with point 6 of this manual.
Do not operate the turbine with the intake and outlet closed;
Only use original spare parts or parts provided by the manufacturer;
Do not use the turbine to pump solid materials, chemicals, powders, solvents or other substances differing from
those permitted. These kinds of materials may damage the unit, limit its performance or reduce its lifespan;
Do not expose the turbine to rain, steam, excessive humidity or direct sunlight;
Do not install the turbine in places subject to possible flooding;
Do not place or store near flammable or combustible materials or substances;
3.2
NOISE EMISSIONS
The side channel turbines described in this manual were designed and built in order to reduce noise level at source.
The sound pressure values indicated in point 3.3 have been read in compliance with directive UNI EN ISO 2151
making the turbine work at 2/3 of the acceptable maximum pressure with intake and outlet conveyed.
The actual sound emission while operating depends, however, on the installation conditions and position of the
turbine on the system.
Special silencers are available on request to reduce the noise level.
