2.3. Fan section
Depending on the required air flow and static pressure,
plug type fans or double inlet centrifugal fans with belt
drive are used in KLASIK series units. Fans are ba-
lanced statically and dynamically, based on ISO 1940
standard and correspond to class G2.5/6,3 (at maxi-
mum revs). Thus, even at maximum fan speed, vibra-
tion is minimal and is within all requirements.
Plug fans with EC motor
Highly efficient in all operating areas, EC motors are
available in all types of KLASIK units and correspond
to the IE4 premium efficiency level. High efficiency is
determined by low energy consumption, high efficien-
cy factor and the best values of the SFP factor. By us-
ing EC fans in Klasik units the following advantages
are achieved:
• extremely high efficiency up to 92%;
• valuable energy saving up to 30% comparing with
AC in some applications;
• integrated motor controller, no need for a frequency
converter;
• very smooth and silent operation;
• long-life;
• compact construction.
Plug fans with AC motor
Main advantages:
• high efficiency,
• smoothly adjustable productivity,
• good acoustic characteristics,
• durability.
The laminar stream after the fan wheel allows to
lower losses of pressure in a network; there is an op-
portunity to connect the device for measurement of a
stream of air.
Fans with backward curved
blades
Fans with forward curved
blades
The fan is connected to the casing by frame with vi-
broizolators. AC three-phase fan motors (400 V, 50 Hz)
are controlled by frequency converters.
Class of safety IP55 on IEC 34-5, windings of mo-
tors has isolation of a category “F”. Working tempera-
ture up to 40°C.
Double-inlet centrifugal fans with belt drive and with
backward curved blades feature particularly high ope-
rational stability, ensure high pressure, and their effi-
ciency ratio is 85%.
Fans with forward curved blades running at low speed,
have a low noise level and the efficiency to 70%.
