BASIC CHARACTERISTICS
The design of fans is presented on fig.1 for BB
100 and fig.2 for BB 100 A.The designation of
the fans, their parameters, appearance, the
overall and connecting size are given in table 1
for BB 100 and table 2 for BB 100 A. The fans
are intended for connection to ac network with
voltage of 220–240 V and frequency of 50 Hz.
The fans are intended for use in premises with
air temperature within the range from 0°C to
+45°C. The fans do not create noise for radio,
TV and video equipments. Service life is not less
than 10 years.
STORAGE RULES
Store the fans in the manufacturer packaging
in an aired room at temperature from +5°C to
+40°C and relative air humidity no more than
80 % (at t=25°C). Presence of steams, acids,
alkalis and other aggressive impurities in air is
not allowed.
MAINTENANCE
The fans maintenance should be carried out
only after their disconnection from the network.
The maintenance refers to periodic clearing of
the fans surfaces of dust and dirt. Carry out
the cleaning with a soft cloth moistened in a
soap solution, then wipe the surfaces dry. The
impeller blades demand a careful clearing every
6 months. For this purpose, you should remove
the impeller from the motor shaft (keeping the
plug). Wash up the blades with solution water
and cleaning agent. Avoid ingress of liquids on
the electromotor.
