SIGNING
AXIAL FANS
The marking of the fan indicates its type, motor power, number of poles, number of blades and direction of flow.
In the case of two-speed motors, the markings for the first and second gear and for the poles are separated by a dot.
The markings for explosion-proof fans include information on motor speed and temperature class.
For diameters of 1400-200 K-type fans, the blade profile (blade type) is indicated in brackets next to the number of blades.
SE fans have their own simplified marking.
