VMEVO – 6, 7, 8, 10, 12
Local ventilation fans: VEMEVO-6 (6/1), VEMEVO-7 (7/1), VMEVO-8 (8/1), VMEVO-10 (10/1), VMEVO-12 (12/1)
-The fan is built on the basis of a new high-pressure aerodynamic scheme, specially created for optimal operation with ventilation ducts; – Lightweight impeller of the fan, which increases the reliability and durability of the motor bearings, is made of high-strength carbon steels with increased resistance to mechanical stress; -If it is necessary to increase the air supply to the face and in cases of extra-long workings, the fan design provides for the possibility of sequential sectioning of two or more units into a single unit; -Special anti-tearing device prevents the occurrence of surge operation modes and expands the working area of the fan; – In places of possible frictional friction, brass protectors are installed that exclude sparking; – At the request of the consumer, the fans are equipped with devices to reduce noise.
