The low and medium pressure centrifugal fans are designed to complete industrial ventilation systems and equipment for production processes.
Low and medium pressure centrifugal fans transport mixtures and gases of mechanical impurity with a maximum temperature of 323.16 ° K (50 ° C). They can be operated in premises of classes P-I, P-II, P-IIa, P-III, according to PSTN - 94.
Centrifugal low and medium pressure fans provide flow rates from 400 to 100,000 m3 / h and pressures up to 3000 Pa.
Centrifugal low and medium pressure fans are manufactured in two types:
- VNSH with V-belt, size 2.5; 4; 6,3; 8; 9.5; 14;
- EVNN with impeller mounted on the motor shaft, size 2.5; 4; 6,3; 8.
Centrifugal fans for low and medium pressure are equipped with motors and starting equipment with protection degree IP 54, and for fans type VNCN and with belt pulleys, belts and tensioners for the motor.
