V-Belt Driven Medium Pressure Backward Cooling Centrifugal Flow Fan
Introduction
The 5-12 series centrifugal fan air flow is an enhanced version of the 5-11 series medium pressure
centrifugal fan.
It has a larger output flow than the 5-11 series. It is also used
to transport a variety of common gases and hard materials in the
industrial field, the application object is exactly the same as
5-11 series fan.
The impeller is subjected to a high standard of dynamic balance
correction to ensure stable operation of the fan.
After the production is completed, all products are tested for
running and vibration values for reliable operation.

Advantages and Features
1. It is boiler induced draft fan with a total internal pressure
efficiency of 90.5% specially designed to be suitable for various
coal quality and equipped with a smoke-and-dust removal device
(1~20 tons/hour).
2. The adjustment door can be used to flexibly adjust the pressure
and flow of the fan during operation. It can also be equipped with
a variable frequency motor to adjust the pressure and flow of the
fan by changing the speed.
3. The bearing housing uses a labyrinth mechanical seal, a unique
Leak proof oil design inside, a vent hole at the top, and a sealant
on the joint, completely eliminating the possibility of oil leakage
in the bearing housing.
FAQ
1. What parameters need to be provided when you design the
industrial centrifugal fans?
Answers: Air flow, total pressure or static pressure, inlet
temperature, local voltage and frequency, Altitude etc.
If there is flammable and explosive gas, or big dust loading in the
medium, please also inform the designer.
2. How about your company’s pre-sales service and after-sales
service?
Answers: Before our cooperation, we have the professional technical
team to help you make the technical solution according to your
working condition, to make sure the centrifugal fan efficiency
operation.
