Coupling Driving High Temperature Cooling Induced Draft Blower Fan
Introduction
The Coupling Driving High Temperature Cooling Induced Draft Blower Fan
has a large flow rate and moderate pressure.
This fan is designed for the purpose of using industrial boiler to
work in the high-efficiency area and achieve the energy-saving
target.
The fan is suitable for equipped with economizer (heater) and smoke
and dust removal device.
Coupling Driving High Temperature Cooling Induced Draft Blower Fan is a high-efficiency energy-saving product jointly designed by the
national fan industry and organized by the national wind power
industry and the Ministry of Machinery Industry.
It has the characteristics of high efficiency, low noise, flat
performance curve and wide efficient area.
Industrial boilers of 5 ~ 35 tons/hour can be used, those with
similar intake conditions and suitable performance can be used, but
the maximum temperature shall not more than250°C.
Before the induced draft fan, dust removal device with a dust
removal efficiency of no less than 85% must be installed to reduce
the dust content of the smoke entering the fan.
It can not only reduce the pollution of the smoke on the
environment, but also reduce the wear of the smoke on the fan,
which is conducive to prolonging the life of the fan.

Advantages and Features
1.The fan can output higher gas pressure, and can provide more gas
flow at the same time, low noise.
2. In the case of using the common base, the installation is very
simple and basically does not require the support of professional
technicians.
3. The motor shaft is elastically connected with the drive shaft.
It is not necessary to tighten the belt or replace the belt
frequently, and the maintenance workload is small.
4. The fan system running at normal temperature with an impeller
diameter of less than 1400 mm does not require additional
configuration of bearing cooling device, which reduces the user's
investment and maintenance workload.
5. When the airflow resistance is increased, the motor load will be
automatically reduced and the motor will not be burnt.
6.The fan is made of high quality carbon steel, and can also use
stainless steel or other metal materials according to customer
requirements.
7. Running test and vibration value detection after the production
is completed, the fan operation is reliable.
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.
After sales service, we will offer 12 months’ repairing service,
and provide lifelong follow-up services. Besides, our engineers are
available for going abroad to offer the repairing service.
3. Does your company have qualifications?
Answers: SIMO Blower has obtained ISO 9001-2008, CE, BV
