HG785 Alloyed Steel Single Suction Ventilation Centrifugal Flow Fan
Introduction
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).
This type of fan is currently used in the boiler industry. The air volume of the induced draft fan and the difference in wind pressure are relatively large, in order to adapt to the above situation, considering the practicability of the fan, in addition to the 20-ton boiler ID fan need large power coupling direct transmission, the other uses the triangular belt type transmission.

Advantages and Features
1. It is capable of outputting a higher outlet pressure while providing more gas flow with lower noise. Stable operation at higher media temperatures.
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 cooling method selects a low-cost water-cooling method or an oil-cooling method with better heat dissipation depending on the gas temperature and the conditions of the use environment. For extremely high temperature operating conditions, an electronic cooler can also be added to absolutely protect the reliable operation of the fan system.
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 certifications and so on.
