Industrial Boiler ID Forced Ventilating Carbon Steel Heavy Duty Blower Fan
Introduction
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.
This Blower Fan can use different speeds to meet the requirements of various dust collectors in the same tonnage boiler, combined redundant fan series and machine number.

Advantages and Features
1. 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.
2. For the materials of impeller and main shaft, for different working conditions and working speed, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature resistant high-strength alloy steel, make the impeller and main shaft to maintain reliable strength at high temperatures.
3. For dust-containing gas, we can meet various working conditions from a small amount of dust to a very large dust content. After special treatment, the surface hardness of the blade can reach HRC60~70, which can extend the life of the impeller by more than 3 times.
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.
