Maintain Static Pressure with VFD for Air Flow Control
Using a variable frequency drive or VFD for air flow control on your industrial fan can increase efficiency and save on energy costs over time. That’s because it gives you a high degree of control while keeping the airstream clear, thus avoiding static pressure losses that inevitably reduce efficiency.
What Fan Shaft Seals Are, What They’re Made of, and Why You Might Need One
There are many industrial centrifugal fan and blower applications that require a shaft seal, including various pollution control, dryer, food and dairy, process cooling, and process heating applications.
Flexible Connectors Protect Your Industrial Fan and Ductwork
Flexible Connectors, or flex connectors, are very effective for protecting the fan wheel and ductwork, and they can also be a highly cost-effective alternative to costly design adjustments during installation.
How to Ensure Gas-Tight Fans for Industrial Processing
When your industrial process application moves toxic or hazardous gas, you need to ensure gas-tight fans so that there is no leakage.
VFD Motor Control for Overspeeding Industrial Fans
Once upon a time, direct-drive industrial fans could only go one speed. With the invention of the Variable Frequency Drive (VFD), industrial manufacturers gained a great degree of control and the ability to overspeed the fan for optimal operation in the application through which it is moving process air.
What is Industrial Fan Noise Directivity?
Industrial fan noise directivity is an indication of how the fan surroundings contribute to the sound level in the field. It is a small but important factor in specifying the right accessories, insulation, housing, and enclosures for noise reduction in your application.
Careful Where You Put Your Insulation
Fan bearing protection is always a high priority, especially with high-temperature fans. That’s because most high-temperature fan failures happen at the inboard bearing. But why? What’s special about that spot? To understand that, you need to understand some nuances of high-temperature fan design and common mistakes made during installation.
Selecting the Right Coating for Insulated High-Temperature Fans
It’s common to apply an industrial coating on the external airstream to make a fan more resistant to heat, fire, particles, etc. and to protect it from corrosion. But there’s more to it than slapping on a coat of paint. There are special considerations for high-temperature fan coating, particularly when you add insulation to the mix. The choices are based entirely on the fan material of construction, namely what kind of steel is used.
Questions About How to Get a Blower Quote
The question about how to get a quote for an industrial blower comes up more often than you might think. The first trick is to also search for how to get a quote for an industrial fan. Same product, different function. A blower is just a forced draft fan that sucks air in to push it through the system instead of induced draft pulling it through the system. See “related content” below to find more details and insights on that nuance.
Can Industrial Fans Catch Fire?
Industrial fan fires are unlikely, but they can create sparks that can cause fires if you’re not careful. What causes sparks in industrial fans? The answer to that question is moving parts and ferrous materials.
Determining the Right Industrial Fan Type
Which industrial fan type do you need in your process to achieve both optimal static efficiency and reliable operation? Considerations include what the fan is processing from clean air to mild particulate to highly abrasive materials, as well as volume and static pressure. Once you know those variables, you can make the fan static efficiency calculation to select the right fan.
Surgeless Fan Design for Vibration Protection Under Pressure
If you’ve ever seen, heard or felt a pressurized industrial fan pulsing, you’ve probably also seen how damaging the resulting vibrations can be. Surgeless fan design moderates volume to avoid that costly scenario.
How to Control Fan Speed
Controlling fan speed for optimal efficiency and performance is as easy as having the right equipment and making a few simple calculations. The ability to control fan speed rests on your motor drive. On direct-driven fan applications, the most common way to change speeds is with a variable frequency drive (VFD). On belt-driven fan applications, a VFD is also useful for simple speed changes. In the absence of a VFD, simple sheave ratio modifications should do the trick. And of course, you need to know the input frequency of the motor and a few simple ratios.
