There are many reasons you would want to control the airflow in your industrial fan application. How you do it is based on your fan curve, whether you need to reduce volume, maintain pressure, change the curve based on frequency in hertz to add efficiency, protect your system against surge, or address multiple issues at once.
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.
We’re thrilled to announce our intent, pending permitting, to expand our two factories in Rhinelander, adding production capacity and team members to meet growing demand. The planned plant expansion begins later this year and will increase overall plant square footage by 40 percent across the two facilities.
At AirPro, our manufacturer’s representatives (reps) are our lifeline to mutual customers and vice versa. We depend on them for their application expertise, industry knowledge, and ability to translate customer challenges into solutions working closely with our application engineers. But more than anything, we rely on their deep customer relationships and service mindset. We choose them as carefully as they choose us.
2021 marks the five-year anniversary of AirPro’s Employee Stock Ownership Plan (ESOP). To mark the occasion, we thought we’d get some background from Founder Keith White on his decision to sell the company to his employees. Watch the video above or read on to hear what he had to say.
This week marks a year since communities around the world and here at home began to lock down in the face of the global pandemic. It felt – and still feels – like everything changed in an instant. But in fact, everything did not change. There were many essential businesses including AirPro that kept producing and serving thanks to the dedication of their essential workers.
We are excited to announce the expansion of our Backward Curved models to include fans with wheel diameters below 27 inches. Combustion Air and other Forced Draft applications often require fans designed for low airflows at higher pressures, and we have traditionally supplied our high-pressure blower models for these applications. But our customers started asking us for fans with lower horsepower requirements, and our product development team set out to expand our offerings with more efficient options.
Centrifugal fan troubleshooting is definitely a science. But to application engineers like us, there’s also an art to it. The trick is knowing what to measure and the system effects that can influence those measurements. And it all depends on the specific application. The really short answer to the question of how to troubleshoot a centrifugal fan is to call an application engineer at the fan manufacturer or your manufacturer’s rep. They’ll know exactly where to look. But if you want to take a peek under the hood yourself, here’s a quick overview of where to start, what to measure, what to watch for, and ways to adjust.
We are thrilled to announce that we have named Todd Schaefer, President, Schaefer Industrial Air LLC, as our exclusive representative serving the northern Illinois and northwest Indiana region.
