This ID Fan was built for a waste treatment plant and offers strong performance with minimal energy costs. The backward curved impeller can move high volumes of air at high static pressures with high static efficiencies. Installed in 2017, the plant manager boasted that “this fan has been running 24/7 since 2017 and I have not had one single issue.” This fan is the M1 Abrams of industrial fans!
Application: Induced Draft
This installation features a high-pressure ID fan design with a shrouded and oversized impeller for an industrial dryer.
Cargo Ship Application
We designed this induced draft (ID) fan to control emissions from cargo ships while in port.
We custom-designed this high-pressure radial induced draft fan for a scrubber application, with alloy 2205 airstream construction, custom purge air shaft seals, pie-split housing, and an integral inlet box. Configured as a center-hung Arrangement 7 fan, a flexible coupling is used to connect the fan shaft to the motor shaft, and the entire fan assembly is mounted on a unitary base. The application required a severe duty motor rated for use with a Variable Frequency Drive (VFD).
We built this induced draft radial tipped fan for a wet scrubber with a saturated airstream. This application called for an abrasion-resistant wheel and housing with scroll liners and a flexible direct coupled drive. The heavy-duty self-cleaning Radial Tipped Fan delivers process control, stability, and high static efficiency while resisting material buildup on the wheel and impeller.
Updated Application Page, Lots of Examples
People sometimes think that if they already looked at a website, they’ve seen it all. No need to return, right? Not the case, at least not for us. We’re constantly updating, enhancing, and adding to it as we watch to see how people are navigating and hear the questions they’re asking us. One of the important things we did recently was to expand our application pages. This post highlights induced draft fan (ID fans) applications.
Comparing Forced Draft Versus Induced Draft
When comparing forced draft versus induced draft industrial fans, the primary difference boils down to push versus pull. Forced-draft fans focus the pressure and volume at the outlet of the fan to push air through a system, creating positive air pressure. Industrial induced draft fans operate by focusing the pressure and volume at the inlet of the fan to pull air through a system.
AirPro built the following fan for a Wisconsin company that dries potatoes for use in animal feed. The exhaust fan is installed at the end of the drying process. A gradual build-up of particulate on the wheel resulted in excessive fan vibration levels. AirPro field service technicians were hired to balance the fan, restoring it to smooth operation.
September’s story involves the Cheese & Whey industry. AirPro built four fans for a northeastern dairy processing facility. All fans, installed on a whey production system, were required to pass USDA food-safety inspection. The pictured fan, processing the hot air at the outlet of the dryer, included 304 Stainless Steel airstream parts (APIC).
