We built this forced-draft, high-pressure blower with a surgeless design on a unitary base for a milling operation processing corn in an ethanol plant. The application called for an inlet elbow, functioning as an inlet box to address the space constraints and minimize the impact on fan performance. To eliminate catch points for material, external welds are continuous and ground smooth.
Application: Forced Draft
Updated Application Page on FD Fans
FD fans create positive air pressure and volume at the outlet to push air through the system. For reference, fans are either forced or induced draft. Induced draft fan (ID fan) applications focus pressure at the inlet. You can read more on ID fans here.
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.
Get Warmed Up: FD Fans for Your Industrial Burner Workout
You wouldn’t run a 5K without warming up a little first. Your boiler system doesn’t like a cold start either. Industrial boiler systems run most efficiently when the ambient air is preheated via industrial burners using Forced Draft Fans (FD Fans).
AirPro received the OEM order for four tempering blowers built for a glass manufacturer here in our home state of Wisconsin. The fans are installed on the back end of the glass oven, providing supply air for the tempering process.
