Industrial induced draft fans (ID Fans) operate by focusing the pressure and volume at the inlet of the fan to pull air through a system. This focus creates negative air pressure. ID fans often work with FD fans to maintain an efficient and steady air pressure. The flow is controlled using VFDs, dampers, & other accessories. The induced draft often results in high temperatures and air particulate which can rapidly wear down a poorly constructed fan. AirPro builds heavy-duty, high-temp industrial fans for induced draft applications.
