Fan inlet boxes help manage airflow into the fan, reduce turbulence, and can support transitions or directional changes in ductwork. Why use an inlet box on a fan?

Imagine you have a regular light switch and a dimmer switch for a light bulb. A regular switch only has “on” and “off,” while a dimmer lets you control how bright the light is. A VFD is like a dimmer switch for a fan motor – it lets you control the fan’s speed. Changing the fan’s speed with a VFD also changes the motor’s horsepower (its ability to do work) and torque (its turning power). Let’s break it down for centrifugal fans (the most common type).
An evasé (eee-va-say) is a critical component in industrial fan systems that significantly enhances performance and efficiency. Installed on the fan outlet, it helps improve airflow by providing a natural path for the gas to expand. The evasé connects to the fan outlet at the smaller flange side and gradually expands outward. While the outer edge of the evasé expands at a consistent rate, the inner edge expands more significantly, resulting in a much larger flange at the opposite end.
5 Steps to Find and Fix Industrial Fan Performance Problems
Troubleshooting and addressing fan performance issues can feel overwhelming, but with the five steps outlined below and the help of a trusted application engineer either remotely or on-site, you can find the solutions you need for your operations.
