Recirculating the air from your dust collector: Benefits, cautions, and equipment selection advice
Are you sending your plant air out the stack after it's been filtered by your dust collection system? If so, you not only have to spend a lot of time dealing with EPA regulations, but you're probably sending energy dollars up the stack along with your cleaned air. This article explains how to overcome these problems by recirculating that cleaned air back into your plant. Sections cover recirculation basics and provide advice on designing a recirculating dust collection system.
Whether you use a dust collection system to control your plant's indoor air quality, keep your equipment clean, or recover high-value process dusts, chances are the system exhausts the cleaned air outdoors. But in many cases you can reduce regulatory paperwork, save a substantial amount of energy, and even become a better neighbor by recirculating the cleaned air back into your plant.
