While HVAC is the majority of our business, we also service niche markets such as agriculture, where we filter swine barns from deadly viruses, power generation, where we supply filters for gas turbines, and paint spray booths, where our products ensure consistent airflow in industrial painting processes. CLARCOR Air sells its products through a variety of channels under the brand names Airguard®, ATI and Purolator™.
