Retrofit Emission Control Device (RECD)
Pollution-control devices you add to your generator or boiler to clean up the exhaust by capturing or destroying Particulate Matter (PM) along with other harmful gases including carbon monoxide, hydrocarbons, and nitrogen oxides before they escape into the air.
