A Catalyst is used in an exhaust unit to facilitate the conversion of harmful pollutants in the exhaust gases into less harmful substances before they are released into the environment. The primary purpose of an exhaust catalyst is to reduce the levels of nitrogen oxides (NOx), carbon monoxide (CO), and unburned hydrocarbons (HC) emitted by internal combustion engines.Attributes:• Designed to convert harmful pollutants into less harmful compounds• Manufactured to precise specifications and are built for durability and reliabilityApplications:A Catalyst helps to significantly reduce the emission of harmful pollutants from the machine's exhaust.
