K GradeElements are specified for particulate removal where corrosive gases and liquids are to be filtered as they have excellent chemical resistance. They are also used when highly reactive gases are being analyzed since they exhibit very low levels of adsorption.
ET GradeElements are hydrocarbon-free filters developed to remove particulate for automotive emission testing up to 400ºF.
RPT GradeElements are constructed of a proprietary blend of microfiber glass and resin binders which virtually eliminate initial hydrocarbon content and fiber migration. This feature provides fast initial response times for emission analysis. These elements have the ability to function up to 650°F (342°C).
S GradeElements are completely inorganic and are used to filter particulate at temperatures from 300°F to 900°F.
S21-R GradeThe S21-R Type are used in diesel emission applications.

SCR Filter Elements (Acid Washed)Acid Washed (AW) series of elements capture the excess ammonia that is introduced into the emission stream. This scrubbing is done by a chemical bond between the ammonia (NH3) and the acid washed (Phosphoric) filter elements, thus protecting sensitive equipment. These are commonly referred to as Selective Catalytic Reduction (SCR) Filter Elements.
