Selective Catalytic Reduction (SCR) Filter Elements

United Filtration Systems borosilicate microfiber 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. The advantage of our element is the fact that the AW series will fit standard existing filter housings already in service. No new installation is required.
