A-ZBus Emissions Technology

Technologies: A-Z Emissions Solutions is an authorized dealer for the following manufacturers of active and passive Diesel Particulate Filter Systems. Because A-Z Emissions represents multiple manufacturers, we can offer multiple solutions and have a greater ability to meet your custom needs.

Cleaire – Cleaire Advanced Emissions Controls was founded to develop industry leading diesel exhaust clean up systems. The Cleaire Horizon product is recommended for school buses. Horizon is an actively regenerated particulate filter that uses an integrated electric heater to periodically “cook-out” captured diesel particulate, much like a self cleaning oven. The active regeneration technology eliminates any concerns of low exhaust temperature and/or variable duty cycles such as regular route and driver changes.

HUSS – The HUSS LLC MK system is a very robust design incorporating premium materials. The durable HUSS systems are designed for heavy duty on-road and off-road applications. Main applications are: Refuse trucks, construction and mining equipment, industrial trucks, stationary generator sets, and heavy duty on highway vehicles.

Donaldson - Donaldson creates a broad spectrum of filtration products and services to meet the evolving needs of our diverse customers. These filtration solutions span the entire life cycle of a customer’s application, from initial system design through replacement products. Donaldson’s SEF Muffler System is a new semi-active DPF system that is effective on a broad range of vehicle duty cycles and engines. Donaldson’s LNF Muffler is a passive DPF technology that provides the highest tailpipe PM reduction available today making it a popular choice for retrofit programs.

Econix - The Econix DPF-A is an active DPF that uses an advanced metal fiber filter to trap diesel particulate matter (PM) contained in diesel engine exhaust gas. The DPF-A provides sustainable emission reduction without the use of a catalyst and with minimal regeneration down time. (Less than 10 minutes) Independent of vehicle/equipment duty-cycles, the Econix DPF-A’s robust design does not require minimum engine exhaust temperatures for sustainable emission reductions or operations.

ESW - The ESW Group of Companies currently manufactures and markets a diverse line of proprietary catalytic emission conversion, control and support products and technologies for the International Transportation, Construction and Utility markets. . ESW’s ThermaCat filter system is a combined technology comprised of a regeneration component by means of external fuel injection and a passive component by means of a catalytically coated filter substrate. It is intended to operate on vehicles with severe duty cycles, where low exhaust gas temperatures are predominant and traditional passive DPF system would not be suitable.

DCL International - DCL International, known as DCL America Inc. in California, is a supplier of passive off-road filters.  The MINE-X SOOTFILTER® series of DPF’s are CARB verified Level 3 Plus, passively regenerating diesel particulate filter for off-road and stationary diesel applications. The devices are verified by the California Air resources Board (CARB) to reduce emissions of diesel particulate matter by greater than 85%.
