MINNEAPOLIS, Minn. — A free video describing the benefits of Donaldson’s Diesel Oxidation Catalyst (DOC) muffler and Spiracle closed crankcase ventilation filtration system is now available from Donaldson Company Inc.

The DOC muffler/Spiracle filtration package provides an effective control system to reduce emissions of particulate matter without sacrificing engine performance. In addition, it enables users of older medium- and heavy-duty vehicles to retrofit their engines and meet impending U.S. and local regulations to reduce allowable emissions for new and in-use diesel engines.

The video is a copy of a recently released segment of American Environmental Review, a series often aired on public television stations throughout the country. The program focuses on:

* Research findings that demonstrate the impact of diesel particulate matter emissions on air quality

* The changing requirements for emissions and air standards

* Innovative solutions from Donaldson that significantly reduce particulate matter emissions from diesel engines

* Information about how to meet stricter emissions guidelines without sacrificing reliable older vehicles

Donaldson’s Spiracle filtration retrofit system can be used across a broad spectrum of engines, with the widest range of operating conditions, including medium- and heavy-duty trucks and buses, light vehicles such as pick-up trucks, medium and heavy-duty off-road equipment, and light industrial equipment. The DOC muffler/Spiracle filtration system meets the U.S. Environmental Protection Agency’s (EPA) Voluntary Retrofit Program warranty requirements and has received the California Environmental Protection Agency’s Air Resources Board (ARB) Level 1 verification.
