FOR IMMEDIATE RELEASE
DONALDSON OFFERS A NEW TWO-STAGE DIESEL PARTICULATE FILTER (DPF) MUFFLER CLEANING SYSTEM
An Efficient and Cost-Effective Cleaning Solution for Truck Maintenance Facilities
MINNEAPOLIS, MN – January 24, 2007 – Compliance with the 2007 heavy-duty diesel engine emissions regulations has increased the use of Diesel Particulate Filter (DPF) mufflers on on-highway trucks. DPFs capture the ash and soot generated during the diesel combustion cycle and continuously combust the soot leaving the ash to be dealt with. Consequently, these DPFs will need to be cleaned periodically through their life cycle. Truck maintenance facilities can now purchase an efficient and cost-effective DPF cleaning system from Donaldson Company (NYSE:DCI), a leading manufacturer of filter systems and replacement parts.
The Donaldson Pulse Cleaner is a self-contained system which dislodges diesel ash and soot from the DPF. The removed ash and soot are captured in a serviceable filter located in the lower portion of the system's cabinet for easy removal. The average cleaning cycle is 15 minutes or less, depending on the level of contamination.
For extremely plugged filters which require a more intense cleaning process, Donaldson offers the DPF Thermal Regenerator, a specially-designed unit that removes hydrocarbons and unburned soot through a timed heating and cooling cycle. Donaldson's two-stage DPF cleaning system simplifies the routine cleaning, making it ideal for maintenance facilities responsible for servicing trucks equipped with diesel particulate filters.
For more information, visit the company's Emissions + Exhaust website at www.donaldsonexhaust.com or contact Donaldson toll free at (866) 675-2847.
