Paccar Parts describes the Engine Control Systems Purifilter as an aftermarket passively regenerating diesel particulate filter approved by the California Air Resources Board for installation and use in a wide variety of Class 8 truck models. Paccar Parts distributes the device exclusively through Kenworth and Peterbilt dealers in the United States and Canada.
Engine Control Systems says the Purifilter – which features a silicon carbide filter to facilitate exceptional regeneration, performance and durability – is approved for use with a wide variety of model year 1993-2006 heavy-duty trucks in a number of on-highway applications, regardless of manufacturer. The Purifilter also has received conditional verification from CARB for use with certain 1996-2008 off-road diesel engines that are rated at least 50 hp, but no more than 750 hp; the verification covers engines certified for offroad use on equipment such as trucks, loaders, dozers and skidders.
Each Purifilter model is available in five different inlet/outlet configurations with either standard stamped flanges or optional machined flanges. The 100 percent stainless-steel modular design is designed to allow for 360-degree rotation of the muffler inlet and outlet sections to provide the greatest range of fit. The dimensions of a Purifilter vary depending on application; the smallest filter weighs about 75 pounds and is 10 inches in diameter (11 5/8-inch diameter at the mating flanges) and measures 38 inches in length (including inlet and outlet tubes). The largest filter weighs about 125 pounds and is 13 inches in diameter (15 inches at the mating flanges) and measures 43 inches in length.
Engine Control Systems says it also manufactures and supplies Kenworth and Peterbilt dealers a wide range of mounting and installation hardware and customized parts; with both horizontal and vertical mounting options, a Purifilter can be made to fit in almost any vehicle. A backpressure monitor and logger system, included with the Purifilter, is designed to record vehicle duty cycle information for up to two years, and allow truck operators to monitor the filter’s condition continually. The filter requires ash removal at periodic intervals based on the truck’s duty cycle.
