CARB verifies Donaldson filter for 1994-2006 diesel engines

Donaldson Co., a manufacturer of filter systems and replacement parts, has announced that the California Environmental Protection Agency’s Air Resources Board has verified the company’s diesel particulate matter low-temperature filter (LTF) muffler for 1994-2006 model year non-EGR diesel engines used in on-road applications operating on ultra-low-sulfur diesel. With the CARB verification, this product is acknowledged to provide particulate matter (PM) reductions by at least 85 percent, qualifying it as a CARB Level 3 device.

“Donaldson is proud to receive this verification from CARB,” says Fred Schmidt, director of sales for Minneapolis-based Donaldson’s emissions group. “The Level 3 verification of the LTF muffler complements our retrofit product line, providing our customers a wider selection of products to meet the CARB diesel reduction requirements. The Donaldson LTF muffler, used with or without the patented Spiracle crankcase filter system, utilizes a durable, patent-pending design to effectively reduce particulate matter emissions.”

The LTF muffler basic design is a flow-through filter followed by a wall flow diesel particulate filter and a backpressure monitor. The Spiracle crankcase filtration system can be included to eliminate emissions from the crankcase and reduce in-cabin emissions. Donaldson recommends the LTF muffler for light-duty operating conditions with low-exhaust temperatures.

CARB’s Diesel Risk Reduction Plan requires that all existing vehicles and engines be evaluated and, wherever technically feasible and cost-effective, retrofitted, repowered, refueled or replaced to reduce diesel PM emissions. This product also meets the requirements of the EPA’s Voluntary Retrofit Program.
