MINNEAPOLIS, MN – June 17, 2008 – Donaldson Company (NYSE:DCI), a leading, worldwide manufacturer of filtration systems and parts, introduces the Pulse Jet Air Cleaning (PJAC™) Ultra™ self-cleaning air cleaner designed for maximum engine protection, minimized filter element servicing, improved fuel economy and vehicle engine power. This improved air cleaner is ideal for military vehicles and applications operating in demanding environmental conditions.
The Donaldson PJAC is a patented, self-cleaning air filter that cleans filter elements with short duration pulses of compressed air. This two-stage air filtration technology ensures the best engine protection and a longer life cycle due to minimized filtration servicing with no scavenge required. Designed with Donaldson UltraWeb® Nanofiber Filtration Technology, the PJAC Ultra air cleaner provides the highest level of efficiency – 99.997+% – and has a filter life of greater than 200 hours when tested per MIL-PRF-62048. Manufactured with a durable, corrosion-resistant coated metal housing, the new air cleaner is built with the Donaldson Vacuator™ Valve which automatically rids the system of collected dust. This field tested, mature filtration technology is scalable to meet customer space requirements and requires no tools for servicing.
“The PJAC Ultra represents a significant breakthrough in air filtration technology,” said Gary Gillingham, director of engineering for the Defense Group at Donaldson Company. “The PJAC Ultra eliminates the need for frequent filter servicing in harsh environments. Donaldson has been able to achieve these advantages in a product that can cost less than a conventional scavenged heavy duty filtration system.”
Lab and field tests have demonstrated that filter service intervals are reduced by more than ten times compared to conventional air cleaners. With its UltraWeb nanofiber media the PJAC Ultra air cleaner also provides a 10-100 times improvement in engine protection. The Donaldson PJAC Ultra is a suitable filtration solution for a variety of vehicles and applications, such as HMMWV, JLTV, tactical and armored combat vehicles, retrofit opportunities and commercial vehicles.
