MINNEAPOLIS (January 27, 2020)—Donaldson Company, Inc. (NYSE: DCI), a leading worldwide manufacturer of filtration products and solutions, today introduced a new vent to help protect vehicle powertrain enclosures from contaminants and pressure stress. Donaldson now offers four powertrain vents (PTV) – the Screw-Fit and three Hose-Fit Powertrain Vents – that bring standardized assembly and long vent life to vehicles operating in harsh conditions. All Donaldson PTVs feature the industry’s first oil-coalescing pre-filter to help maintain airflow.
Powertrain vents help protect a vehicle’s transmission, axles and other components from harsh environments and mediate pressure changes that can stress housing seals and gaskets.
“Powertrain venting is crucial to the performance and reliability of a vehicle, but common vent hoses have been cumbersome to install in a standardized way and tend to clog with lubricants.”
Nathan Malek, general manager of Integrated Venting Solutions for Donaldson
Conventional venting hoses can be up to 3 meters (10-feet) long, while Donaldson vents measure a mere two inches or less in length for faster, standardized assembly across multiple vehicle models. The Hose-Fit Vent fits like a cap over the end of a short vent hose, and the low-profile Screw-Fit Vent screws directly into the powertrain housing.
To address the biggest threat to vehicle venting – a build-up of oil film that reduces venting airflow – Donaldson powertrain vents have a coalescing pre-filter made of proprietary Synteq™ XP media that sheds oil.
“By efficiently capturing oil particles at the coalescing stage, our vents have advanced performance and service life,” said Dustin Waller, research and development project engineer for Integrated Venting Solutions at Donaldson.
The two powertrain vents join Donaldson’s growing automotive venting product line, which includes a Dual-Stage Battery Vent as well as Snap-Fit, Press-Fit, Weld-Fit and Screw-Fit Vents for numerous other vehicle components, from headlights and sensors to fluid reservoirs.
