At OTR Filters we understand that filtration is the foundation of any engine, and your engine performs well because it is filtered the right way. An automotive filtration system is critical to the performance and efficiency of your vehicle. From the days of cobbled roads to the superhighways, how we filter things has changed dramatically.
Oil bath filters, developed in the early 20th century, were once the workhorse of automotive filtration. They used an oil reservoir to capture dust and other particulates before reaching the engine. A basic design, oil bath filters were known for their reliability and were found mostly in heavy-duty vehicles. They worked well on the dusty roads of the mid-20th century.
As the automobile changed, so did its filtration needs and the filters needed to fulfill those needs. Paper air filters came along and drastically improved on the old, oily bath filters. From then on, engine air filters became more efficient in filtration and much easier to work with. As time passed and more complex engines were created, meeting the demands of ever-evolving standards, synthetic filters were developed in the late 20th century to accommodate the growing needs of changing technologies.
In the present day, vehicles use sensitive filters to remove contaminants. These filters, which use advanced materials and designs, can effectively remove particulate matter, allowing engines to run smoothly, emit lower emissions, and make less noise.
The transformation from the oil bath filter to high-tech systems shows that innovation is key to providing you with the best automotive filtration. And that is our mission at OTR Filters: the latest technology to keep your engine performing its best.
