New Automatic Filter for Engine Testing

Lansing, MI – October 23, 2009 – Sierra’s Automatic Filter Changer is a compact and portable safety and automation tool that should be a part of every emissions test cell.

The Automatic Filter Changer allows the engineer to stay out of the test cell during testing as several tests are done in succession. Our automatic filter changer works seamlessly with the Model BG®-3 particulate partial flow sampling system to fully automate particulate collection to greatly improve testing efficiency and more importantly, testing safety. The system can hold up to 22 (dependent on filter size, 47mm, 70mm, or 90mm) single or double filter cartridges. Sierra will customize the filter changer for 47mm, 70mm or 90mm applications. For example, Sierra has designed the changer to work interchangeably with both 47mm and 70mm.

The system meets all Federal Register requirements and has proven through extensive test at Caterpillar over a 6 month period to be the most rugged and reliable automatic filter changer on the market.
