Portable Diesel Filtration

These portable units are a cost-effective way to filter diesel and biodiesel in storage or transport. Filter Carts are fully portable and self-contained. They are easily moved at the job site by one person using the built-in wheels and handle. Filter carts can polish, clean up, and recycle old or contaminated fuel. They can also be used in preventative maintenance practices to keep fuel tanks clean.

Desiccant Breathers

Set the standard for contamination control. Get breathers with state-of-the-art features that reduce particulate and moisture contamination, keeping your equipment and fluids lasting longer. The innovative breather line integrates check valve technology in a desiccant breather and offers replacement cartridges to reduce maintenance costs significantly. The clear view 360-degree design makes it easy to inspect the color-changing silica gel’s saturation from a distance. The inert silica gel turns from gold to dark green to visually indicate moisture adsorption and confirm the breather is getting the job done.
