The RoboVent A15 filter is a breakthrough in filter technology. With RMO technology and proprietary media, the Endurex A15 sustains filter life 1.5 to 2 times longer than standard filters. Ideal for dry, dusty particulate, the Endurex A15 filter can be used on many applications. As you can see in the graph, the filter provides superior filtration with low static pressure. The low filter pressure improves collector performance, while the MERV 15 nanofiber media efficiently filters particulate down to 0.1 micron in size.
