Endurex RMO Cartridge Filters

Clean Air Matrix

RoboVent engineers are experts in every category of air filtration and ventilation. The four categories below represent the major options for treating your contaminated air. RoboVent has designed solutions for each of these categories and has manufactured air filtration systems of unrivaled quality.

For more information about these categories, see Indoor Air Quality 101.


Large blowers and air filtration equipment draw contaminated air from the plant (typically at the ceiling level), filter it and return it to the plant. This is a proven solution in plants welding large parts with overhead cranes. It reduces the haze in the air, resulting in a cleaner working environment, with no negative pressure or heat loss.


Air in the immediate area of the welding activity is captured in a hood system, then filtered and returned to the plant. This is the best solution whenever possible. It allows for a more flexible system and removes the smoke directly from the operator's breathing zone. There are many types of source capture, including overhead hoods, crossflow hoods, fume arms and fume guns, some of which work better than others.


Large exhaust fans draw contaminated air from the plant and exhaust it directly into the environment, typically through the roof or walls. This is a traditional method and often results in negative air pressure. Also, it is very difficult to climate-control your plant and the system may not work well in the winter.

Air in the immediate area of the welding activity is captured in a hood, sent through ductwork, and exhausted directly into the environment. This is a lower capital cost alternative to filtration, but tends to result in high operating costs and large, unsightly ducting systems that work less efficiently with modifications. It also results in negative pressure problems.

Whether its ultra-fine dust, metal cutting fumes, or aggressive abrasive particulates, RoboVent Air Filters have you covered.

RoboVent's premium Endurex filter cartridges have been engineered to provide you the very best filtration protection for your plant and employees. Durable and proven, our filter media has been designed for outstanding performance in filtering fumes, smoke, dust, oil haze and other particulates/pollutants created during virtually any manufacturing process.

It's No Longer About Media Quantity. It's About Media Optimization.

Endurex RMO is truly the future in efficient filtration. By widening the pleat spacing in our proprietary filter media and ensuring that the pleats remain apart, we maximize the surface area of media available to dust and fume particles while maintaining the highest level of filtration efficiency. The result is a reduction in static pressure and a superior release of particulate. In short: longer filter life, using less media.


Endurex RMO Filter Design

RMO support keeps the filter pleats at optimum spacing, allowing for maximum loading on the media, and more effective pulse cleaning. RMO support ribs are continuous for the full length of the pleats ensuring no pleat collapse. RMO structures ensure media surface area is maximized, and the entire filter is used to its full potential.


Traditional Filter Design

In traditional filter design, the pleats are often pinched closed.  The clean area seen on the inside of these pleats indicates that the dirty air never reached this media, resulting in less effective loading and ineffective pulse cleaning — and as a result, short filter life.

RoboVent A15 Merv 15 Filter

Discover the Endurex™ A15: The Smarter Choice

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.
