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.


High-Powered Fume Extraction for Your Toughest Welding Jobs

High-amperage welding produces heavy-duty weld fumes. The water-cooled RoboVent Extractor500 gives you the amperage and extraction power you need. It puts high-powered fume extraction into a lightweight, ergonomic fume gun that provides excellent control and maneuverability. The Extractor500 is the best choice for high-amperage, continuous-use applications. The water-cooled head reduces the size and weight necessary to handle high amperages. At just 3.25 lbs. (at 3 feet off the ground), the Extractor500 is as comfortable and easy to handle as your favorite standard weld torch.

  • Gas flow and extraction flow are well balanced to give a perfect weld in any position.
  • Collects up to 95% of weld fumes at the source, before they enter the welder’s breathing zone.
  • Rated at 500 amps with a 100% duty cycle.
  • Ergonomic grip design to reduce hand fatigue and a ball-and-socket joint for greater maneuverability.
  • Perfect for large weldments, tight spaces and other environments where welders are highly mobile and source capture of weld fumes is challenging.
  • Available with a 3-meter, 4-meter, 5-meter or 6-meter tapered hose.
  • Choose from 45° or 60 metal necks or a 45° plastic neck.

Customize your fume gun for the perfect weld.

The perfect fume gun is the one that fits your unique needs. Choose from the following options to customize your Extractor500 fume gun for your application and welding style.

  • Plastic or metal neck
