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.

RoboVent ProCube™ Hi-Vac Filtration System

When you need power, flexibility and mobility, look to the RoboVent ProCube™. The ProCube puts high-vacuum filtration power into a small, portable package that goes wherever you need it. Designed especially for the RoboVent Extractor™ Fume Gun, ProCube is the only portable filtration unit of its size that is rated for high-production welding environments. ProCube is:

  • Powerful: The ProCube can be hooked up to a single robotic cell or any MIG welding application to provide effective, efficient air filtration. It is rated for continuous use, making it appropriate for high-production welding environments.
  • Portable: At just 210lbs(95kg), 42”(106cm) high and with a 24”(70cm) x 16.5”(42cm) footprint, the ProCube is small enough to fit almost anywhere and light enough to move wherever it is needed. The optional wheels and handle make it easy for a single welder to move, making it the perfect choice for high-mobility welding applications using fume guns.
  • Easy: The ProCube has been designed for ease of use, from automatic start and stop to the easy dashboard controls—just plug and play! Maintenance is minimal with the automatic filter cleaning system and disposable dust collection tubes.
  • Quiet: The ProCube generates 68 decibels when in use, making it one of the quietest hi-vacuum units on the market with additional noise-reducing features to improve operator comfort and acceptance.

ProCube and Extractor : The Perfect Pair

RoboVent ProCube is the perfect companion for the RoboVent Extractor Fume Gun. In fact, the two were designed to go together.

The unit will automatically start when the torch is on, and stop when it is off, for easy operation and energy savings.

The ProCube’s size and portability make it an excellent choice for high-mobility applications such as shipbuilding or large fabricated components. The long reach of the Extractor hose gives welders exceptional mobility, and the ProCube can be easily moved along with the welder.

How it Works

ADashboard: An easy-to-use, user-friendly dashboard lets you see performance and filter loading at a glance with all controls on the top of the unit.

BeDrive: The eDrive system constantly monitors airflow and automatically adjusts the motor RPM to compensate for filter loading, cutting energy use by 20% to 30% while extending filter life by as much as 30%.

CAutomatic Filter Cleaning System: Filters are automatically cleaned using compressed air to minimize maintenance and extend filter life.

DDelta3 Spark Arrestor: Our proprietary built-in Delta3 spark arrestance system comes standard with every ProCube air filtration unit for superior fire safety. Delta3 uses centrifugal force to eliminate sparks at the source.

EBlower Inlet Relief Valve: The relief valve protects the ProCube from harmful overpressure if airflow becomes obstructed.

FExhaust Silencer: The exhaust silencer reduces generated noise from our already quiet system by a further 10-15 decibels to improve operator comfort.

GDust Tube: Replaceable dust tubes with caps allow for clean, fast and hassle-free disposal of collected dust.

HHours Run Meter (Option): A simple and effective way to monitor equipment usage and filter life .

IWheel and Handle (Option): Large rubber wheels and a sturdy handle allow the unit to be easily moved throughout the facility.
