MiniCube™ Series

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.

Portable, Hi-Vac Filtration System

With the MiniCube, you don’t have to sacrifice performance for portability. Our smallest hi-vac dust collector is rated for continuous production, so it can keep working as long as you do. And with the built-in wheels, it can go with you wherever you need it to. The MiniCube provides hi-vac extraction for capture right at the source. It’s the perfect choice for shops where space is at a premium or operators are highly mobile.

  • Powerful: The MiniCube supports one or two RoboVent Extractor fume guns to provide effective, efficient air filtration. It is rated for continuous use, making it appropriate for high-production welding environments.
  • Portable: The MiniCube is small enough to fit almost anywhere and light enough for a single welder to move wherever it is needed. The built-in wheels make it the perfect choice for high-mobility welding applications using fume guns and other hi-vac accessories.
  • Easy: The MiniCube has been designed for ease of use and low maintenance, from automatic start and stop (optional) to the easy dashboard controls—just plug and play!
  • Quiet: The MiniCube generates 68 decibels when in use, making it one of the quietest hi-vac units on the market with additional noise-reducing features to improve operator comfort and acceptance.

The RoboVent Extractor™

MiniCube and Extractor : Another Perfect Pair

The RoboVent MiniCube pairs perfectly with the RoboVent Extractor™ fume gun to collect weld fumes right at the source. Each MiniCube can support one Extractor fume gun. It’s an ideal combination for applications where welders need to stay highly mobile or are working in tight spaces that make other forms of source capture hard to implement.

The Extractor fume gun collects up to 95% of weld fumes as they are generated. An optional Start/Stop can turn the MiniCube on and off automatically with the fume gun for maximum convenience and energy savings. The MiniCube is extremely efficient when working on large weldments because the unit can be moved along with the welder ensuring maximum extraction where needed.

One Gun or Two?

Select the style that best suits your application.


(One Gun)

The MiniCube was designed specifically to pair with one RoboVent Extractor Fume Gun. The combination of the MiniCube and Extractor capture up to 95% of weld fumes with a filter efficiency of more than 99%. This lightweight, compact and portable unit is ideal when the job requires the welder to be mobile.

MiniCube Duo

(Two Guns)

The MiniCube Duo was designed specifically to pair with two RoboVent Extractor Fume Guns. The combination of the MiniCube Duo and Extractors capture up to 95% of weld fumes with a filter efficiency of more than 99%. This lightweight, compact and portable unit is ideal when the job requires the welder to be mobile.

How it Works

AWheels: Large rubber wheels allow the unit to be easily moved throughout the facility.

BFilter Loading Indicator: A yellow light will indicate when the filters are loaded and need to be changed.

CAutoSaver Automatic Start/Stop (optional): The MiniCube turns on and off with the weld torch to save energy.

DAdjustable Airflow: You can easily adjust airflow to the right extraction speed for your application or to compensate for filter loading.

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

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

GCabinet Vent: Keeps interior of unit and respective components cool and functioning properly.

HEasy-Change Dust Tray: The dust tray can be fitted with plastic liners for easy disposal of collected dust.

IHeavy-Duty Construction: The MiniCube is built to last, with 14-gauge steel construction of the cabinet.

Standard Features

24-Hour Support

RoboVent's 24-hour support—at 888.RoboVent—is a promise that a RoboVent expert is available at all times for any need.

eDrive™ Automatic VFD

Constantly monitoring airflow, the eDrive automatically changes motor RPM to adjust for filter loading. This significantly cuts energy use and extends filter life.

Rugged Cabinet Design

RoboVent's dust collectors are housed in a rugged, modular cabinet that is covered—along with structural components—by a 15-year warranty.


RoboVent promises every customer will be satisfied, and that promise is in writing. RoboVent's warranty is the best in the industry.

60 Minute On-Site Assembly

RoboVent collectors come pre-assembled, so on-site assembly takes less than 60 minutes!

Built-in Noise Reduction

Multiple measures contribute to noise reduction in RoboVent dust collectors, improving the work environment and helping to meet noise regulations.
