Spire™ 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.

Powerful filtration with the smallest footprint in the industry.

If you’re using robotic welding cells, Spire may be the right system for you. We designed Spire especially for the most common types of welding applications. Spire is a flexible, cost-effective alternative to centralized ducted systems.

Each Spire unit provides filtration for up to two robotic weld cells. It’s a powerful system that can keep up with the heavy demands of robotic welding in a high-production factory.

Spire features:

  • Small footprint: Our floor-saving design takes up about the same amount of space as a wire barrel.
  • Very low maintenance: Everything is easily accessible for fast filter changes and maintenance—no special tools required.
  • Flexible: Since the Spire units have a very small footprint, it’s easy to find space for them. And whenever you need to change your floor configuration, Spire is easy to move right along with your welding cell.

Spire Configuration

Flexible, movable single collectors.

Our spire configuration uses smaller collectors, one for each welding cell, ducted to the hood over the cell. This system is very flexible, simple to install and maintain, and easy to move with the welding cell. The single filter design makes filter change out fast and easy. Includes built-in spark arrestance.

ePro Controls

This extra-large 7” full-color Human Machine Interface (HMI) is easy to see, easy to understand and gives you access to everything you need to keep your system running smoothly. You can control the pulse timing and trigger points, set filter service alarms, setup automatic run schedules, operate and control the blower speed, monitor filter pressure and see operation events all with the simple push of a couple of buttons.

How it Works

ADeflector Plates Deflector Plates within the top of the dust cabinet which protect filters from particulate abrasion, creates a high-velocity airstream around the filters to bring more dust into the containment chamber.

BPulsing System Pulse nozzles are engineered to create high level shock wave through the entire filter dislodging dust from the filter pleats sending the captured dust to the dust holding bin.

CPleatLock Filters RoboVent’s new PleatLock technology has been engineered to outlast even the toughest competitor filter. With added dimples within the pleats, there is up to 35% more media space to capture more particulate, allowing for longer time between filter changes. This saves time and money!

DePro Controls The new 7” full-color, HMI Control Panel is easy to see, easy to use and easy to understand while helping to keep the system running smoothly and operators informed. The Control Panel is mounted in the electrical control box which can be installed on the side of the unit or tethered to where it is more convenient.

EeDrive™ Automatic VFD The eDrive constantly monitors airflow and automatically adjusts the motor RPM to compensate for filter loading. Energy peaks and valleys are evened out and energy usage is cut by 20% to 30%, while filter life is extended by as much as 30%.

FSafeSensor Particulate Monitoring SafeSensor is the Spire’s advanced particulate-monitoring device that can detect leaks past the filters. If one should occur, SafeSensor will shut the equipment down and trigger an alarm.

GSupprex-200™ Fire Suppression System – Option This is a dual-stage system activated by smoke or heat. If smoke is detected, a fire damper closes, stopping all airflow and oxygen supply. If heat is detected, FM-200 gas is instantly deployed.

HDust Containment More dust containment (15 gallons) – which means less servicing and better performance of the unit with more consistent CFM & Static pressure. Simply pull out the drawer and dispose of the dust.
