Plaser® 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.

Air Filtration for Today's Most Advanced Plasma and Laser Cutting Processes

At RoboVent we utilize plasma cutting for our own manufacturing, so we understand advanced-cutting processes and laser welding. Because of this experience, we have developed advanced collectors to remedy the serious dust and fumes produced by these processes. The advantages for these processes are well known: increased production efficiency, lower consumable costs, lower direct labor costs through automation and so on. These advantages apply to plasma cutting operations, as well. However, as any operator of these processes knows, there are also challenges involved. Smoke from laser welding can be so thick that it can diffuse the beam. This reduces the intensity of the beam and can interfere with the process. Also, maintenance costs for these processes can rise if smoke is not extracted properly. Dust and fumes from these processes often contain toxic substances, so protection for workers is a must. Despite these challenges, these new laser and plasma-powered processes carry many benefits and are growing in popularity.

RoboVent's Plaser Series of collectors is designed specifically for these processes. These collectors are based on our decades of experience in the industry. Over 1,000 Plaser units deployed in manufacturing operations have demonstrated the many benefits of our filtration technology. In fact, RoboVent has partnered with several major manufacturers of thermal cutting systems, including the Mazak Optonics, ALLtra Corp. and Hornet Cutting Systems. RoboVent's Plaser Series is the perfect air quality solution for these cutting-edge processes.

Benefits of the Plaser Series include:

  • Lower operating costs: We're always looking for ways to reduce energy use, such as automated systems to ensure collectors run only when they need to. Additionally, our filters and equipment have been engineered to maximize filter life and reduce operating costs.
  • Superior safety and risk reduction: We have deep experience in controlling combustible dusts. Every piece of equipment we make is engineered to reduce the danger of fires or other problems that could put your workers and assets at risk. The Delta3 Spark Arrestor (optional) is our cutting-edge technology to kill sparks before they cause problems.
  • Easy maintenance: The Plaser Series is designed to work with the best filters in the industry. For example, the Endurex B16 PTFE filter (optional) is not only superior-performing but is one of the longest-lasting filters available. Our filters and equipment are built with the goal of reducing the maintenance burden on your staff. Our software platform achieves the same goal—with eTell intelligent controls, you can move beyond preventative maintenance to truly predictive maintenance.

The Plaser Series is designed to minimize operational and maintenance costs. The standard features and options available—such as rugged construction, vertical filters, filter pulsing, ePad Control Panels, eDrive and RMO Technology—not only ensure the longevity of the collector itself, but provide energy savings and longer filter life!


How The Plaser Series Works

ePad Control Panel Each Plaser unit comes standard with ePad, an easy-to-use touch-screen panel putting system controls right at your fingertips.

ASafeSensor™ Particulate Monitoring SafeSensor is the Plaser’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.

BFilter Pulsing System This system takes filter cleaning to an entirely new level. Far more than just a simple blast of compressed air, it has multiple valves working together in a sequence to virtually eliminate re-entrainment while propelling the dust down into the collection area.

CEndurex™ RMO Filters RoboVent’s Endurex RMO filters use Reinforced Media Optimization and a rigorous quality control system to guarantee performance. In addition to RMO Technology™ a wide selection of media is available including high performance cellulose, NanoFiber, and PTFE, so that the filters can be tailored specifically to the application.

DSupprex-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.

EeDrive™ Automatic VFD – Option 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%.
