Extractor250 Consumables

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.

Ambient_Filtration

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.

SourceCapture_Filtration

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.

Ambient_Exhaust

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.

SourceCapture_Exhaust
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.

Consumables for every application.

We have a full range of fume gun consumables for every welding application, from stainless steel to aluminum. Use genuine RoboVent replacement parts to ensure the best performance from your fume gun.

Nozzles

The Extractor250 is available with four nozzle options – 12mm Standard, 14mm Special and 14mm. You can switch the nozzles in seconds. Thus,  the range of application is broadened to almost any single need you might have as a welder.

A) 12mm  – The standard nozzle for the Extractor250. The nozzles offers slightly wider shielding gas coverage on medium-thickness materials in butt and fillet applications, and outside-corner joints.

B) 14mm Special – For heavier-thickness, high-current and high-deposition butt- and lap-joint applications, this nozzle offers greater shielding gas coverage to help prevent porosity.

C) 14mm – Where space is limited and fit is tight on acute-angled fillet joints, or into steep prepped roots on heavy-thickness butt-joints, this nozzle offers better access and greater shielding gas coverage to reduce porosity.

D) 14mm Extended – The Extended nozzle is perfect for hard-to-reach spots where the fume gun may be too big to fit.
