More safety and better performance in torch extraction

"There is a general trend where there is more attention to the health of workers on the floor. Among other things, we see this reflected in the increasing demand for torch extraction," said Rik Amand, welding specialist at Nederman. The company recently released the Fume Eliminator 860 (FE 860), designed for improved functionality, better performance and more safety in torch extraction.

"The risk of a welder or operator being exposed to hazardous fumes is minimized when the extraction is done at the source," explains Rik Amand. "Torches where the extraction nozzle is integrated into the torch were heavy and bulky in the past, but this is evolving. Today they are much more comfortable to hold, while performance has improved enormously, both in terms of capacity and quality."

25kPA and an airflow of 180m3/h

Amand explains this further using the recently launched mobile FE860, which Nederman designed specifically for torch extraction. "This one uses a very powerful motor. The increased capacity of the motor, combined with the new 50-millimeter hose and improved mechanical design, improves performance (up to 25 kPa and an airflow of 180 m3/h). This makes the system very suitable for demanding torch applications, while the welding fumes do not endanger the welder's health."

Nanofiber filter

The filter has also undergone an evolution. "The F9/MERV 14 nanofiber filter used has been strengthened to handle the higher pressure of the new engines. The filter is still 5.3 m2, but the filter life has been increased compared to the old FE840/841, due to the improved system performance." The filtration rate has also been greatly improved.

Sensor technology ensures reliable flow rates

The flow rate is guaranteed at all times, even at higher saturation levels. Rik Amand: "The filter has a higher lifetime - up to five times higher - and can capture up to thirty percent more dust without impacting the flow rate. Every torch needs an exact flow rate. In combination with a specific torch, the device can be set to a specific flow rate. The mobile torch extractor is equipped with a sensor that then monitors this flow rate. After a certain period of time, the filter will saturate, which makes sense. The sensor makes sure that the motor is adjusted so that you maintain the same vacuum and, therefore, the same flow rate is guaranteed. The welder has a guaranteed flow rate at all times. In addition, the unit gives a warning when the filter has a saturation level of about 85 percent. Thus, the user still has enough time to order a new filter and replace it. This safety margin is built in so that the welder is never faced with a fait accompli that his filter is unexpectedly full. That's a nice touch."

Safe

Rik Amand expects this unit to be in high demand because it provides both increased safety and improved performance. "It is a portable, compact device that the welder can use both on his workbench and on the move, perfect for those who need to perform regular maintenance work and want to remain free of harmful welding fumes."
