Their size / performance ratio is particularly convenient. They feature a metal prefilter for the outside discharge of fumes. Their cube shape and resistant structure allow easy installation in various configurations. The terminal box allows to automatically start the extraction based on the arc ignition with a time delay. (Energy saving).

The ENGMAR BBM high-vacuum extraction units allow the connection of 1 to 2 extraction welding guns or slit nozzles CHD depending on the model. They feature a metal prefilter and are designed for external discharge of fumes. The extraction units are mounted on a trolley for an easy workplace adaptation and reduction of required floor space. The terminal box allows to automatically start the extraction based on the arc ignition with a time delay. (Energy saving).

The ENGMAR BBTD high-vacuum extraction units allow the connection of 1 to 2 extraction welding guns or 1 to 2 slit nozzles CHD depending on the model.
