Mobile extraction & filtration
Filtration system vendor ULT AG has extended its model series LAS 260 by developing a new extraction system for laser and welding fumes, the LAS 260.HD 19 W3.
The portable device meets the certification requirements according to DIN EN ISO15012-1 welding fume separation class W3.
The LAS 260.HD19 W3 is qualified for extraction and filtration of fumes that occur in cutting and joining alloyed as well as unalloyed steels by welding and related processes. This includes high-alloyed chrome and nickel steels. In accordance with the German air purification regulations TRGS 560 and TRGS 528, cleaned air can be returned to the working environment.
The system extension provides a volume flow rate of up to 340 m³/h at a vacuum max of 8,300 Pa. Long filter lives are said to be guaranteed by the utilisation of an F9 filter cassette and F14 particle filter cassette. Consequently, users obtain an economic solution to significantly reduce costs in terms of filter exchange and energy management.
An integral part of the system is a minimum volume flow control. In the case of blocked extraction, optical and acoustic warning signals are emitted.
