LOEBAU, Austria, April 11, 2016 — ULT AG has announced the LAS 300.81-HFM054, an explosive-atmosphere-certified extraction and filtration unit with H class filtration, suited for the removal of combustible dusts. The unit is suited for the extraction and filtration of dry dust particles with a threshold limit value of <0.1 mg/m3, as well as carcinogenic emissions. It is also is an extraction and filtration system for combustible dusts according to dust explosion category 1 and explosive dust-air mixtures that are neither self-ignitable nor pyrophoric. The unit has been developed for extraction and filtration of dry dusts that occur during laser processing such as cutting, engraving or structuring. It features a combination of cartridge and storage filters. The filter’s materials ensure an efficient separation of various particulate matters. The main filtration module consists of two class-M cartridge filters with optional Teflon coating, which are jet stream cleaned at regular intervals. The stationary extraction and filtration unit is equipped with stepless volume flow control, filter condition indicator and interface for control by means of external systems. It complies with statutory dust limits, efficiently protecting employees, systems and products from airborne pollutants that occur in material processing through laser technology.
