The individual extraction devices mounted on the columns in the hall were not adequately tackling the air pollution arising due to aerosols (welding fumes and dry dust) in the metalworking department.
Mobile extraction units and fixed vents could not be used due to lack of space and the numerous cranes. A range of concepts were drawn up with the customer to best meet the individual requirements for a exhaust system that was up to the task. The result is a decentralized filtration solution with permanent extraction, which catches and cleans rising smoke and dust, with the aid of four manifolds above the crane runway and adjustable air inlets, and returns the purified air via ground-level inlet openings. Continuous changeover between exhaust air duct and the recirculation system is also possible.
A powerful filtration system for unique challenges
To meet the high requirements, such as an effective extraction volume of 20,000 m3/h, LTA Lufttechnik GmbH selected a DF24000-JET cartridge filtration system, which collects the rising smoke and dust using four manifolds above the crane runway with adjustable air inlets and returns the purified air via ground-level inlet openings.
"The extraction system for the metalworking department proves once again that LTA keeps on raising the bar in the field ofdecentralized filtration solutions. They have the ingenuity to solve even the most difficult of tasks to the customer’s complete satisfaction, to raise both cleanliness, occupational safety and employee satisfaction. Not only is the new filter system from LTA considerably more efficient than its predecessor, it also plays a key role in reducing general risk to health."
