Efficient Laser Fume Extraction System : AD 350
The Donaldson BOFA AD 350 is a compact fume extractor for light-duty laser marking, engraving, coding and cutting. It moves 350 m³/h of air at 96 mbar and runs below 62 dB(A). A DeepPleat pre-filter catches larger particles. A combined filter then removes fine particles with a HEPA stage (99.997% at 0.3 microns) and gases with 7.5 kg of activated carbon. It measures 590 × 375 × 465 mm, weighs 35 kg and runs on 115–230 V. It carries UKCA, CE, cUL and UL approval.
United Spectrum Instruments is the official BOFA distributor in India. We supply, install and service the AD 350 across the country.
Understanding AD 350
The AD 350 gives reliable fume control for light-duty laser systems where safety and space matter. A pre-filter and a combined HEPA and carbon filter capture fine dust and harmful gases. Quiet fans keep the workspace comfortable. Carry handles make it easy to place next to a compact laser. Low running costs and a sturdy build make it a cost-effective choice for continuous use.
