Air Filter LAF1755
Technical Features
The Air Filter LAF1755 is built around a high-capacity cellulose media core tested under ISO 5011 standards to achieve a 99.9% filtration efficiency rating. Protected by heavy-duty steel inner and outer mesh cages, the Air Filter LAF1755 maintains structural integrity under high vacuum suction. Its heavy-duty top radial seal gasket forms a tight, leak-proof barrier inside the filter housing to prevent unfiltered dust bypass during severe equipment vibration.
