H Class Dust Extractors
Dust extractors are tested internationally according to three standards: Low, Medium and High. Husqvarna dust extractors meet the High-Classification standard (EN-60335-2-69), so their S11, S26, S36 and T7500 models are all H classified.
H-Classification complies with the most stringent quality levels, requiring a filtration efficiency of 99.9% distributing particle sizes of less than 1mm. Husqvarna machines have been demonstrated to achieve more than 99.95% efficiency with particle sizes of 0.3mm
The Highest international standard also requires dust-free handling.
Husqvarna’s trademarked Longopac dust collection bag system ensures that the dust does not become airborne, either during operation or when changing the bag.
