Inlet filter for Milwaukee M18 BLHSB cordless blower, 4933502382

Inlet Filter for the Milwaukee M18 BLHSB Cordless Blower, 4933502382

Article 4933502382 is the inlet (intake) filter of the Milwaukee M18 BLHSB cordless high speed blower. It is a spare part and a consumable - the article is the filter, not the machine. The M18 BLHSB designation says which blower the part belongs to, not what the article is.

Which machine it fits

The filter is for the Milwaukee M18 BLHSB blower. The bare tool version is article 4933500533 (M18 BLHSB-0), sold here as a separate product. Check the designation on your machine's rating plate before ordering - Milwaukee's numbering is long and neighbouring models differ by a single letter.

What the filter does

The filter covers the opening through which the blower draws air. It holds back the dust and the small particles that would otherwise reach the fan and the motor. The pleated element - folded like a concertina - packs a large filtering area into a small circle, while the black ribbed frame protects the folds during work and during a change.

When to replace it

Replace it when the air stream weakens for no other visible reason, when the pleats have darkened and tapping the dust out no longer brings them back, and always when the element is torn, deformed or soaked. Working in plaster dust, cement dust and sawdust clogs it many times faster than sweeping leaves outdoors. A machine running with a blocked intake works its motor at a higher load and temperature.

What to check when fitting

Take the battery out before you open the intake. The new filter seats fully and locks by turning the ring to the closed padlock symbol. The sealing rim must sit all the way round with no gap at the side: air that bypasses the filter carries dust straight to the fan. Never run the machine without a filter, not even briefly. For the dismantling sequence the blower's own manual is the authority.
