Dust Extraction

The EHS Large Diameter Ventilation Sleeve provides localized dust extraction to contain airborne dust and vapor. The full perimeter slot design provides 360 degrees of extraction to ensure that proper air velocity is maintained in the dust zone despite obstructions, such as an operator’s hand or a drum liner.


The Large Diameter Ventilation Sleeve has a removable cover that provides wipe-down access to all surfaces of the sleeve.
