Product overview
What it is and where it fits.
This all-aluminium filter stacks nine layers of expanded aluminium mesh, graded from coarse to finer openings, so dust is captured progressively through the depth of the filter. It is light, washable and reusable.
It shares the standard modules of our stainless steel filter and is used as a prefilter in industrial ventilation where a lighter, lower-cost metal filter is preferred.

Construction & performance
Construction
Nine layers of expanded aluminum mesh progress from coarse to finer openings to collect dust in industrial ventilation systems.
Maintenance & sizing
All-aluminum construction is washable. Standard sizes and custom dimensions are available.
Selection guide
How to choose.
Aluminium or stainless
Choose aluminium for low weight and cost; choose stainless steel for corrosive atmospheres or aggressive cleaning.

Common questions.
Why are the layers graded from coarse to fine?+
Coarse layers catch larger particles first and fine layers catch smaller ones, spreading the dust load through the depth of the filter so it clogs more slowly.
Are aluminium filters reusable?+
Yes. They can be washed with water or a mild detergent and reused once dry.
