Black mesh cover for small axial fans: keeps dust and insects out of the opening while leaving the impeller serviceable.
Share to:

Overview

A simple mesh cover for small fans and ventilation openings. The black finish suits dark equipment housings, and the open weave keeps the airflow loss low compared with a filter.

It is not a filter. It stops insects, coarse dust and fingers, but fine dust passes through — so it is used where the environment is relatively clean or where a separate filter sits behind it.

Where it fits

  • Small equipment housings
  • Ventilation openings on enclosures
  • Consumer and office equipment
  • Protection against insects and coarse debris

Selection and installation notes

Check the mesh against the fan opening. A cover that overlaps the blades will rub and make noise.

For dusty plants, use a filter guard instead. A mesh that passes fine dust still lets the impeller load up.

FAQ

Is it a filter?

No. It stops insects and coarse debris, not fine dust. Use a filter guard where dust control matters.

Will it fit my fan?

Match the cover to the frame and fixing points. Send the fan model or the hole spacing.

Does it reduce airflow?

Slightly, depending on the weave. It is much less restrictive than filter media.

Can it be cleaned?

Yes, by brushing or washing. Let it dry before refitting.
