SKU CH-BYBB-H3X9F

Black plastic dust filter guards protect 50mm case fans with 55x55x7mm frames and 40mm hole spacing

  • Protects components from dust with fine-mesh filter
  • Easy cleaning via removable front plate and filter
  • Durable black plastic construction resists wear
  • Fits 50 mm fans with 40 mm hole centres
  • Two guards included for dual-fan setups

50 mm Fan Dust Filter Guard

Two black plastic guards measuring 55 x 55 x 7 mm protect 50 mm case fans from dust and debris. The removable front plate, back plate and middle filter make cleaning straightforward. Mounting holes are spaced 40 mm centre-to-centre with a 5 mm diameter. The mesh design maintains airflow while keeping components clean.

Mounting hole centre distance 40 mm

The single specification that decides fit is the 40 mm hole-centre spacing, which matches standard 50 mm fan frames. If your fan uses a different screw pattern the guard will not align. No other dimension overrides this requirement.

Tool-free clip installation

The guard snaps onto the fan frame without screws, though the pack includes them for optional secure mounting. The three-piece construction separates for washing but can be fiddly to reassemble if the clips are forced. Ensure the mesh sits flat before clipping to avoid rattling.

Questions about this item

How well does the 50 mm filter guard keep dust out once it is fitted to a case fan?

The plastic mesh blocks dust and debris while the hole pattern still lets air pass through, so internal components stay cleaner and the fan keeps moving air.

What mounting pattern does the 40 mm hole centre distance match?

The 40 mm centre-to-centre spacing with 5 mm diameter holes lines up with standard 50 mm fan frames, so the guard bolts straight onto the fan.

Will the 55 mm square by 7 mm deep guard fit inside my case without fouling cables or panels?

At 55 mm wide and only 7 mm thick the guard adds minimal depth, and the removable front plate makes it easy to clean without removing the whole assembly.
