Replacement G4 Coarse Dust Filter for WDH-AF500B

The G4 replacement coarse dust filter for the WDH-AF500B industrial air purifier serves as an effective pre-filter for capturing coarse dust particles. It protects the downstream main filter and is particularly suitable for use in industry, trade, construction, and renovation.

Effective pre-filter for protecting the main filter: The G4 filter captures coarse particles from a size of 10 µm with a filter efficiency of over 90%. This reduces the load on the downstream filter of the WDH-AF500B and protects it from rapid contamination.

Advantages of the G4 coarse dust filter

  • Efficient pre-filtration: Removes over 90% of coarse suspended particles and dust particles from 10 µm from the intake air.
  • Protection of the main filter: Reduces the dust load on the downstream filter, which can extend its service life.
  • Suitable for high dust loads: Particularly practical for use in industrial, construction, renovation, and trade settings.
  • Easy filter replacement: The custom-fit replacement filter can be easily swapped out on the WDH-AF500B.

For industry, construction, and renovation

The G4 coarse dust filter is suitable for environments where large amounts of dust and dirt particles are generated. These include, for example, production halls, workshops, construction sites, and renovation areas.

  • Industry & Trade: For pre-filtration during dust-intensive work in workshops and production areas.
  • Construction industry: Suitable for separating coarse construction and work dust.
  • Renovation: Supports air purification during grinding, sawing, drilling, and chiseling work.
  • Protection of the air purifier: Relieves the downstream filter stage and contributes to reliable operation.

G4 pre-filter for the WDH-AF500B
