Replacement Coarse Dust Filter G4

Effective Pre-filter for Industrial Applications | Suitable for WDH-AF500B

The high-quality replacement coarse dust filter of filter class G4 has been specially developed for the WDH-AF500B industrial air purifier. It serves as the first barrier against coarse particles in heavily contaminated environments and ensures reliable air purification directly at the source.

HEPA Filter Protection & Value Retention: By filtering out particles larger than 10 µm with an efficiency of over 90%, the G4 filter mat protects the sensitive, downstream HEPA main filter from premature clogging and significantly extends its service life.

Features & Benefits

  • Efficient Pre-filtration: Reliably filters out over 90% of coarse suspended particles and particles larger than 10 µm from the room air.
  • Operational Cost Optimization: Protects more expensive main filter media from rapid wear and tear, thereby reducing ongoing maintenance costs.
  • Easy Handling: Precisely manufactured for quick, straightforward, and tool-free filter replacement on the industrial air purifier.

Application Examples

  • Industry & Crafts: Ideal for effective air purification and permanent dust extraction directly in production halls, workshops, or on construction sites.
  • Construction & Renovation: Reliably captures stubborn coarse dusts such as sawdust, grinding and chiselling dust, as well as residues from tile adhesive and fastening materials.
