About PRE FILTER
Industrial air pre-filters serve as the primary stage of defense in HVAC and air handling units (AHUs). They capture larger airborne particles to extend the operating life of high-efficiency secondary or HEPA filters.
- Common Configurations: Available in standard dimensions like 500x500 mm, 610x610 mm, and customized panel cuts.
- Filter Materials: Primarily made with washable synthetic non-woven media or robust metallic wire meshes.
- Frame Styles: Standardized with Aluminium, Galvanized Iron (GI), or Stainless Steel (SS) casings.
- Filtration Rating: Operates within coarse efficiency standards (G2, G3, or G4 ratings) to isolate particles down to 10 microns.
Domestic RO Water Pre-Filters
In domestic and commercial water purifiers, a pre-filter system serves as the external sediment layer that extracts solid impurities from inlet water before it passes to sensitive internal membranes.
- Assembly Parts: Composed of a heavy-duty, food-grade outer plastic housing bowl and internal cartridges.
- Filter Elements: Utilizes Polypropylene (PP) Spun or wound thread candles with 5-micron ratings.
- Core Functions: Removes heavy debris like silt, clay, sand, and visible rust particles from drinking water.
- Maintenance: Cartridges turn yellow or brown as they trap impurities, requiring replacement every 3 to 6 months.
If you are looking for a specific project solution, let me know:
- Is your application for Air Filtration (HVAC/AHU) or Liquid/Water Filtration?
- Do you need a particular micron rating or housing material (e.g., SS, PP, GI)?
