Product Description
The Castle HEPA Filter Box is a sealed terminal enclosure that houses a high-efficiency particulate air filter and delivers highly purified air where air quality is critical. Combining a leak-tight housing with an EN 1822-certified filter element, it removes airborne particles — dust, pollen, bacteria, mold spores — before the air enters the space. Available with Top, Side or Zed inlet configurations and a choice of perforated or swirl diffuser face, mounted in ceilings, walls or ductwork as a terminal unit in cleanrooms, healthcare and pharmaceutical facilities.
