Gel Seal Ducted Terminal HEPA / ULPA Module


The CS (Channel Seal) HEPA Ceiling Module is an ideal terminal HEPA filter module for pharmaceutical and biotechnology facilities, or for any other facility requiring clean-room level air filtration.

The CS HEPA Ceiling Module has been designed so that HEPA filters can be replaced and tested without disturbing the module housing.

Standard Features

  • Galvanised housing powder-coated white on the inside.
  • 304SS Fully welded HEPA filter retaining assembly.
  • Airflow distribution plate located on inlet to disperse air uniformly across HEPA filter.
  • Gel-seal design offers superior protection against bypass leakage.
  • 304SS Perforated screen.
  • 40mm “Turned-up” edge provides superior sealing against varying ceiling types.
  • Includes a static pressure port for evaluating HEPA filter pressure drop, or sampling of the upstream aerosol concentration during filter scan testing.
  • Nominal 50mm Deep AirePanel CS Mini-pleat HEPA filter H14 to EN1822:2009

Optional Features

  • Fully welded construction in either galvanised, 304 or 316 Stainless Steel.
  • Full powder-coated finish.
  • Powder-coated swirl diffuser.
  • Adjustable butterfly damper
  • Roomside aerosol injection port
  • 100mm Deep AirePanel CS Mini-Pleat HEPA filter H14 to EN1822:2009 (lower initial pressure drop)
  • Nominal 50mm & 100mm AirePanel CS Mini-Pleat ULPA filters H14 to EN1822:2009


Airepure® AirePanel CS Mini-Pleat filters used in the CS HEPA modules utilise “gel seal” technology. Instead of a gasket, the filter has a perimeter channel filled with “Gel” seal, a self-adhesive, self-healing silicone compound. When the filter is raised into position, a knife edge flange in the module penetrates into the gel channel, thereby creating a leak-tight interface. Four simple retainers located on the corners of the module are then turned 90° degrees to hold the filter in place, thereby guarantying a uniform and permanent seal between filter and housing. Gel seal technology eliminates the bypass problems usually associated with gasket seal applications. Gel seal filters provide a superior leak free protection critical for cleanroom installations.
