HEPA Filters

    Lower Resistance to Airflow
    Low-cost option for applications that have a higher tolerance to variable air volume
    Each filter has guaranteed efficiencies and resistance to airflow

AES Environmental manufactures a range of a Vokes HEPA filters. HEPA Filters are designed for use in such critical applications as: 

  • Hospital operating theatres- Sterile goods processing- Biological safety cabinets 
  • Radioactive particle containment- Miniature electronic component manufacture 
  • Precision instrument assembly 
  • Cleanrooms and Pharmaceutical Production  
  • Biological Safety Cabinets and Research Applications  

Vokes Deep Bed HEPA filters consist of a glass-paper filtering medium pleated into a narrow vee formation and held in place by corrugated aluminium separators. The filter assembly is enclosed in a metal frame that can also be supplied with extended flanges for downflow applications. The HEPA filters are available in a variety of frame and separator materials and sealant types for specialised applications. Vokes Fluid seal is recommended to overcome the need for gaskets and mounting clamps in downflow installations. 

In addition to the deep bed production line, AES operates a minipleat production line. The minipleat HEPA filter is designed to be a low-cost option for applications that have a higher tolerance to variable air volume (non-laminar flow). The Vokes minipleat HEPA Filters are made from the same filtering media as conventional HEPAs, however the media is in narrow pleat formation separated by beads of a special hot-melt compound. The resulting light weight and compact dimensions of a minipleat filter make them the ideal choice for low-profile ceiling modules where they can be utilised in cleanroom applications. 

Lower Resistance to Airflow: Vokes’ high-performance design provides a higher air flow capacity and in turn aids in energy savings and a reduction over life-cycle costs. 

Individually Tested: Every filter is tested on a special rig to ensure that it complies with the rigorous performance requirements of the required testing certification. Each filter has guaranteed efficiencies and resistance to airflow. The results of this testing, together with the filter code and the test airflow, are given on serialised certification labels attached to the filter and its carton, providing easy and rapid identification.
