- 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
- Biological Safety Cabinets and Research Applications
- Sterile goods processing
- Radioactive particle containment
- Miniature electronic component manufacture
- Precision instrument assembly
- Cleanrooms and Pharmaceutical Production
Construction
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. We recommend Vokes Fluid Seal to overcome the need for gaskets and mounting clamps in downflow installations.
Minipleat HEPA Filter
In addition to the deep bed production line, AES operates a minipleat production line. Minipleat HEPA Filters are designed to be a low-cost option for applications that have a higher tolerance to variable air volume (non-laminar flow). Vokes Minipleat HEPA Filters are made from the same filtering media as conventional HEPAs, but feature a 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.
HEPA filters are available in a variety of frame and separator materials and sealant types for specialist applications. Also available are special containment housings, HEPA fan filter modules and portable negative air units. Holding frames that provide effective clamping and sealing of filters are available for ducted applications.
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. Testing results, together with the filter code and the test airflow, are given on serialised certification labels attached to the filter and its carton. Therefore, identification is simple and efficient.
All filters are factory tested by our NATA accredited laboratory.
HEPA Filters are manufactured by AES Environmental on a controlled product line using H&V HEPA media. H14 efficiency of 99.995% is guaranteed by way of Sodium Flame test rig in accordance with AS4260. AES Environmental manufacturers HEPA filters to the stringent construction standards in AS4260 and each HEPA filter is also leak-tested in accordance with AS1807.6 prior to boxing to ensure that each HEPA filter is ready for the most critical applications.
