Duovee (2-pocket) and Triovee (3-pocket) filters are suitable for a wide range of general air conditioning applications in office, shopping centres, hotels, public buildings, hospitals, pharmaceutical factories and other industries requiring clean conditions. The bags are self supporting and particularly suitable for variable air volume systems.
No Pre-Filter
Duovee bags are manufactured from synthetic fibres, specially blended to provide two stages of filtration and maximum dust holding capacity. The combination of ‘first’ and ‘second’ stage filtration eliminates the need for separate pre-filter arrangements, therefore providing very considerable savings in space and capital cost.
Long-Life
The ‘filtration in depth’ properties of the two-stage media provide for very high dust holding capacities and therefore prolonged filter life between bag replacements.
Simple Bag Replacement
Duovee and Triovee bags are attached to a support wire header which in turn is installed within the outer holding frame fixture. Removal and replacement of the bag ‘modules’ is therefore simple and speedy.
Performance Testing
Filters are tested to AS1324.2.4 and 5. Test laboratory is accredited by the National Association of Testing Authorities, Australia. Accreditation number 13213.
Performance tests are conducted at least once every 5 years within a controlled environment in accordance with NATA and Australian Standards requirement

Original Duovee and Triovee pocket bags, designed and manufactured by AES Environmental for over 30 years, contain specific design traits that render them unique within the market. Other products available locally may look similar, however, AES Triovee and Duovee Bag Filters have at least an extra 2mm diameter in the supporting wire and a unique design to instill bag rigidity. This ensures the AES Environmentals’ filter design will have a stronger hold into the frame under all situations, while a weaker bag filter will distort and let air bypass the filter. Likewise the unique rigid pocket design ensures that the bag cannot ‘flap’ with the wind and shed dust particles on the clean air side of the filter.
Feedback should be sought from the AES Environmental sales and service team. Our team is a competent blend of air filtration professionals that specialise in filtration products manufacturing and development, dust collection and fume extraction, laminar flow, HEPA filter and cleanroom applications. During and site visit the technician can either explain the technical advantages of filters with customers and offer solutions that are be of benefit to building and occupant health.
