Recirculating UCV systems require high efficiency terminal filters to prevent recirculation of bacteria. AES Environmental UCV HEPA filters are tested to 99.99% by Hot DOP to AS4260 to ensure full protection. For even higher protection, STATE-OF-THE-ART FILTRATION
ULPA filters, tested to 99.999% efficiency can be supplied. Whilst filters tested to 95% by the sodium flame test may suffice where a system employs 100% fresh air supply, consideration should be given to any risk posed by their lower efficiency.
CONSTRUCTION
Plenum zinc seal (zincanneal) steel, finished with a laboratory grade coating that is solvent, alkali and acid resistant to provide a durable and easily cleaned surface finish. The diffuser is constructed from perforated stainless steel which assists with the distribution of airflow. Variable speed direct drive centrifugal fan/blowers enable airflow adjustment throughout the filter life and allow adjustment of the supply air velocity. The filters are sealed in place by a unique two-part silicone gel designed to create and preserve an airtight seal between the filter and the filter housing. The gel is factory installed and factory cured in the filter frame. Once cured, it has the self-healing qualities of a liquid while retaining the stability and non-flow characteristics of a solid. The risk of air bypass from conventional gaskets and seals is effectively eliminated. HEPA or high performance ULPA filters with unique fluid seals. Medium-efficiency disposable pre-filters are fitted behind the hinged return air grilles to extend the life of the main filter. All filters are individually tested in strict accordance with the requirements of Standards Australia and the performance of the pre-filters and final filters is continuously monitored by Magnahelic differential pressure gauges.
