Airepure Australia has been the trusted provider of quality HEPA and HEGA containment systems and solutions for military, pharmaceutical, hospital, and biotech lab facilities for over 20 years within the Australian market.
Our locally designed custom engineered solutions and quality containment filtration products have set the standard for the control of nuclear, biological, and chemical airborne hazards.
Airepure have local and experienced technical support personnel available nationally. Our in-house engineering, estimation and technical service departments will support you – from system design to installation, as well as after sales service and ongoing maintenance of your custom engineered containment filtration system.
Our national team of NATA certified on-site technicians can service your existing exhaust filtration containment systems, replacing pre-filters and HEPA filters from our stock, testing and validating HEPA filters to meet Australian Standards.
We can provide the following quality fluid and gasket seal housings:
Many filter systems are associated with critical applications. A critical application is one that uses material that could be harmful to the of health of personnel. Regulatory agencies often mandate inplace testing as a prerequisite before the critical filter system becomes operational. Most installed filter systems are in-place tested per ASME N510, Testing of Nuclear Air Treatment Systems. The ASME N510 test determines the gross test agent bypassing the HEPA filter(s) or carbon adsorber(s). The ASME N510 test procedure requires that the filter system meet a series of pretests to assure testability.
Procedures are as follows:
In-place acceptance or surveillance testing of standard HEPA filters, after the filters have been installed, is a common requirement for users of HEPA filters systems. This in-place testing is necessary to insure that an installed filtration system meets minimum specified filtering efficiencies. Many HEPA filter systems are associated with critical applications. A filter system can have some penetration and still meet the system acceptance criteria. This penetration may be due to a pinhole in the filter media or any number of reasons. If a leak is a large one, the filter will have unacceptable gross penetration. But, if the leak is small enough, any penetration would be diluted by surrounding clean air, the leak will remain undetected. The material used in some laboratories is so dangerous that the ASME N510 overall in-place leak test method alone may not be adequate. That is, any leaks no matter how small∫are unacceptable. The capability to detect and accurately locate pinhole leaks becomes imperative. Scan testing provides this capability. Some types of HEPA filters are routinely scan tested during factory production test to locate pinhole leaks. Installations such as cleanrooms customarily use the scan test as an acceptance test. Scan testing, will also locate pinhole leaks in filters installed in side access filter housings.
Our bubble-tight isolation dampers are specifically designed to provide cost effective isolation of filter banks with high volumes of air. Each bubble-tight damper is leak tested at the factory to insure a bubble-tight seal at a differential pressure of 10 inches water gauge. Isolation dampers are available with the standard manual actuator or optional electric or pneumatic actuators.
Airepure can design, build, and test custom air filtration systems for specific applications, manufactured to meet the requirements of customer specification including: blowers, outlet stacks, skids, seismic qualification, upflow and downflow arrangements, heaters, chillers, and insulation. Complete control and instrumentation packages can be engineered and factory assembled to provide you with a turn-key system. All system connections are manufactured to facilitate installation into the customers process. Customized manufacturing of total filtration systems enhances the integrity of the systems and simplifies installation and in-place testing.
Custom engineered filtration system can be designed to provide protection against chemical, biological, and radioactive warfare agents. High quality bag-in/bag-out filter housings typically contain prefilters and High Efficiency Particulate Air (HEPA) filters to control contaminants such as micro-organisms, viruses, and radioactive particles. The system also houses a High Efficiency Gas Adsorber (HEGA) with a special carbon to control the gas and vapor phase contaminants.
High Efficiency Gas Adsorbers (HEGA)
HEGAs are most often used for containment of toxic gases in air filtration systems. A HEGA collects gaseous contaminants from an airstream through adsorption. With a properly designed system, any adsorbable contaminant can be filtered and contained. All HEGAs are factory tested to a minimum mechanical efficiency of 99.9 percent.
High Efficiency Particulate Air (HEPA) Filters
Flanders/CSC has the most complete line of HEPA filters available. We offer many choices in frame materials, size, efficiency, testing criteria, temperature rating, and airflow capacity. We supply the highest quality HEPA filters to the most demanding customers throughout the world. HEPA filters are tested in accordance with IES-RP-CC001.3, “HEPA and ULPA filters”.
