Airepure Australia is the exclusive distributor of Flanders CSC containment products for Australia, New Zealand & Pacific Islands.
For over 35 years, Flanders/CSC has been the prime manufacturer of HEPA and HEGA containment systems for the most advanced military, pharmaceutical, hospital, and biotech lab facilities. Flanders/CSC sets the standard for the control of nuclear, biological, and chemical airborne hazards. Company developments have led to dramatic improvements in bag-in/bag-out housings, remote in-place filter testing capabilities, remotely operated hot cell housings, low leak and bubble tight isolation damper systems, seismic qualification, and the use of fluid seal and gasket seal techniques. Flanders/CSC products have established the benchmark for conscientious design in quality containment filtration.
The BF-Series bag-in/bag-out fluid seal housing is a side servicing filter housing that has been designed to meet the air filtration needs of industries and research facilities that handle dangerous or toxic biological, radiological, or carcinogenic materials.
The BG-Series bag-in/bag-out gasket seal housing is like the BF-series housing, except that it uses the gasket seal design.
The KF-Series non-bag-in/bag-out fluid seal housings are used at industries and research facilities concerned with filtration of potentially hazardous airborne particulates or gases and have the need for a high quality, high efficiency filtration system, but do not need a system which includes the bag-in/bag-out feature.
The KG-Series non-bag-in/bag-out gasket seal housing is like the KF series housing, except that it uses the gasket seal design.
The G-Series round bag-in/bag-out fluid seal housing is designed for the installation of a single HEPA filter or carbon adsorber, in low CFM ventilation systems.
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: 1 After the pretests are completed, a challenge agent is injected upstream of the HEPA filter(s) or carbon adsorber(s). 2 Upstream and downstream concentrations are determined and a system penetration is calculated. 3 The penetration is compared to the acceptance criteria.The system either passes and is operational, or it fails and requires corrective action. Flanders/CSC manufactures in-place test sections that allow testing to ASME N510 standards when there are space restrictions or when isolation of a leaking filter is required.
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, with the use of Flanders/CSC PrecisionScan Test Sections, will also locate pinhole leaks in filters installed in side access filter housings.
The bubble-tight isolation dampers are Flanders/CSCs top-of-the-line dampers. These dampers were specifically designed to provide costeffective 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 gage. Isolation dampers are available with the standard manual actuator or optional electric or pneumatic actuators.
Flanders/CSC can design, build, and test custom air filtration systems for specific applications, using one or more of Flanders/CSCs standard products. We have built these systems from a low of 10 CFM to a high of 36,000 CFM with design pressures from our standard 10 inches water gage up to 15 PSI (415 inches of water gage). Flanders/CSC air filtration systems are manufactured to meet the requirements of the customers 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 the customer 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.
A CBR filtration system is 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”.
