HEPA Filtration Systems

Fan Filter System

Aseptic Enclosures’ HEPAcirc™  Fan Filter System is designed for  simple, “Plug-and-Play” “clean-build” facility implementation.

The HEPAcirc™ is a Hospital/Pharmaceutical CleanRoom Grade, air purification upgrade system. It is ideally suited for simple implementation into existing areas.  It can get the job done without  the need for major,  sometimes impossible, construction.

Design Build Hepa Filtration Systems

Our HEPAcirc™ system features a built-in low-wall return for superior airflow and patient  isolation applications.  It can facilitate safety and cleanroom compliance that could otherwise be impossible. Design/Build customization options are available for specialized applications. It is an important part of our broad air purification systems product line.

UV decontamination can safely be incorporated into the duct work.  It is designed to provide an ISO Class 5 (Class 100) or ISO Class 4 (Class 10) clean air environment suitable for hospital infection control, pharmacy, laboratory, testing, manufacturing, inspection and/or pharmaceutical operations.

Many modules and custom designs available

    Frequently Asked Questions

    What are the different classes of HEPA filters?
    HEPA filters are classified based on their efficiency at capturing particles of 0.3 microns in diameter. Common classifications include E10 to E12, H13 to H14, and U15 to U17, with higher numbers indicating greater efficiency.
    How is HEPA filter efficiency measured?
    HEPA filter efficiency is measured using the Most Penetrating Particle Size (MPPS), typically around 0.3 microns. The efficiency is determined by the percentage of particles that the filter can remove from the air passing through it.
    What are the benefits of using HEPA filters in cleanrooms?
    HEPA filters provide high levels of air cleanliness by capturing 99.97% of particles 0.3 microns or larger. This reduces contamination risks, protects sensitive processes, and ensures compliance with industry standards.
    How often should HEPA filters be replaced?
    HEPA filters should generally be replaced every 1 to 3 years, depending on the usage, environment, and manufacturer's recommendations. Regular testing and monitoring can help determine the optimal replacement schedule.
    What factors can affect the lifespan of a HEPA filter?
    Factors affecting the lifespan of a HEPA filter include the level of airborne contaminants, airflow rate, operating environment, and maintenance practices. High contamination levels and inadequate maintenance can shorten the filter's lifespan.
    How should HEPA filters be maintained and tested for optimal performance?
    HEPA filters should be regularly inspected for damage, tested for efficiency using methods like the DOP (Dispersed Oil Particulate) test, and replaced as needed. Proper sealing and installation are also crucial for optimal performance.
    Can HEPA filters be used to filter out viruses, including the coronavirus?
    Yes, HEPA filters can capture viruses, including the coronavirus, as they are effective at removing particles much smaller than 0.3 microns. However, for maximum protection, HEPA filters should be part of a comprehensive infection control strategy.
