DOP Testing H Class Vacuum Cleaners & NPUs

DOP Testing H Class Vacuum Cleaners & NPUs

DOP testing is a method used to evaluate the efficiency of high-efficiency particulate air HEPA filters, including those used in negative pressure units (NPU) and H class vacuum cleaners. HEPA filters are designed to trap extremely small particles, including dust, pollen, mold, asbestos fibres and bacteria, making them highly effective in improving air quality.

DOP testing using an aerosol photometer and aerosol generator is also required to meet numerous local and global standards including the Australian standard (AS/NZS 60335.2.69:2017) relating to H class vacuum cleaners.

While DOP testing is commonly referred to on this page, all of our photometers are typically used with non carcinogenic PAO (poly Alpha Olefin) which is available through Alpha Scientific in Australia.

Why DOP Testing

DOP testing is important for testing HEPA filters on vacuum cleaners for several reasons:

Performance Verification

DOP testing verifies whether the HEPA filter meets the required efficiency standards. It ensures that the filter can effectively capture particles, enhancing the overall performance of the vacuum cleaner.

Health and Safety

HEPA filters are essential for trapping harmful particles, especially for individuals with allergies, asthma, or respiratory conditions. Ensuring that the filter functions as intended is crucial for maintaining good indoor air quality and protecting the health of the users.

Compliance

In Australia, certain types of HEPA filtered vacuum cleaners are required to be DOP tested regularly to ensure compliance with the latest AS/NZS 60335-2-69 standard. Alpha Scientific offers test systems which allow companies test to this standard.

Quality Control

DOP testing is a quality control measure that helps manufacturers identify any defects or issues with the HEPA filters before they are installed in vacuum cleaners. This helps in maintaining consistent product quality and customer satisfaction.

Accreditations & Calibrations

Our precision aerosol photometers, aerosol generators and related products are manufactured by Junray based in Asia. Founded in 2007 and with other 300 employees, Junray has grown to become a world leading global manufacturer of aerosol photometers, aerosol generation equipment, cleanroom monitoring, particle counting and many other state-of-the-art products.

Junray is also the most highly accredited manufacturer of photometers and related products and was the first photometer manufacturer to gain both ISO 9001 & ISO 17025 accreditation long ago. All our photometers come supplied with (at no additional cost) an ILAC-MRA / CNAS calibration certificate (equivillant to NATA) and they are fully serviced, supported and NATA calibrated in Australia.

  • ISO 9001: 2015 Quality Accredited
  • ISO 14001:2015 Environmental Management System Accredited
  • ISO 45001:2018 Occupational Health & Safety Accredited
  • ISO 17025 Testing & Calibration Accredited
  • ILAC-MRA CNAS Calibration Certificate Included, optional NATA in Australia
  • CE Certified

DOP testing is vital for testing HEPA filters on vacuum cleaners and negative pressure units (NPU) as it ensures their efficiency in capturing small particles, thereby promoting better air quality and user health while ensuring compliance with industry standards and regulations.

Aerosol photometers are devices used for testing and evaluating the performance of filters, particularly those used in air filtration systems. These photometers measure the upstream and downstream concentration of airborne particles, allowing for the assessment of filter efficiency and performance.

Aerosol Photometers & Standards

  • AS 1807:2021 Australian standards
  • ISO 14644-3:2021 Cleanrooms and associated controlled environments – Part 3: Test methods
  • NSF/ANSI 49-2024 Biosafety cabinetry
  • BS EN 12469:2000 Microbiological safety cabinets
  • GB 50591-2010 Code for construction and acceptance of cleanroom
  • 2010 GMP for pharmaceutical products-plant and equipment
  • IEST-RP-CC034 Hepa & Ulpa Filter Leak Tests
  • JJF 1800-2020 Calibration specification for aerosol photometer
  • JJF 1815-2020 Calibration specification for class II biosafety cabinet
  • AS/NZS 60335.2.69 Testing H class vacuum cleaners

Aerosol photometers are also commonly used by testing and certification companies, HEPA filter manufacturers, cleanroom operators and many other organizations. They may be used with or without aerosol generators to make accurate and reliable measurements.

Particle counters, ventilation test instruments and other equipment sold by Alpha Scientific is also commonly used by many of these organizations.

Note: While DOP testing is commonly referred to on this page, all of our photometers are typically used with non carcinogenic PAO (poly Alpha Olefin) oil which we can supply and is available through Alpha Scientific.
