Integrity testing of HEPA filters - Cleanroom technology
The first in situ HEPA filter test method in the ISOEN14644-3 standard is the traditional aerosol photometer test method. This is commonly known as the DOP test and uses the aerosol photometer as the measuring device and an aerosol generator to produce an aerosol challenge.
DOP/PAO Testing of HEPA Filtered Equipment - Hazmasters
A process that challenges HEPA filtered equipment to ensure it is safe to use in hazardous environments. An aerosol generator is used to convert DOP or PAO oil to an aerosol with particle sizes down to .3 micron. A photometer then measures the amount of particulates in the exhaust air stream. DOP/PAO HEPA testing is key
CMI: Filter integrity testing - aerosol photometer and generator
CMI sells and rents aerosol generators and portable ATI (Air Techniques International) photometers designed for many applications in the pharmaceutical, biotechnology, healthcare, nuclear and dismantling industries as well as for use by professionals working with asbestos and asbestos removal. Following the acquisition of DOP SOLUTIONS in 2016

DOP Testing Procedure - Air Techniques International
DOP / PAO TESTING GUIDELINE 7 | P a g e Step 8 Labeling of machine as a pass DOP/PAO Test (HEPA Filter achieves 99.97% efficiency) and hard copy documentation must be completed and provided to customer as noted in Appendix I. Step 9 For equipment that fails the DOP/PAO Test, no labeling is required and deficiencies
- Which ri8401 thermal aerosol generator is best?
- The Rigel RI8401 Thermal Aerosol Generator is the perfect choice to test and validate all kinds of areas. This is the smallest and lightest aerosol generator on the market. Plus, having a easy-drainable tank due to a valve located at the bottom makes this unit the most practical unit you can work with.
- Who sells aerosol generators & ATI photometers?
- CMI sells and rents aerosol generators and portable ATI (Air Techniques International) photometers designed for many applications in the pharmaceutical, biotechnology, healthcare, nuclear and dismantling industries as well as for use by professionals working with asbestos and asbestos removal.
- Are ATI oil reagents FDA regulated?
- ATI oil aerosol reagent products are suitable for government, nuclear, and FDA-regulated testing applications. Four-centistoke PAO (Chemical Abstract System ID 6864 9-12-7) reagents offer a U.S. Food & Drug Administration-approved alternative to DOP in FDA-regulated filter leakage testing applications.
- What products are available for a polydispersed aerosol filtration system?
- Also available in the range: dilutors to reduce the pressure and concentration of polydispersed aerosol (eg integrity test of filters made with a particle counter), positive injection pumps, fixed injection ports, and of course PAO-4 (EMERY 3004), DEHS and Ondina synthesis oil.
- What is a 5D thermal aerosol generator?
- The 5D Thermal Aerosol Generator is designed for operators who require a wide range of aerosol output concentrations to perform leak tests on smaller clean air cabinets through cleanroom air handling systems. Save time and money in the most demanding multi-filter cleanroom installations.
- What is the smallest and lightest aerosol generator?
- This is the smallest and lightest aerosol generator on the market. Plus, having a easy-drainable tank due to a valve located at the bottom makes this unit the most practical unit you can work with. The RI8401 has the ability to start the generation with a remote control (optional).
