DOP Filter Testing

An integral part of your specialist ventilation system, high efficiency particulate air (HEPA) filters require regular maintenance and validation, and DOP filter testing plays an essential role in this. DOP testing forms a part of the regulatory requirements for operations relying on specialist ventilation and needs to be carried out in a consistent way by experts to ensure reliability.

BAS engineers carry out DOP filter testing to industry standards to ensure clean rooms and other specialist or critical environments are operating to the highest standards.
Within your specialist ventilation system, your high efficiency particulate air (HEPA) filter works to remove fine powder and dust from the environment, providing particulate free, clean air in its place. DOP filter testing is used to determine whether these filters are performing to the standards deemed acceptable by your regulatory bodies, keeping your operations running smoothly.

Using a cloud of dispersed oil particulate as an aerosol, DOP testing involves releasing a high concentration of the aerosol into the airstream, upstream of the filter. Measurements will then be taken to ensure that no seepage has occurred, either through the filter itself, or through its casing.
DOP filter testing provides assurances for all parts of the filter, including the seals, the housing of the filter, and the joints onto the duct work itself. During the test, a check is also made to ensure that all of the air within the clean room is passing successfully through the filter, ensuring there are no dead spots where contamination can build up.

Involving highly specific and technical guidelines to ensure consistent testing, as well as being a part of your regulatory obligations, the DOP testing for your specialist ventilation system should be carried out by professionally qualified engineers to avoid costly mistakes.

As well as having the correct equipment, and the training to use it, to carry out the task effectively your DOP filter tester will require a full understanding of BS EN ISO 14644-3 (B.6), current Good Manufacturing Practice (GMP) and a sufficient level of experience to be able to problem solve any leakages identified.
