What is DOP Filter Testing?
We often get asked what is DOP (dispersed oil particulate) Filter Testing?. In most specialist clean room ventilation systems, there will be a high efficiency particulate air (HEPA) filter. This works to remove fine powder and dust from the environment, providing particulate free, clean air in its place. A DOP HEPA test is used to determine whether these filters are performing to the standards deemed acceptable by your regulatory bodies, keeping your operations running cleanly and smoothly.
DOP testing involves releasing a cloud of dispersed oil particulate as an aerosol into the airstream, upstream of the filter. Measurements can then be taken to ensure that no seepage has occurred, either the filter casing/housing or through the filter itself.
Hepa Filter integrity 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 Hepa Filter 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 is minimal contamination build up due to dead spots etc.
As well as being a part of your regulatory obligations, the HEPA filter testing for your specialist ventilation system should be carried out by qualified engineers to avoid costly mistakes. We are fully trained using the latest equipment to carry out your DOP filter test. Also, due to our air leakage experience and construction design experience we can quickly identify any potential air leakage paths as part of your clean room testing programme.
