Contact SupplierWhat Is DOP Testing?
DOP testing is the process where the integrity of your High Efficiency Particulate Air (HEPA) filter is tested by introducing Dispersed Oil Particulate (DOP). The filters are used in industrial equipment items such as fume hoods, negative air units and powerful vacuums. They protect the environment and humans from harmful substances in the air such as asbestos, bacteria and hormones by filtering out 99.97% of particulates, up to 0.3 microns in size.
The HEPA filter works within your specialist ventilation system to remove dust and fine powder from the environment and provide clean air that is particulate-free. A DOP filter determines if the filters are performing up to the standards set by regulatory bodies to ensure smooth operations.
Oil is dispersed as an aerosol into the filter mediums’ upstream flow. In the downstream flow, the number of particles is measured with a calibrated photometer. Due to the fact that cleanrooms often protect mission critical environments, DOP testing is essential. The entire filter face is tested to detect leak or damage.
DOP Filter Testing Equipment
Aerosol Photometer
Saakvee Technologies uses an innovative, advanced and digital aerosol photometer to to perform DOP tests. We have portable DOP testing machines guaranteed to maximise efficiency and minimise downtime.
The photometer measures the amount of aerosol downstream and upstream of the filter. The result shows the performance of the HEPA filter. It also reveals damages or leaks in the seals, frame and mediums.
Aerosol Generator
The generator is used to produce aerosol which is introduced to the airstream and passed to the HEPA filter for testing. An ancillary equipment is used to inject, mix and test the aerosol such as injection ports, positive injection pumps, sample ports, sparge pipes and scanning probes.
Our aerosol generators are lightweight, portable and rugged. They are ideal for testing different filter systems by generating sub-micron, poly-dispersed aerosol. Applications include negative-pressure filtration units, workstations, ceiling modules, biological safety cabinets and more.
When To Do A DOP Test
Equipment with HEPA filter should be tested when it will be used for a new project or moved. Filter seals could become loose due to ill use, causing leaks and making the equipment unsafe for workers.
For the same project, it should be tested every four weeks and onsite for best results. This ensures the HEPA filter units have not been damaged by daily onsite activities or during transportation.
Why Have A DOP Test?
Without a DOP test, there is a high risk of contamination to your cleanroom. It could impact your product quality and processes which in turn affect your cleanroom certification. A DOP test saves money, time, reduces cost product recalls and prevents damage to your brand.
Saakvee Technologies has CTCB certified engineers who have had at least 5 years of experience before sitting the certification exam.
