HEPA & ULPA filters | Camfil
Absolute V HEPA Efficiency: 95% to 99.999% at 0.3. Media: Microfine glass media formed into individual mini-pleat media packs and assembled into a V-bank filter configuration. Recommended final pressure drop: Consult factory. Rule of thumb: change filter when the initial pressure drop doubles.
DOP Testing | HEPA Filter Validation | Tecomak Environmental
Filter management services (storage and routine replacement) HEPA (High Efficiency Particulate Air) filters are devices which remove solid particles such as dust, pollen, mold, and bacteria from the air. They are used to remove ultrafine dust, aerosols and viable organisms.

High Performance HEPA Air Filter With DOP Feature： 1.High efficiency 99.995% on 0.3 microns 2.Light weight and easy to install, High holding capacity 3.Aluminum alloy frame, anodized surface, air inlet and outlet with spray-paint metal protection net
DOP Testing For Cleanrooms | Modular Cleanrooms By Total
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.
HEPA Filters Cleanrooms | Modular
This HEPA filter system is rated at 99.999999+% DoP and the result is a higher class cleanroom with superior clean air. In addition, this filter exceeds most international standards and best practices and has enough power for double HEPA filtration air re-circulation and exhaust.
- What is the difference between a HEPA filter and a DOP filter?
- 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.
- What is a HEPA filter used for?
- HEPA filters are used to provide clean air for cleanrooms in industries such as pharmaceuticals, biotechnology, medical devices, semiconductor, manufacturing and nuclear technology. Multiple pleated layers of filter media player are used in the construction of the HEPA filter. It prevents particles from getting past the filter.
- What is a DOP filter?
- 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.
- What liquids are used in a DOP filter test?
- Other liquids used include DEHS and paraffin oil. DOP filter testing provides assurances for all parts of the filter including the filter housing, the seals and the joints. A check will be made during the test to determine if the air in the cleanroom successfully passes through the filter.
- What is a HEPA filter media player?
- Multiple pleated layers of filter media player are used in the construction of the HEPA filter. It prevents particles from getting past the filter. Instead, they stick to the filter fibres after becoming trapped. An annual output test is conducted to ensure that aerosol meets distribution criteria.
- What does a HEPA filter photometer measure?
- 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. The generator is used to produce aerosol which is introduced to the airstream and passed to the HEPA filter for testing.
