  • Aerosol generators for HEPA filter & ULPA filtration tests

  • Smoke generators for Filter Integrity Testing (DOP)
  • Air flow Visualisation testing / Particle recovery work

The correct functioning of HEPA filters is normally tested at the time of installation, as well as part of the routine maintenance programme. It is normally recommended that HEPA filters are checked at 14 month intervals or less, or immediately after filter changing. Where high efficiency filters are fitted, it is vital that the filter housing/sealing device does not allow particulate material to pass and thereby compromise the cleanroom environment that is being served. Testing is necessary since HEPA filters can become partially or totally blocked, rendering the filter of little value.

The Filter Integrity Test, which uses smoke as a detection method, is usually referred to as a DOP test. This is because the original smoke chemical used for this test was made using  Di-Octyl Phthalate. However, as this substance was suspected to be a carcinogen, pharmaceutical grade white mineral oil is now used with identical results.

The new smoke and aerosol generators in Concepts "Cleanroom Solutions" range are used throughout the world by major blue chip pharmaceutical, nuclear and cleanroom specialists for their HEPA filter, ULPA filtration testing, air flow visualisation work and particle recovery tests.

For Air Flow Visualisation and particle recovery work, our portable, water based MiniColt 4S generators are ideal as they enable the tester to move from one part of the room to another, making smoke, in order to ‘see’ if the flow of air is correct, this system can also be ducted.

Concepts BS EN ISO 9001:2008 scope is - "Design, manufacture and supply of non-toxic smoke generating equipment and aerosol generating equipment for scientific, military, security and industrial use.

Over the years Concept have designed and manufactured many "specialised" projects, so let us know if you have any unique requirments.
