DOP (Dispersed Oil Particulate) Testing is a procedure to validate the integrity of a HEPA (High Efficiency Particulate Air) filter. Our fully trained engineers can test all types of LEV equipment containing a HEPA filter.
Fumex Ltd only use the very latest calibrated equipment. This includes an Aerosol Generator to produce a sub-micron aerosol to international standards;- BS 5295, ISO 1822, ISO 14644-9 and a state-of-the-art Digital Aerosol Photometer.
The test involves an aerosol of oil particles being drawn into the LEV system or unit, upstream of the HEPA filter. Using a calibrated photometer, we then record any particles downstream to determine the HEPA filter efficiency and this also checks for any leakage of filter seals etc.
With many company insurance policies now stating that all LEV (with HEPA filters) require validation of the integrity of the HEPA, Fumex Ltd can provide a cost-effective DOP Test to ensure compliance to all your policy regulations.
