Dispersed Oil Particulate (DOP) Testing

Envirochem now offer on-site Dispersed Oil Particulate (DOP) Testing.

High Efficiency Particulate Air (HEPA) filters are designed to remove fibres and particles from the environment.

HEPA filters require regular maintenance and validation.

DOP testing is an essential part of this and is used to determine if the performance and integrity of the HEPA filter is of an acceptable standard, identifying if there are any leaks present within the filter, frame or seals.

All equipment containing HEPA filters (e.g. Negative Pressure Units and ‘H’ Type vacuum cleaners) must be tested every 6 months, and if the filter has been replaced or the equipment has been dropped or damaged in any way.

As part of a DOP test, Portable Appliance Testing (PAT) and air flow testing is required. Once tested, a certificate is issued and each piece of equipment labelled.

Minimum charges will apply, please enquire for further information.
