HEPA filters and DOP testing
HEPA filters and ULPA filters are used in the air purification process associated with ventilation systems. They are particularly important in healthcare critical ventilation systems and the pharmaceutical, microelectronics, optical and aerospace industries, where the supply of ultraclean air is imperative. This could be in, for example, an ultraclean operating theatre, cleanroom, laboratory or isolation room.
The filters work by forcing air through a very fine mesh of densely matted fibres that trap unwanted particles. It is essential that the filters in these sensitive areas are checked regularly to ensure they have been correctly installed and have not developed leaks during operation or installation.
DOP testing is performed in accordance with all relevant guidelines, including BS EN ISO 14644-3 as specified in HTM 03-01 Specialist Ventilation for Healthcare premises.
At all times during the testing, our engineers adhere to strict health and safety procedures and follow manufacturer’s instructions when handling any equipment.
