Fact: 11,527 miles of ductwork cleaned and counting

Pharmacy aseptic units are used to prepare treatments in an environment that is free from bacteria. Products are prepared within a pharmaceutical isolator which has its own sterile airflow. They vary in size and complexity, and are used extensively in industries such as semiconductor manufacturing, pharmaceuticals, biotech, medical device and life sciences, as well as critical process manufacturing common in aerospace, optics, military and Department of Energy.

We are not associated with any manufacturers or suppliers of equipment. We can provide a completely unbiased report on the performance achieved, and are also able to service multiple systems from multiple suppliers in the same visit. Ensuring regular maintenance and conducting preventative maintenance will reduce the incidence of plant failure and production downtime, keeping your operations running smoothly

Our engineers are fully trained in cleanroom maintenance and have a sound understanding of the requirements of BS EN 12469 and GMP. All instruments used in testing are calibrated to national standards and copies of certification are supplied with reports

  • Supply and extract air change rates

  • Room pressure differentials

  • Light level test

  • Sound level test

  • Room schematic
