A micron is the unit we use to measure particulate. One micron is equal to one-thousandth of a millimetre. The smallest particle the human eye

This depends on what you are trying to protect. Positive pressure cleanrooms protect the process inside the room from any particulate outside the room. Negative

We would advise that you maintain around 30 pascal of positive pressure inside your cleanroom and 15 pascal in your gowning room. Maintaining this level

Maintaining the correct pressure levels is fundamental to the function of the cleanroom. If the pressure is too low contaminants can enter. A magnahelic pressure

There are many different ways of describing an ISO 14644-1 class 5 cleanroom. These can include; ISO 5 cleanroom, grade 5 cleanroom, ISO 5, class 5. ISO

Laminar Air Flow. ISO 5 (Class 100) and cleaner facilities rely on unidirectional, or laminar, airflow. Laminar airflow means that filtered air is uniformly supplied in

The filter condition gauge or minihelic gauge is measuring the differential pressure between ambient and the HEPA filter. This pressure reading will increase over time

In order to control the particulate levels in your cleanroom, operators must wear appropriate cleanroom garments and follow strict cleanroom protocols whenever working in or around a

All cleanrooms over ISO 8 require an area where a gowning protocol can be enforced. In the gowning room it is usual to find a step over bench with

Products and materials that are subject to shedding or particulate generating should be banned from the controlled area e.g. cardboard, wood, and mild steel products that
