Clean room which places need to install differential pressure gauge

The purpose of installing differential pressure table in clean room is to observe the difference of air pressure between two different levels of areas, in order to regulate the ventilation pressure of each area, to ensure that the direction of air flow, to prevent the low cleanliness of the air to the high level of regional flow, therefore, the location of the installation of differential pressure table is mainly in the following places: clean area with different requirements for cleanliness, and isolation of the region's isolated wall; transfer window or door; clean area and non-clean area of the separation wall, etc., the installation location to facilitate observation is appropriate. Wall; transfer window or door; clean area and non-clean area of the isolation wall, etc., the location of the installation in order to facilitate the observation of the appropriate, generally required to visit the channel also requires the addition of the relevant micro-pressure difference table.
