100 clean room belongs to a relatively high cleanliness level and is generally used for products with high environmental requirements. In order to achieve a 100-class clean room, the purification equipment used is also special. Usually, the ceiling of the workshop is covered with FFU to purify the air. Because FFU is vertical flow, it is necessary to lay an elevated floor with holes at a suitable height on the workshop floor, and introduce the air treated by the high efficiency filter (FFU) at the top of the clean room vertically into the rear part below the floor.
If the workshop height is not enough to ensure that there is no extra height after the ceiling height, then it is also possible to appropriately reduce the height of the elevated floor. On the other hand, if people want to enter the raised floor conveniently for cleaning, the height of the raised floor can also be designed to be higher. Therefore, in fact, the height of the elevated floor of the 100-level dust-free workshop does not have a fixed height, which needs to be designed according to the specific situation.
