The laminar air flow moves in a uniform straight line, and the air enters the chamber from the filter with a coverage rate of 100%. The air is returned by the elevated floor or both sides of the partition board. This type is suitable for clean room for higher environment use, generally the cleanroom class is Class1~100. The type can be divided into two kinds:

(1) horizontal laminar flow: horizontal air self filter is blown out in one direction, the return air from the opposite wall, return air, dust and wind are discharged outside, and the pollution on the lower side is more serious.

Advantages: simple construction, after a short period of time can become stable.

Disadvantages: construction costs than high turbulence, the interior space is not easy to expand.

(2) vertical laminar flow: the ceiling of a room completely with ULPA filter cover, air blowing from the top down, can get higher Zhijie clarity, resulting in process or staff can quickly exhaust the outdoor dust and will not affect other work areas.

Advantages: easy to manage, operation start short, the time can reach the stable state, not easy for the operation state or the operator.

Disadvantages: the construction cost is higher, the flexibility of the use of space is difficult, ceiling hanging space, maintenance, replacement filter is more troublesome.
