  It includes Laminar (Vertical and Horizontal), Turbulent, Mixed and Tunnel; consider characteristics of each type and the purpose of use for selection.

  The cleanliness level of clean room is determined by the degree required for each product. You must fully check air flow, number of ventilations and indoor pressure.

  The layout must meet characteristics of task and the cleanliness level. Any task causing much dust should be separate from other tasks and consider completely entry, pass, utility, maintenance, etc.

  The internal surface should be smooth so that the air flow cannot be dispersed or dusts cannot be built. You should use materials which cause little dust; particles are not well attached to; and allow an easy cleaning.
Chemical-, humidity-, or fire-tolerant materials may be used depending on tasks.

  Equipments consisting of a clean room include air shower and pass box for removing dusts; relief damper for keeping pressure; and clean stocker and clean locker for storing goods or packing. You must fully understand functionalities of each item.

  Working persons and materials incoming from the outdoor are the primary cause of dust. Working persons must have basic knowledge about clean room, including dust-free garment and the matter of make-up.

  The system to provide energies including water, gas or electricity should be selected based on the type of airflow and flexibility of layout. A careful attention is required for maintenance not to cause a decrease of the cleanliness level.

 

A clean room is a closed structure so requires measures against fire or gas leakage. An emergency power facility should be considered in equipments that can meet any problem by blackout.
