The laminar flow ceiling in the operating theatre ensures a low bacterial index in the surgical area and in the supply airflow due to the laminar flow replacement flow. In the anaesthetic area, the concentration of harmful gases is also low.

The minimum requirements of DIN 1946 part 4 are now exceeded. Inspections by health experts of OR laminar flow ceilings that have been incorporated into air treatment plants have confirmed extremely low contamination levels.

1. Laminar Flow Ceiling is widely used at operating room and laminar flow as final filtration system. It has the effect of a high efficiency filtration, current and airflow compensation function.
2. Yaning series clean air ceiling is the crystallization of the experience and practice of the operating room supplying air. This air supplying has been put into use of verification of nearly 1,000 operating rooms. Its superior performance and unique diffuser can evenly sent the air to the work area. The central flow compensation device can effectively eliminate the heat generated updraft of laminar flow of the energy equipment.
3. The Yaning Laminar Flow Ceiling is leading a domestic and foreign resistance drain layer technology. The use of this equipment can be a reasonable distribution of clean room airflow, and to effectively guarantee the indoor cleanliness.

It is mainly used in the hospital operating room to meet the requirements of different operating levels.
