What is a ceiling laminar air flow system ?

Laminar air flow ceilings provide effective protection against contamination caused by airborne dead or living particles during invasive acts. Ceilings are available in square or rectangular shapes to accommodate any room layout and specific requirements for creating a clean zone around the patient, medical staff, and medical devices.

Aerobiologically, the staff are the source of the majority of airborne contamination in an operating room. On an airborne skin scale, the most common unit of contamination (colony forming unit – “cfu”) is a microcolony. There will be between 1 and 1,000 bacteria in that microcolony. (Microbial numbers are an important factor in infection initiation.)

One important function of operating room ventilation is to keep airborne bacteria from settling in “the wound.”

Our laminar flow ceilings are primarily used with our Clinicair Air Handling Unit, but they can also be adapted to any other brand’s products. This system is intended for use in operating rooms to meet ISO 5 standards (complying with EN ISO 14644-1) as well as in the pharmaceutical industry. It aids in the prevention of cross-contamination and hospital-acquired infections.

Ceiling Laminar Air Flow

Cabinet material: Cold rolled steel with powder coated / Stainless steel.
Efficiency: 99.99%@0.3μm
Advantage: Applying leading resistance drain layer technology which allows reasonable airflow distribution inside clean room , effectively guarantee the indoor cleanliness.


1. Leading domestic and international technology
The BIOAIRO Laminar Flow Ceiling is at the forefront of domestic and international resistance drain layer technology. The use of this equipment can provide a reasonable distribution of clean room airflow while also effectively ensuring indoor cleanliness.
2. The assertion of effects and functions
The BIOAIRO series clean air ceiling is the culmination of operating room air supply experience and practice. This air supply has been used in nearly 1,000 operating rooms for verification. Its superior performance and unique diffuser can distribute air evenly to the work area. The central flow compensation device effectively eliminates the heat-generated updraft of the energy equipment’s laminar flow.
