UNI-FLOW INTEGRATED AIR & LIGHT CEILING

Bacteria cause infection within operating theatres.

In tests carried out by the UK Department of Health “Vertical Laminar Flow Ventilation” was found to reduce the amount of bacteria present in a typical operating theatre by a factor of up to 15,000”.

The UniFlow Integrated Air and Lighting operating theatre ceilings are designed to meet the varying demands of modem surgical techniques.

Modular Integration of the filtration, air diffusion, lighting, and plenum chamber solves the problems of coordination encountered during construction.

Individually tailored to suit the customer’s requirements, Schönn offers a selection of ceilings to suit all surgical applications.

Supplied with optional Air-conditioning and control systems, or as part of an existing mechanical services system, the Schönn range of specialist ceiling reduce the risk of postoperative infection, while providing optimum comfort through the use of conditioned, filtered clean air.

The range of ventilated ceiling has been specifically designed for the application and is ideally suited for today’s surgical techniques.

The range of ventilated ceiling has been specifically designed for the application and is ideally suited for today’s surgical techniques.

Simultaneously solving the problems of coordination, which may be encountered during the construction or refurbishment of the modern operating theatre departments.

The ceiling is available in a range of sizes, the standard being 260 Metres x 2.40 Metres completely integrated within the adjacent false ceiling.

The ceilings consist of a plenum box supplied with conditioned air from the central system via “S” class HEPA filters mounted on the inlet to the supply ceiling. The ceiling can include optional integral lighting and composite air\light diffusers.

All ceiling incorporate supports to secure them to the main structural frame of the modular operating theatre, or structural ceiling slab.

The air\light diffusers consist of a monofilament precision woven polyester bonded to aluminum frames.
The screens have uniform porosity, with an open area of sufficient resistance to create the laminar airflow from the diffuser face.

Diffusing air into the theatres, uniformly over the total are, the mgi range of ventilated ceiling, provide the sterility and cleanliness required in today’s operating theatre environment. Optional integral lighting provides illumination across their total area.

In this way, it is also providing such problems which can hinder the integrity up from the building of the stages of the modern operation theatre time till to using this building.

With its illumination and diffuser variants designed system can meet all of the requirements from the OP Room Staff and it can also offer the customers variants of selections. Laminar Air Flooded OP Room Ceiling are produced in the standard sizes like 2,6 m x 2,4 m but it can also be produced variable to the customer's requirement In bigger or smaller sizes in the condition that the functions will be the same.

The produced Laminar Flow OP Room Ceilings are In exact conformity with the existent suspended ceiling.

System Design below parameter must be controlled.
1-Temperature
2- Humidity
3- Clean Air
4- Particle and Micro-Organism number
5- Atmosphere Air Pressure
6- Air Condition

Regarding the Operation Type, the Temperature of the OP Room can be wished low or high. The temperature of the OP Room must be as below;

DIN 1946/4,1989 22-26 C°.%30 - %65
DIN 1946/4.1999 22-26 C°.%30-%65
DIN 1946/4,2005 figure 19-26 C° can be arranged.


IMPORTANT PROPERTIES OF THE OP ROOM HUMIDITY

Humidity in the OP Room must be adjustable in accommodation conditions and if it is wished.


IMPORTANT FROM THE CLEAN AIR IN THE OP ROOM

The filtered air given to the OP Room must increase the quality of the OP Room air.
Minimum clean air flow must be as below;

DIN 1946/4,1989 1200 m³/h
DIN 1946/4,1999 1200 m³/h
DIN 1946/4,2005 figure 1200 m³/h

 

Operation Room Feeding Air flow DIN 1946/4, 1989, 1999
depends on Temperature decrease or increase
mustn’t be under the 2400 m³/h
for the 1.OP Room Theatres under the name Laminar Flow, must be the air flow 2400 m³/h and the pollution factor 0,67.

The OP Room Theatre air feeding rate 2005 figure, must be for OP Rooms Operation table, instruments and operation materials must be lower than linear flow.

This is approximately equivalent to 3x3 m², and it is changing to OP types.
Linear air flow capacity must be higher then 0,23 m /sec.

 

SPECIFICATION
The ceilings consist of a plenum box supplied with conditioned air from the central system via “S” class HEPA filters mounted on the inlet to the supply ceiling.
The ceiling can include optional integral lighting and composite air/light diffusers.
All HEPA filters and housings are factory tested and certified.
All ceilings incorporate supports to secure them to the main structural frame of the modular operating theatre,or structural ceiling slab.
The air / light diffusers consist of a monofilament precision woven polyester bonded to aluminum frames.
The screens have uniform porosity, with an open area of sufficient resistance to create the laminar airflow from the diffuser face.
Uniformly diffusing air into the theatres, over the total area, through the mgi range of ventilated ceilings provide the sterility and cleanliness required in today’s operating theatre environment.
Optional integral lighting provides illumination across their total area.
Lighting is generated from high-frequency electronic ballasts; complete with color corrected fluorescent tubes ensuring a comfortable, shadowless working environment.
