Operating Theatre - Clean Room Ventilation
During an operation human life must be safeguarded to avoid contamination from the surrounding area.
Safeguarding human life at it's most vulnerable
To understand HVAC solutions within an operating theatre we must first be aware of the varirty of risks. Our specialist hospital ventilation solutions have been developed to meet the specific needs of this application type.
During an operation contamination can come from 2 main sources.
- Engogenous, which essentially comes directly from the patients skin or body matter; or from an infected prosthesis or implant.
- Exogenous, which comes from the surrounding environment or surgical staff and their equipment.
The understanding of the above leads us on to consider such things as direct and indirect contamination. Direct meaning items that will directly be place in contact with the patient during surgery such as surgeons hands and instruments. Indirect is therefore contamination which might come from dust in the air, droplet nuclei, even the fibres in clothing or airborne infectious diseass.
Contamination Control
- Supply air needs to be filtered in three stages with a HEPA filter at the third stage
- Low turbance airflow above the operating table (almost laminar)
- Overpressure to the neighbouring rooms needs to be maintained at ca. 15Pa
- All surfaces inside of the room should be smooth and easy to clean – rounded corners, reduced numbers of joints
Clean Room Technology by FläktGroup
Numerous international manufacturers work with FläktGroup‘s Clean Room Technology as a result of our expertise in developing reliable and effective contamination control methods for Clean Rooms.
Clean Room solutions from FläktGroup permit users to coordinate all critical parameters precisely with the requirements of respective production processes and to systematically control decontamination of room air. These solutions control air pressure, temperature, and moisture – especially the contamination with fine dust, skin particles and bacteria – and keep these contaminants away from products and processes.
Effective and precise clean rooms design is essential for semiconductor production and pharmaceutical industries, as well as companies in the chemical industry, space technology, and optics and laser technology perform research and production; where we see that conditions in these industries are increasingly relying upon Clean Room conditions.
Technical, chemical, and biological quality products with highly sensitive manufacturing processes are further processed in hermetically sealed areas that demand room air that is virtually dust-free. The manufacturing process itself, however, requires ambient air absolutely free of particulates.
Our Process
We offer a full portfolio of support every step of the way from 3D design to installation, to reports in order to develop your bespoke project.
With decades of experience in clean rooms, we bring the necessary expertise into your project and help you to create an optimal concept for the clean room, which is energy efficient and reliable.
Once the clean room layout is finalized, we create a 3D model with all little details – to the last screw.
For you to check – and for our production.
All our factories work with the 5S approach and have a best-in-class on-time delivery rate.
In our modern facilities we produce fast standardized products, but are flexible to support you with customized solutions.
The installation is a crucial part in the process. Especially for a clean room. Hence, we have very well trained teams in our core countries. Everywhere else, a supervisor from the factory will be present during the whole installation phase.
We support the finalization of your project by bringing in our long-term partners. You will get a full report, which is complying to all global and local regulations and standards. And – of course – you can be ensured, that your clean room will operate as required.

CEILINGS
LS Light ceiling (clip-in) features a lightweight construction, although overpressure in a clean room up to 50 Pa is possible. This ceiling has an absolutely flat surface, as the suspending elements are hidden above the modules and enables easy cleaning. LS Light Ceiling consists of a double-layer load-bearing grid with an axial span of 600 x 600, 625 x 625 or 675 x 675 mm. The top and bottom layers of the grid are made up of locking profiles (clip-in solution) and are connected to each other using fixing lugs. LS cassettes made from 0.5 mm thick galvanized steel sheet, finished on the visible side with a 25 μm thick polyester semi-matte paint RAL9010, are inserted into the bottom locking profiles and, along the perimeter ofthe room, into aluminum end profiles (profile F, radius profile RF). Joints are sealed with silicone. KS Cassette ceiling (grid) is designed for higher classes of clean rooms and feature a rigid construction. This allows high over and under pressure in a clean room. A characteristic feature of the KS ceiling is the grid made of KSL profiles, visible from the room level. The cassette ceiling (KS) consists of a load-bearing grid made from aluminum KSL profiles, with an axial span of either 1380 x 690 mm or 690 x 690 mm. The KSL profiles, coated in RAL 9010 varnish, are connected to each other using KSL couplers. KS cassettes are made from 1.0 mm thick galvanized steel sheet, finished on the visible side with a 25 μm thick polyester semi-matte paint (RAL 9010). KS Cassettes are integrated with the grid structure from the top (secured by KSL clamps), and along the perimeter of the room, Finish-cut Cassettes are inserted into aluminum end profiles (profile F/radius RF/radius R30+L30x20). Joints are sealed with silicone KSH Alucore ceiling (grid) with honeycomb aluminum cassettes (Alucore) and a robust design, the KSH ceiling can bear a load of 150 kg/m², allowing for walkable access from above. KSH ceiling consists of a load-bearing grid made from aluminum KSL profiles, with an axial span of either 1280 x 690 mm or 655 x 690mm. The KSL profiles, coated in RAL 9010 varnish (RAL 9003 on request), are connected to each other using KSH couplers. KSH cassettes are made of sandwich panels performed in Alucore material (honeycomb aluminum structure) with a thickness of 10 mm. Cover sheets are made of aluminum alloy and the sheet core is performed as aluminum honeycomb. Both sides are platinum white with a polyester paint (approx. RAL9003). Cassettes are integrated with the grid structure from the top (secured by KSH clamps) and, along the perimeter of the room, are cut to fit into KSLprofile, which is fastened to strip L30x20 and covered by aluminum radius profile R30. Joints are sealed with silicone.
