Clean rooms
Operating rooms and laboratories are complex systems with extreme hygiene requirements for materials and equipment.
It is very important to ensure laminar air flow to avoid infection during surgery. When we supply air into the room from laminar units, we must keep low noise level.
A high level operating room requires tight structure. Infection can be avoided if we keep the room overpressured. To ensure clean air we need to filter out particles with high efficient filters in the air terminal.
Diffusers in operating rooms
Supply ceilings with built-in HEPA filters are used for clean rooms where air cleanness as well as intensive air-exchange is required. They are constructed to be built in suspended ceilings of operation rooms, intensive care premises and other clean rooms.

Air flow control
The operating theatre should be ventilated throughout the day. We need to maintain stable air supply air, whch requires VAV dampers that provide stable air flow regardless of changes in the ductwork.
VAV dampers require sound attenuation because dampers have self-generated noise.
Pressure control in the room
A high-level operating theatre requires a tight structure. Infection can be avoided by keeping the room pressurized. Pressure control units adjust the extract air flow by measuring pressure difference between rooms.

Air handling in clean room
Hygienic type air handling units are applicable in hospitals, food industry, pharmaceutical industry and other clean room applications. Characteristical is the construction without grooves and sharp edges, all components and materials are corrosion resistant and resistant to disinfectants. To ensure a high level of cleanness and to prevent growth of microorganisms, all seals are smooth, abrasion-resistant and closed-pore.
Main features:
• Construction without grooves and sharp edges;
• all functional elements (fans, coils, heat recovery units,humidifiers …) are easy removable for maintenance, cleaning and service;
• all used elements are corrosion resistant;
• all components and materials are resistant to disinfectants;
• seals are smooth, abrasion-resistant, closed-pore;
• build-in components are tested and recognised as effective in accordance with the list of the Robert Koch Institute (RKI) or the disinfectant media list of the Association for Applied Hygiene (VAH).
