UCV Systems are designed for busy Operating Theatres. They can be individually designed to work with varying types of pendants and include lighting, return/recycled air. The UCV incorporates the AES range of HEPA filters and accessories, they can be either gasket seal or gel seal. Previously acceptable levels of up to 500 bacteria-carrying particles per cubic metre are reduced to less than 10 particles by cubic metre by the UCV (Ultra Clean Ventilation) system, with obvious health and financial benefits to your patient and the hospital.
Produced as a modular system by Australia’s leading manufacturer of air filters and laminar flow systems, the UCV is easily retrofitted to the ceiling or within the ceiling void of existing operating theatres. A controlled column of ultra clean air is delivered down over the operating table, your surgical team and their equipment. It then moves radically outwards and up to the return air intakes. Your team has free access to and from the operating zone without the risk of introducing dirty air from outside. Keeping the Operating Theatre Ultra Clean.
The design of a partial walled Ultra Clean Air System should take into consideration of the entrainment from the room air into the clean zone air, air velocity at the operating table and the temperature difference between supply and room air. In operating theatres where deep wound surgery takes place, the ultra-clean air ventilation systems should achieve the following minimum standards:
| Parameter | Specification |
| Overall size of ceiling module with built in recirculating fan | 3800×3800 |
| Size of clean zone | 2780×2780 |
| Depth of unit below ceiling (variable) | 60mm min |
| Supply air volume (normal airflow) | 2.9401 m³/sec |
| Average downflow velocity at lower canopy edge | 0.38 m³/sec |
| Approx. room air change if air supplied into UCV | 100x per hr |
| Filtration standard | Final filters: 99.999% on HOT DOP to AS4260; Prefilters: 85% to AS1324 (No.4 Dust) |
| Electrical rating (high speed, including fluorescent lights) | Single phase, nom 3.9kW |
Materials: Plenum zinc seal (zincanneal) steel, finished with a laboratory grade coating that is solvent, alkali and acid resistant to provide a durable and easily cleaned surface finish. The diffuser is constructed from perforated stainless steel which assists with the distribution of airflow.
Fans: Variable speed direct drive centrifugal fan/blowers enable airflow adjustment throughout the filter life and allow adjustment of the supply air velocity.
Silicone Gel Sealing: The filters are sealed in place by a unique two-part silicone gel designed to create and preserve an airtight seal between the filter and the filter housing. The gel is factory installed and factory cured in the filter frame. Once cured, it has the self-healing qualities of a liquid while retaining the stability and non-flow characteristics of a solid. The risk of air bypass from conventional gaskets and seals is effectively eliminated.
Filters: HEPA or high performance ULPA filters with unique fluid seals. Medium-efficiency disposable pre-filters are fitted behind the hinger return air grilles to extend the life of the main filter. All filters are individually tested in strict accordance with the requirements of Standards Australia and the performance of the pre-filters and final filters is continuously monitored by Magnahelic differential pressure gauges.
