Halton Vita VHR is a HEPA diffuser with integrated disinfection units for spaces where high cleanliness levels are required. Integrated blue light technology provides a chemical-free disinfection method for surfaces to ensure a safer working environment. Disinfection units also include white light LEDs for general lighting.
The Halton Vita VHR diffuser can be used both for supply and exhaust air.
In the supply application, the diffuser supplies the filtered air into the space through adjustable nozzles. The nozzles can be adjusted in 15-degree intervals, which makes it possible to create the desired airflow pattern.

In the exhaust application, the air is exhausted through the perforated front panel and filtered before it flows to the ductwork.

Disinfection units can be integrated into the product. Each unit has both blue light and white light LED elements. The blue light LEDS are used for surface disinfection and the white light LEDs for general lighting.
The ability of blue light to destroy microbes is based on its ability to energise naturally light-sensitive compounds found in all bacteria, yeast, and mold cells. When these compounds are exposed to high-intensity blue light, a natural chemical reaction starts where free oxygen radicals are formed inside cells. These free radicals are highly reactive molecules that start destroying the cells from within by damaging their internal structures. When continued long enough, the reaction destroys the microbes.
The integrated design of disinfection units provides optimised disinfection over the whole operating room with a special emphasis to the critical operating area. Together with the normal, daily cleaning of operating rooms, blue light disinfection makes it easier to keep the operating room surfaces clean and safe.
Benefits:
Laboratory tests on the effectiveness of the blue light disinfection system have been carried out in an accredited laboratory. The results show that the blue light photon disinfection produces relevant bacteria reductions. When combined with photocatalytic coating, relevant reductions are achieved already before 30 minutes.

Blue light disinfection units also include integrated white light LED elements, which enables high-quality general room lighting. This also leads to additional savings in lighting installation and leaves ceiling space free for other installations.

The diffuser is connected to the duct by screwing or by riveting. The duct connection spigot is equipped with a seal gasket. The diffuser can be installed in the following ways:
Note: When installing the unit, be careful not to drill any holes into the casing. If the casing is damaged, unfiltered air may leak.
The internal cabling of disinfection units is done at the factory. The external cabling is connected to the junction box at the site.
The unit should be cleaned on the inside before filter installation.
Filter integrity testing should be performed after filter installation.
The nozzles are preset to four directions at the factory.
If needed, the nozzles can be manually adjusted on site to create the desired airflow pattern. The nozzles can be adjusted in 15-degree intervals.
The required maintenance tasks include changing the filter and cleaning the supply air unit.
To ensure that the air quality meets the requirements, the HEPA filter must be checked frequently and, if needed, the filter must be replaced. The maintenance frequency of a filter depends on the air cleanliness of the supply air and room air.
The filter must be immediately replaced in the following cases:
The unit can be cleaned using disinfectants. The front panel can be removed and cleaned in a washing machine (water temperature < 95°C). The lockable nozzles ensure that the setting of the nozzles remains unchanged during cleaning.
Be careful not to wet the filters. Dampening the filter media will permanently decrease the filter efficiency.
For cleaning frequency, follow the maintenance schedule of the building.
Fig.19. HEPA filters
High efficiency particulate air (HEPA) filters are widely applied in cleanrooms where high air quality standards are
essential.
Note: Filters need to be ordered separately.
Filters compatible with the Halton Vita VHR HEPA diffuser are available in classes E10, H13 and H14 (European Standard EN 1822-1:2009) for standard and high airflow. The available filter depths are 68, 90 mm. All filters have a polyurethane (PUR) foam gasket.
