Structure and materials

Function

Air is filtered inside the modules by HEPA filters and supplied into space through the air nozzles located in the front panel of the unit.

The circumferential supply airflow from the supply air unit is directed partly towards the operating area and partly towards the room periphery. The inward supply airflow displaces the contamination generated in the operating area and prevents the intrusion of the outward supply airflow into the centre. The fine-tuning of the throw pattern is carried out by Halton.

The supply unit size and airflow pattern adjustment are optimised by Halton based on the end-user requirements and specifications.

Filters

Description

High-efficiency particulate air (HEPA) filters are widely applied in cleanrooms where high air quality standards are essential.

Performance data of HEPA filters

Filter compatible with Halton VSN is available in class H14 (European Standard EN 1822-1:2009) with gel gasket.

Operating range:

• Temperature max. 70 °C
• Humidity max. 90 %
• Final pressure drop max. 500 Pa

Number of filters

Installation

The Halton Vita OR Space supply air units are installed onto the operating room ceiling before the installation of the false ceiling.

Hang the modules from the ceiling with M8 drop rods using fixing brackets. Bolt the modules together with M6 bolts.

CAUTION!

Do not drill any holes into the casing. If the casing has been damaged, unfiltered air may leak.

Clean the modules on the inside before the filter installation.

Filter integrity testing should be performed after filter installation.

NOTE: Step-by-step instructions on how to install Halton Vita VSN can be found in the Halton Vita VSN Installation Guide. Contact Halton sales to get the installation guide.

Adjustment

The airflow rate for each duct connection of the Halton Vita OR Space solutions should be balanced so that an equal amount of air is supplied via each connection. As a result, the airflow is distributed evenly throughout the supply air modules and no additional airflow adjustment is needed.

Adjustment of the supply airflow pattern is done by turning the nozzles.

Servicing

The required servicing tasks include filter change and cleaning the unit.

To ensure that air quality meets the requirements check the HEPA filter in short time intervals and replace the filter when necessary. The servicing frequency of a filter depends on the air cleanliness of the supply air and room air. Replace the filter immediately if:

• the final differential pressure has been reached
• the filter is damaged
• micro-organisms, fungal spores, or odours are present in the space

Clean the unit with disinfectants.

CAUTION!

Do not wet the filters. Dampening the filter media will permanently decrease the filter efficiency.

The front panel can be detached and cleaned in the pre autoclave washing machine (<95°C). Lockable nozzles, that ensure that nozzles setting is not changed during cleaning.
