Doccia d'aria

L’unità doccia d’aria è una macchina depolverante utilizzata per soffiare le superfici di indumenti indossati od oggetti trasportati in ingresso ad un’area a contaminazione controllata. La depolverazione avviene per mezzo dell’azione di getti d’aria filtrati attraverso un setto ad alta efficienza e soffiati a forte velocità ( > di 20m/s ) all’interno della camera di passaggio. Tale azione provoca il distacco del particellare investito in più direzioni da parte del flusso d’aria il quale viene infine trasportato verso il basso e ricircolato per mezzo di griglie di ripresa, essendo la camera interna del depolveratore mantenuta in leggera depressione nei confronti dell’ambiente esterno.    

The air is pulled downwards and re-circulated via G3 pre-filter grids by virtue of the slight negative pressure kept inside the transfer chamber in comparison to the surrounding environment. The air is channeled through G3 pre-filters and high efficiency H14 HEPA/ULPA filter and blown into the chamber. The resulting clean air inside the unit is in Class ISO 5 quality according to ISO 14644-1 Standard.

Full body of the Air Shower manufactured in AISI 304L stainless steel with Scotch Brite pharmaceutical-grade finishing.

Doors are manufactured in stratified safety glass of 8 mm thickness flush mounted within the body of the unit (without any unsightly aluminum frames), installed one in front of the other or square mounted; interlocked electromagnetic automatic release system allows the opening at the end of each dust removal cycle.

Handle bars made in stainless steel.

Ventilation is provided by double inlet centrifugal electrical fan with nominal air flow rate of 2.400 m3/h - at an operational pressure of 1.600 Pa.

Filtration: 1st bank – Class H14 high pressure drop HEPA/ULPA filter according to CEN EN 1822, 2nd bank – Class G3 coarse particulate prefiltration.
Access for filters replacement is from the inspection panel mounted on top of the unit. Pre-filter panels are fitted with quick-release system (no screws needed for removal of the panel).

Pressure control is provided by means of analogic Dwyer manometer to check the differential pressure on the filter face.

Air nozzle: The air is blown into the transfer chamber by means of adjustable air-nozzles made in aluminum with internal damper to regulate the air flow outlet. Air flow speed is manually adjustable within a range between 20 to 30 m/s.

Half speed: Air flow speed reduction starts automatically at the end of each cycle.
