Introduction de produit

The U-shaped air shower uses two internal turns to connect both controlled openings to the same face of the enclosure. Directional nozzle zones follow the folded route, while returns at the bends collect dust close to where it is dislodged. This configuration supports facility retrofits where neither a straight nor an L-shaped transfer path can connect the gowning and clean areas.

Key Features

The folded passage puts entry and exit on one external face.

Successive cleaning zones lengthen exposure without requiring a stationary batch cycle.

Ceiling nozzles can cover garments as operators change orientation at the turns.

Returns at both bends reduce particle accumulation in internal corners.

Zoned fan sections support more even pressure across the two legs.

Préoccupations du client produit

A folded route must avoid stagnant corners and prevent the remote cleaning leg from becoming a low-pressure zone.

The two connected rooms are located on the same wall with no straight route.A U-shaped enclosure returns traffic after two controlled turns.

Lint builds up in inner corners when returns are only at the entrance.Dedicated return grilles at both bends collect contamination locally.

Remote nozzle rows lose pressure through a long common plenum.Zoned blower-filter sections supply each leg through shorter duct paths.

Users may be uncertain of the direction through a folded chamber.Sequential indicators can identify entry, cleaning route and clean-side exit.
