Product Introduction

The multi-person air shower is assembled from scalable enclosure bays to create a wider cleaning area for groups. Each bay contributes filtered airflow and nozzle coverage, while zoned returns prevent contamination from travelling the full chamber length before collection. It can be arranged as a batch entry chamber for shift changes or as a short walk-through route when personnel flow requires it.

Key Features

Repeated fan-filter bays increase capacity with the length of the chamber.

Nozzle zones can cover both outer and central standing positions.

Segmented returns reduce long contaminated-air paths.

A robust modular frame supports wider group-access openings.

Bay-by-bay service access allows staged maintenance.

Customer Product Concerns

Group cleaning brings higher traffic and dust load, so air distribution and movement control are fundamental to the enclosure design.

Central occupants receive less direct cleaning air than those at the walls.Multiple sidewall zones and optional ceiling outlets extend coverage toward the centre.

Long common ductwork produces weak jets at the far end.Repeated pressure modules keep each nozzle zone close to its air source.

Crowded shift traffic interrupts the intended cleaning sequence.Wide access, occupancy indication and programmed interlocks organise each batch.

Large dust loads clog one small prefilter quickly.Zoned return paths distribute collection across several serviceable prefilters.

Typical Applications

Large pharmaceutical gowning roomsSemiconductor shift entrancesDisplay-panel productionAerospace controlled assembly
