Product Introduction

The stainless steel air shower uses SUS 304 for the visible chamber surfaces, doors, return grilles and nozzle faces. Its satin or hairline finish is wipeable and non-flaking, while radiused internal trims reduce crevices where moisture or debris can remain. Behind the hygienic liner, the recirculation system supplies filtered air through adjustable stainless nozzles.

Key Features

Exposed SUS 304 surfaces resist moisture better than ordinary painted mild steel.

Smooth sealed seams reduce dirt-retaining crevices in the occupied chamber.

Stainless nozzle faces and grilles tolerate frequent wipe-down.

A separated service plenum keeps filters and electrical parts outside the hygiene zone.

Compatible stainless hardware helps prevent staining on visible surfaces.

Customer Product Concerns

Wet sanitation and humid process conditions demand a shower enclosure that remains smooth, corrosion resistant and easy to inspect.

Painted panels chip or blister under repeated sanitation.SUS 304 exposed sheet provides a durable cleanable surface without a paint film.

Sharp seams retain moisture and cleaning residue.Flush joints and radiused trims reduce internal ledges.

Wipe-down water reaches service components.A partitioned service plenum separates controls, motors and filters from the chamber interior.

Mixed-metal fasteners leave stains on stainless panels.Compatible stainless hardware and controlled finishing minimise galvanic marks.
