Air Showers Services for Industrial Projects
Basic Description
Sagiant Piping Industries manufactures air showers for cleanroom entry — stainless steel 304/316 cabins with high-velocity HEPA-filtered air jets that remove particulate from personnel and goods before entry. Air showers use H14 HEPA filters, a centrifugal blower and adjustable nozzles delivering 20–25 m/s jet velocity, with interlocking doors, microprocessor timer control and single-person, multi-person or pass-through tunnel configurations built to ISO 14644 and EU/cGMP practice.

Frequently Asked Questions
How does an air shower work?
HEPA-filtered air is blown through adjustable nozzles at 20–25 m/s to dislodge and remove particulate from personnel or goods before they enter the cleanroom; interlocked doors enforce the cycle.
What HEPA grade is fitted?
H14 HEPA filters (99.995% at MPPS per EN 1822) with a washable pre-filter.
What configurations are available?
Single-person, multi-person, pass-through tunnel and wide-door cargo/goods air showers.
What material is used?
Fully welded stainless steel 304 or 316 cabins with coved corners and a No.4 passivated finish.
Are the doors interlocked?
Yes — electromagnetic interlocks with a microprocessor timer ensure the shower cycle completes before the inner door releases.
Scope of Work
The air showers scope can include project review, fabrication support, dimensional coordination, inspection documentation and dispatch support for industrial installations.
