Product Overview
The Multi-Person Air Shower Room is a high-capacity contamination control solution designed for simultaneous use by 2 to 6 personnel or for cleaning small cargo passing into cleanrooms. It provides a high-velocity, HEPA-filtered air stream that removes particulate contamination from work garments and material surfaces before entering controlled environments (ISO 5 to ISO 8 / Grade A to C).
This unit is ideal for facilities requiring high personnel traffic without compromising cleanroom integrity.
Key Features
-
Multi-User Access
Accommodates 2–6 persons per cycle, significantly reducing entry waiting times in high-traffic cleanrooms. -
High-Efficiency Filtration
Equipped with HEPA or ULPA filters (≥99.99% efficiency at 0.3 µm or 0.1 µm) to guarantee particle-free air jets. -
Interlocked Entry & Exit Doors
Heavy-duty magnetic or electronic interlocks prevent both doors from opening simultaneously, ensuring unidirectional airflow and maintaining room pressure. -
Optimized Nozzle Configuration
Strategically positioned stainless steel or ABS air nozzles on both side walls and ceiling provide complete body coverage (top-to-bottom air sweeping). -
PLC Control System with HMI
User-friendly touchscreen or keypad interface with adjustable cycle time (10–99 seconds), emergency stop, automatic cycle start, and cycle completion alarm. -
Industrial-Grade Construction
Manufactured from cold-rolled steel (CRS) with electrostatic powder coating or 304 stainless steel for durability and cleanroom compatibility. -
Energy-Saving Operation
Low-noise blower with automatic standby mode and timer-controlled shutdown reduces power consumption between cycles.

1
How often should air shower filters be maintained?
Check air velocity regularly using anemometer (must remain ≥20 m/s). Replace pre-filters and HEPA filters based on differential pressure gauge readings or scheduled maintenance plan. Clean interior walls monthly with lint-free cloth
2
Can multiple people use an air shower simultaneously?
Strictly adhere to maximum occupancy (usually 1-2 people). Crowding disrupts indoor airflow and leads to incomplete purification. Allow intervals between groups for self-purification
3
What personal preparation is required before entering?
Change into dedicated lint-free cleanroom clothing, ensure hair is completely covered by cap, remove all jewelry, avoid makeup and perfume that shed particles. Street clothes are significant contamination sources.
4
Why is rotating during the shower cycle important?
Standing still creates purification "dead spots" where airflow cannot reach areas like back, underarms, and knees. Active rotation (at least one full turn) with arm movements ensures complete surface exposure.
5
What happens if both doors are opened simultaneously?
Opening both doors bypasses the airlock function, allowing unfiltered non-clean air to flow directly into the clean area, completely destroying pressure differential and compromising cleanliness classification
6
What is the proper procedure for using an air shower?
Enter, close outer door completely, stand in center, slowly rotate 360 degrees with arms raised for thorough coverage, wait for preset time (15-30 seconds), then open inner door and enter clean area
7
Where should air showers be installed in a cleanroom?
Install between changing rooms and clean areas, or between ISO 8/ISO 7 classified areas and unclean areas. Personnel pass through after changing into cleanroom clothing but before entering the controlled environment.
