DETAIL:
Overview
The Single-Person Air Shower Room is a compact contamination control device designed for entry points to cleanrooms and controlled environments. It directs high-velocity HEPA-filtered air through adjustable nozzles to remove dust, particles, and loose fibers from personnel and their garments prior to entering a clean area.
Key Features
-
Single-User Operation
Designed for one person per cycle, ideal for low-to-medium traffic cleanrooms (ISO 5 to ISO 8 / Grade A to C). -
High-Efficiency Filtration
Equipped with HEPA or ULPA filters (≥99.99% efficiency at 0.3 μm or 0.1 μm) to ensure particle-free jet streams. -
Interlocked Doors
Magnetic or electronic interlocks prevent both doors from opening simultaneously, maintaining cleanroom pressure and preventing cross-contamination. -
Adjustable Air Nozzles
Stainless steel or ABS nozzles positioned at various angles to ensure complete body coverage (top-to-bottom air sweeping). -
Programmable Logic Control (PLC)
User-friendly control panel with cycle duration (adjustable 10–99 seconds), emergency stop, and auto-start function. -
Durable Construction
Cold-rolled steel (CRS) with electrostatic powder coating or 304 stainless steel for cleanroom compatibility and corrosion resistance. -
Energy-Efficient Design
Low-noise blower and timer-controlled shutdown to reduce power consumption during idle periods.

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.
