Clean Work Room Air Shower with GMP Standard and Electronic Interlock Air Filtration

Product Overview

How the Air Shower Works

An air shower is placed between the gowning area and the controlled cleanroom area as part of the personnel purification route.

• 1. Personnel Entry
  From the gowning or lower-cleanliness side, personnel enter the air shower.
• 2. Door Interlocking
  The entrance and exit doors are operated under an interlocking system designed to help prevent both doors from opening at the same time during normal operation.
• 3. Air Shower Cycle
  Filtered air is provided via directional nozzles to remove loose particles from exposed surfaces of cleanroom garments.
• 4. Air Recirculation and Filtration
  The air circulation system, recovering air, passes it through the filtration system according to the equipment configuration.
• 5. Cleanroom Entry
  After the programmed shower cycle is finished, the exit door can be released and personnel proceed into the controlled area.

The actual shower cycle, airflow configuration, filtration arrangement and control logic should be determined according to the cleanroom design and project requirements.

Features at a Glance

• Core Purification Function:Forced Surface De-dusting
  • Uses high‑velocity clean airflow (20‑28 m/s) to conduct all‑around blowing on personnel/material surfaces, physically dislodging and removing adhering particles (typically ≥0.5 µm). It is the mandatory final step of surface purification before entering the clean area.
• Airlock Barrier Function:Prevention of Cross‑Contamination
  • Employs a "dual‑door interlock" design to ensure the inner and outer doors cannot be opened simultaneously, creating a physical airlock that effectively prevents direct airflow exchange between untreated external air and cleanroom air, maintaining the integrity of the clean zone’s airflow and pressure.
• Pressure Differential Maintenance:Stabilizing the Clean Environment
  • Acts as a dynamic airlock chamber that helps establish and maintain a positive pressure differential between the clean area and the external corridor or non‑clean area at the entry point, preventing contaminated air from back‑flowing due to pressure differences.
• Contamination Control Function:Reduction of Human‑Borne Contamination
  • Serves as a key component of the cleanroom "contamination control strategy," significantly lowering the risk of particles, fibers, and other contaminants generated and carried by human activity (movement, friction) from entering the core controlled environment.
• Air Recirculation Function:Energy Saving & Continuous Purification
  • Utilizes a recirculating filtration system: "Dirty air" after showering is collected through bottom return vents, filtered again through pre‑filters and HEPA filters, and then recirculated as clean air for showering, enabling efficient air reuse and operational energy savings.
• Management & Alert Function:Process Standardization & Behavioral Guidance
  • - Mandatory Procedure: Interlock logic enforces completion of the full shower cycle.
    - Audio‑Visual Indicators: Signal lights and buzzers indicate shower status (ready, in progress, completed), standardizing user behavior.
    - Adjustable Timing: Shower duration (typically 15‑30 seconds) can be set according to cleanliness class requirements.

Cleanroom Applications

Air shower rooms are integrated into the personnel purification route between gowning areas and controlled cleanroom spaces as standard.

Representative applications include:

• Pharmaceutical manufacturing plants
• Healthcare and medical establishments
• Laboratory installations
• Semiconductor and electronics factories
• Food and beverage industries
• Cosmetics and beauty product manufacturing
• Precision engineering facilities

The cleanroom layout, personnel flow, cleanliness requirements and operating procedures should guide the selection of the air shower configuration, which should not be treated as an isolated equipment component.

Engineering & Customization Process

• 1. Requirement Analysis
  Analyse the cleanroom classification, personnel flow, available installation space and operating requirements.
• 2. Configuration Design
  Select the type, dimensions, door arrangement, filtration and control configuration of the air shower according to the project.
• 3. Manufacturing
  Fabricate and assemble the chamber, filtration, fan section, doors and control components according to the approved configuration.
• 4. Factory Inspection
  Verify the assembled unit, electrical system, door operation, interlock function and other applicable items before shipment.
• 5. Installation & Commissioning
  According to project requirements, support site installation, connection and functional commissioning.
• 6. Documentation
  Provide applicable product drawings, operation manuals, maintenance information and testing records.

Testing & Validation

• Visual scrutiny
• Verification of dimensions
• Door performance test
• Interlock functioning test
• Fan run test
• Light operation test
• Control panel operational check
• Checking of airflow
• Where applicable, HEPA integrity testing

Products Description

• Slide rail style door closer:A slide rail door closer for air showers is a high-durability, high-precision core functional component designed to safeguard cleanroom environments.
• LCD control screen:The LCD control panel is not only the "intelligent brain" of the air shower but also a critical component that enhances equipment reliability, operational efficiency, and management standards.
• Stainless steel nozzle:For cleanrooms with high standards, high-frequency usage, and stringent certification requirements (such as those in , biotechnology, microelectronics, precision instruments, etc.), stainless steel nozzles are an essential and wise choice. They offer exceptionally long service life, nearly zero maintenance costs, and irreplaceable reliability.
  
• High efficiency filter:The HEPA filter is the "lungs" of the air shower, directly determining the quality of the blown air. Its ultra-high filtration efficiency, stable performance, and compliance are non-negotiable advantages.
