Customized Size Stainless Steel 304 Air Shower for Food Industry in Portable Cleanroom

Product Overview

Air Shower

Air showers are enclosed chambers installed at the entrances to cleanrooms and other controlled environments. They serve to minimize the ingress or egress of airborne particulate contamination. Personnel and materials passing through are subjected to a thorough cleaning cycle via high-velocity jets of HEPA-filtered air, typically at speeds of 20-22 m/s (4000-4300 fpm). Following this cycle, the contaminated air is drawn through floor grilles, filtered, and recirculated within the system.

How the Air Shower Works

The personnel purification route includes an air shower installed between the gowning area and the controlled cleanroom area.

• 1. Personnel Entry
  Personnel walk into the air shower from the gowning or lower-cleanliness side.
• 2. Door Interlocking
  The entrance and exit doors are handled by an interlocking system to help keep both doors from opening at the same time during normal operation.
• 3. Air Shower Cycle
  Supplied through directional nozzles, filtered air removes loose particles from exposed surfaces of cleanroom garments.
• 4. Air Recirculation and Filtration
  The air circulation system recovers air and drives it through the filtration system according to the equipment configuration.
• 5. Cleanroom Entry
  After the programmed shower cycle finishes, 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 selected with reference to the cleanroom design and project requirements.

Features at a Glance

1. Effective Personnel & Material Decontamination

• • High-Efficiency Particle Removal: Utilizes high-velocity (typically 20-25 m/s), uniform HEPA-filtered airflow to effectively dislodge and remove most particulate contaminants (e.g., dust, fibers, skin cells) from personnel garments, exposed skin, and material surfaces.

  • Comprehensive Coverage: A strategically designed nozzle array ensures full-body coverage, including often-missed areas like the back, underarms, and footwear.

2. Superior Contamination Control & Isolation

• • Physical Air Barrier: Acts as an "airlock" at the cleanroom entrance, preventing direct air exchange between contaminated external air and the clean internal environment, thereby helping to maintain cleanroom positive pressure.

  • Cross-Contamination Prevention: Significantly minimizes the risk of contaminants being carried from lower-classification areas into higher-grade clean zones when placed between them.

3. Process Standardization & Personnel Discipline

• • Mandatory Decontamination Cycle: Enforces a standardized cleaning procedure for all entrants through a preset, timed cycle (e.g., 15-30 seconds), eliminating variability due to individual behavior.

  • Enhanced Cleanroom Awareness: The process itself serves as a physical reminder, reinforcing proper gowning and cleanroom protocol discipline among personnel.

Testing & Validation

• Visual checking of the unit
• Dimensional conformity inspection
• Door movement and operation test
• Door interlocking check
• Fan operational verification
• Lighting functional verification
• Control panel operations check
• Airflow checking and verification
• HEPA integrity testing where necessary

Manufacturing Capability

Established in 2003 in Suzhou, China, SHP is a cleanroom engineering and manufacturing enterprise.

With over two decades of cleanroom engineering experience and a workshop exceeding 10,000 m², SHP manufactures and integrates cleanroom equipment such as Air Shower Rooms, FFUs, Pass Boxes, HEPA Boxes, Clean Benches, Cleanroom Doors and HVAC systems.

Air Shower production involves enclosure fabrication, fan and filtration assembly, door and interlock installation, electrical control integration, and pre-shipment inspection following the approved project configuration.

4. Operational Economy & Sustainability

• • Air Recirculation: Over 95% of the air is recirculated within the unit after HEPA filtration, drastically reducing the load on the main HVAC system and fresh air makeup requirements, leading to significant energy savings.

  • Reduced Long-Term Costs: By intercepting the bulk of contaminants at the entry point, air showers extend the service life and reduce the maintenance frequency/cost of the cleanroom's primary filtration system.

5. Versatile Application & Adaptability

• • Flexible Configurations: Available in single-person, double-person, multi-person, or material/tunnel versions. Can be customized with various materials (e.g., stainless steel, powder-coated steel) for standard, ESD-safe, or corrosive environments.

  • Smart Integration: Can be equipped with access control systems, electronic interlocking doors, motion sensors, voice prompts, and touch-screen controls for automated, intelligent operation.

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.
