An air shower is a self-contained unit used in cleanrooms and controlled environments to minimize particulate contamination. Personnel and materials pass through the air shower before entering the cleanroom to ensure that contaminants such as dust, lint, and other particles are removed from clothing and equipment surfaces.
Decontamination:Air showers use high-velocity, HEPA-filtered air jets to dislodge and remove contaminants from personnel and materials.
– Airflow: The air is recirculated within the shower to maintain efficiency and cleanliness.
– Design: Air showers typically have interlocking doors to ensure that one door is always closed, preventing contamination from entering or exiting the cleanroom.
Features:
– Automatic Operation: Sensors detect the presence of personnel or materials and activate the air shower cycle automatically.
– Interlocking Doors: Prevent cross-contamination by ensuring one door is closed before the other can be opened.
– High-Velocity Air Jets: Positioned strategically to cover the entire body and surfaces uniformly.
– HEPA Filters: Ensure that the air used in the decontamination process is free from contaminants.
Applications:
– Pharmaceuticals
– Biotechnology
– Electronics manufacturing
– Aerospace
A pass box (also known as a transfer hatch) is a device used to transfer materials between cleanrooms or between a cleanroom and the outside environment without compromising the cleanliness of the controlled environment.
Function
Transfer of Materials: Allows the safe transfer of materials while maintaining the integrity of the cleanroom.
Decontamination: Some pass boxes are equipped with UV lights or HEPA filters for decontaminating materials.
Types:
– Static Pass Box: Used for material transfer without an air circulation system.
– Dynamic Pass Box: Equipped with HEPA filters and airflow systems to ensure materials are decontaminated during the transfer process.
Features:
– Interlocking Doors: Prevents both doors from being opened simultaneously, maintaining pressure differentials and preventing contamination.
– Stainless Steel Construction: Ensures durability and ease of cleaning.
– UV Germicidal Lamps: Optional feature for additional decontamination of materials.
Applications:
– Pharmaceutical manufacturing
– Laboratories
– Semiconductor industry
– Hospitals
Overview:
A garment cabinet is a storage unit used in cleanrooms to store cleanroom garments such as suits, gloves, masks, and boots. It ensures that these items remain free from contamination when not in use.
Function:
– Storage: Provides a clean environment for storing garments to prevent contamination.
– Decontamination: Some cabinets are equipped with HEPA filters or UV lights to maintain the cleanliness of stored items.
Features:
– HEPA Filtration: Ensures the internal environment of the cabinet remains contaminant-free.
– Stainless Steel Construction: Durable and easy to clean, ideal for maintaining hygiene.
– Air Circulation System: Maintains a flow of clean, filtered air within the cabinet to prevent the buildup of contaminants.
– UV Lighting: Optional feature for additional sterilization.
Applications:
– Cleanroom environments
– Laboratories
– Pharmaceutical manufacturing
– Electronics manufacturing
Benefits of Using Air Showers, Pass Boxes, and Garment Cabinets:
– Enhanced Cleanliness: Reduces the risk of contamination in cleanrooms.
– Operational Efficiency: Facilitates the smooth transfer of materials and personnel while maintaining a controlled environment.
– Compliance: Helps in adhering to stringent industry standards and regulations for cleanliness and hygiene.
– Product Quality: Ensures high product quality by minimizing particulate contamination.
