Clean rooms are controlled environments with low levels of airborne particles and contaminants. The equipment contained in a clean room can vary depending on the specific needs and requirements of the facility. Here are some common types of clean room equipment:

1. HVAC (Heating, Ventilation, and Air Conditioning) Systems: Clean rooms rely on HVAC systems to control temperature, humidity, and air filtration. The HVAC system ensures a continuous supply of filtered and conditioned air to maintain the desired cleanliness level within the room.

2. Air Filters: High-efficiency particulate air (HEPA) filters or ultra-low particulate air (ULPA) filters are used to remove particles and contaminants from the air. These filters are installed in the air handling units and clean room air supply outlets to maintain a clean and particle-free environment.

3. Clean Benches and Workstations: Clean benches are enclosed workstations equipped with HEPA-filtered air supply. They provide a localized clean and sterile environment for carrying out specific tasks, such as handling sensitive materials or conducting experiments.

4. Air Showers: Air showers are chambers equipped with high-velocity air jets that blow off particles from personnel or equipment before they enter the clean room. They help reduce contamination by removing loose particles from surfaces and clothing.

5. Pass-Through Chambers: Pass-through chambers are used to transfer materials and equipment between the clean room and the adjacent areas without cross-contamination. They have interlocking doors that allow one door to open at a time to maintain the separation of clean and non-clean areas.

6. Laminar Flow Cabinets: Laminar flow cabinets create a unidirectional airflow over the work area, providing a sterile environment for handling sensitive equipment or conducting procedures that require a high level of cleanliness.

7. Clean Room Furniture: Clean rooms may include specialized furniture such as stainless steel workbenches, storage cabinets, material transfer carts, and chairs designed to minimize particle generation and facilitate easy cleaning.

8. Monitoring and Control Systems: Clean rooms are equipped with monitoring and control systems to maintain and monitor environmental parameters such as temperature, humidity, air pressure differentials, particle counts, and airflow velocity. These systems ensure that the clean room conditions are within the specified ranges.

9. ESD (Electrostatic Discharge) Control Equipment: Depending on the requirements of the clean room, electrostatic discharge control equipment such as grounded flooring, antistatic garments, wrist straps, and footwear may be used to prevent damage to sensitive electronic components.

It's important to note that the specific equipment in a clean room can vary based on the industry, clean room classification, and the specific processes being performed within the clean room environment.
