Cleanroom cleanliness levels are generally categorized as: Class 1, Class 1, Class 1, Class 10,000, and Class 300,000. Class 10,000 cleanrooms are typically used in fields such as electronic instruments, computer rooms, semiconductor factories, color printing plants, automotive industry, aviation industry, photolithography technology, and micro-machine production and manufacturing.

The demand for a 100,000-class clean room goes beyond simply requiring an air cleanliness of 100,000-class; it must also ensure the elimination of static electricity. SAREN Sanren Purification has been primarily engaged in the design and construction of engineering projects such as air filtration for many years. The company has extensive experience and substantial design capabilities, construction abilities in various fields of purification, including clean industrial production environments, hospital infection control, animal experiment environments and equipment. It has provided superior products and engineering services for the construction of clean rooms for enterprises, earning excellent reputation and becoming a partner of customer satisfaction and trust. Today, I'll introduce the specific standards for a 100,000-class clean room.

Monte Environmental Clean Engineering Case

Particle

Dust particles are carriers of pathogens, so the top priority of the dust removal project in the 100,000-class clean room engineering project is "dust elimination."

In the 100,000-class clean room, the number of particles with a diameter larger than or equal to 0.5 millimeters should not exceed 3.5 million.

Particle count of 5mm or greater cannot exceed 20,000.

Section II: Microbial Strains

Microbial strains, like dust particles, also have a significant tolerance level. The specified limit for viable bacteria is no more than 500 per cubic meter.

2. The沉降bacterial count must not exceed 10 per cell culture dish.

Pressure differential

Here, there are two scenarios based on cleanroom classification:

Cleanrooms of the same grade must maintain consistent differential pressure.

2. Cleanrooms of different cleanliness levels must have an intermediate pressure difference of ≥5Pa between adjacent cleanrooms, and ≥10Pa between cleanrooms and non-cleanrooms (the primary purpose here is to ensure that gas flows from the clean area to the non-clean area, preventing backflow).

Section 4: Performance Parameters

The number of air changes, pressure difference, environmental temperature, air humidity, noise levels, and the supplementary amount of fresh air in a 100,000-class purification workshop are crucial during construction. Each has its standard value.

Air Changes: 10-15 times per hour

2. Differential Pressure: Main production workshop relative to adjacent rooms ≥ 5 Pa

3. Environmental Temperature: Winter > 16℃ ±2℃; Summer < 26℃ ±2℃

4. Relative Humidity: 45-65% (RH)

Noise level ≤ 65dB(A)

6. Supplemental Airflow for Air Purification System: Total supply and exhaust airflow ranging from 20% to 30%; luminous intensity of 300 Lux or higher.

V. Raw Material Regulations

Within the factory area, different materials must be used in various locations to ensure compliance with the ten-thousand-grade cleanroom standards.

 Walls and cast-in-situ slabs: Made with 50mm thick color steel sandwich panels and air purification treated aluminum alloy profiles.

2. Doors and Windows: Select purification-processed steel doors and aluminum alloy glass window sashes.

3. Flooring: Choose self-leveling epoxy floor paint or high-end wear-resistant plastic for clean wooden flooring.

4. Ventilation ducts with purification treatment: made of galvanized thin steel plate and insulated with "PEF" flame-retardant thermal insulation boards.

As industries across the board strive to meet customers' ever-higher demands, cleanrooms are becoming increasingly widespread. I hope my sharing will provide you with a deeper understanding of the standards for ten-thousand-level cleanrooms.
