• Frame Material

  The frame of the clean room is usually made of industrial aluminum profiles or stainless steel squares, which are not only strong and beautiful, but more importantly, they do not rust or produce dust, and are able to withstand a variety of harsh working environments. Aluminum profiles are widely used in the construction of clean rooms because of their light weight, high strength and corrosion resistance. Stainless steel squares, on the other hand, are one of the preferred materials for constructing the framework of clean rooms because of their excellent load-bearing capacity and durability.

• Wall Material

  The walls of clean rooms are usually made of anti-static curtains, acrylic panels or tempered glass. Anti-static curtains prevent the generation of static electricity and damage to sensitive electronics. Acrylic panels and tempered glass are often used as viewing windows or doors in cleanrooms due to their high light transmission and ease of cleaning. The common goal of these materials is to provide an environment that prevents dust intrusion and ensures adequate light penetration.

• FFU System

  FFU (Fan Filter Unit) is an important part of the clean room, it is responsible for providing a continuous flow of clean air to ensure the cleanliness of the room, FFU usually adopts low noise centrifugal fan, with a long life, low noise, maintenance-free, small vibration, adjustable speed, etc., the quality of the fan is reliable, and the working life is long.

• Lighting system

  The lighting system inside the clean room needs to use non-dust-producing materials, such as LED lamps, to ensure sufficient illumination and uniform light distribution, while avoiding the generation of new pollutants.

Industrial Clean Room

Industrial clean room is mainly to control the air dust micro-substances on the contamination of the work object, the internal generally maintain a positive pressure state, in order to prevent the intrusion of external pollutants. This type of clean room is suitable for precision machinery industry, electronics industry (such as semiconductors, integrated circuits, etc.), aerospace industry, high-purity chemical industry, atomic energy industry, optical and magnetic products industry (such as CD-ROM, film, tape production), LCD (liquid crystal glass), computer hard disk, computer magnetic head production and other industries.

Biological Clean Room

There are two types of biological cleanrooms: general biological cleanrooms and biosafety cleanrooms. The former mainly controls the contamination of microorganisms (bacteria) on the work object, the internal materials need to be able to withstand the erosion of various biocides and maintain a positive pressure; the latter mainly controls the contamination of the work object's live micro-substances on the outside world and human pollution, the internal and the atmosphere should be kept at a negative pressure in order to prevent contamination from spreading.

Unidirectional flow (laminar flow) clean room

Unidirectional flow clean shed, also known as vertical flow or parallel flow clean shed, which is characterized by a uniform cross-section of air velocity along the parallel flow line one-way through the entire room ceiling cross-section, through the clean room. In order to achieve the ideal “plug flow” effect, the most critical thing is to ensure that the filter is full. China's “Clean Plant Design Code” stipulates that the full coverage rate of a vertical flow cleanroom should not be less than 60%, and the full coverage rate of a horizontal unidirectional flow cleanroom should not be less than 40%.

Structural features

• Assembled structure design: easy to install and short delivery cycle.

• Easy to move: can be realized by installing universal wheels.

• Modularized design: easy to improve the cleanliness level, strong expandability, and high reuse value.

• Internal purification level: up to 100-100K level, especially suitable for the area with high local purification level requirement in the workshop, such as assembly line operation area.

Application areas

• Electronic factory: used in assembly line operation area, inspection table, etc.

• Food factory: to meet the GMP standard and improve the food safety compliance rate.

• Laboratory: to provide the necessary environment for scientific research projects.

• Healthcare: such as operating rooms, ICU wards, etc.

• Biopharmaceuticals: Ensure sterile conditions for drug production.

• Preparation before installation

  Before installing the FFU on top of the clean shed, the clean shed must be thoroughly cleaned and wiped down to ensure that the inside of the purified air conditioning system is free of dust. If a high-efficiency filter is installed in the technical mezzanine or ceiling, the technical mezzanine or ceiling also needs to be thoroughly cleaned and wiped.

• Testing of FFU systems

  After the clean booth and FFU system have met the cleaning requirements, the FFU system must be tested. After 12 hours or more of continuous operation, the clean shed is cleaned again and the FFU matching high-efficiency filter is installed immediately.

• Transportation and storage of FFU high-efficiency filter

  The transportation and storage of FFU high-efficiency filters should be placed in the direction indicated by the manufacturer. During transportation, it should be held gently and placed lightly to avoid violent vibration and collision.

• Inspection before installation

  Before installing the FFU high-efficiency filter, the package must be unpacked and inspected at the installation site, including whether the filter paper, sealant and frame are damaged, whether the side length, diagonal and thickness dimensions are in accordance with the requirements, whether there are burrs and rust spots on the frame (if it is a metal frame), whether there is a certificate of conformity of the product, and whether the technical performance is in accordance with the design requirements. After that, check whether there is leakage, and install it immediately after passing inspection and leakage detection.

• Reasonable distribution of filter resistance

  The installation should be reasonably allocated according to the resistance of each filter. For unidirectional flow, between the filters of the same air outlet or air supply surface, the difference between the rated resistance of each filter and the average resistance of each filter should be less than 5%.

• Preparation before testing

  Prior to clean shed testing, the purified air conditioning system should be operated continuously for at least 24 hours to ensure stability of the environmental parameters. Such a warm-up period helps to stabilize the system and equalize the parameters.

• Temperature and humidity testing

  For constant temperature and humidity requirements, continuous measurements are taken for 8 to 48 hours with an interval of no more than 30 minutes between each measurement, as required by the temperature and humidity fluctuation range. This can accurately reflect the temperature and humidity changes of the environment in the clean room.

• Test Point Setting

  Test points should be set from the ground 1 to 1.5 meters, and should be staggered, the distance from the external wall should be more than 0.5 meters. Such a layout is conducive to obtaining more accurate test data.

• Number of test points

  According to the relevant norms, for a space with an area of less than or equal to 50 square meters, the number of measurement points should be 5, and for every increase of 20 to 50 square meters, the number of points should be increased by 3 to 5. Such a setup can better cover the space and ensure the representativeness of the test results.

• Testing Instruments

  Test instruments used include thermo-hygrometers or alcohol thermometers. These instruments need to be calibrated regularly to ensure the accuracy of the data.

• Qualification Criteria

  A clean room inspection is considered satisfactory when more than 90% of the test points achieve deviation values within the design parameters. This means that the vast majority of test points should meet the preset environmental criteria.
