Ultra clean workbench high-efficiency filtercome fromAir ShowerThe manufacturer's ultra clean workbench high-efficiency filter draws air into the pre filter through a fan, enters the high-efficiency filter through a static pressure box for filtration, and sends the filtered air out in a vertical or horizontal airflow state, achieving a cleanliness level of 100 in the operating area and ensuring the environmental cleanliness requirements of production.

Introduction to high-efficiency filter manufacturers for ultra clean workbenches: Ultra clean workbenches, also known as clean workbenches, are designed to meet the cleanliness requirements of local work areas in modern industries, optoelectronics, biopharmaceuticals, and scientific research experiments. It draws air into the pre primary filter through a fan andHigh efficiency filterThrough the static pressure box, it enters the high-efficiency filter for filtration, and the filtered air is sent out in a vertical or horizontal airflow state to achieve a hundred level cleanliness in the operating area, ensuring the environmental cleanliness requirements of production.
The installation of high-efficiency filters on ultra clean workbenches is mostly of level 100, mainly divided into two categories: horizontal laminar flow and vertical laminar flow. According to the operation structure, it can be divided into two forms: unilateral operation and bilateral operation. According to its purpose, it can be further divided into ordinary ultra clean workbench and biological ultra clean workbench.
Attention: The ultra clean workbench is different from the biosafety cabinet. The ultra clean workbench can only protect the reagents and other substances operated inside the workbench from contamination, and does not protect the workers. However, the biosafety cabinet is a negative pressure system that can effectively protect the workers.

The ultra clean workbench consists of several parts, including metal inner and outer boxes made of steel plates and stainless steel, purification fans, medium and low efficiency filters, filters, static pressure chambers, control appliances, lighting ultraviolet lamps, universal moving wheels, and fixed wheels. We have learned about the components of the ultra clean table, and now let's understand its working principle. It sucks in air from the outside, passes through a medium to low efficiency simple filter, and reaches a filtration efficiency of about G45. Then, it is pressurized by a fan and a static pressure chamber, and passes through a filter to achieve an efficiency of 99.99% @ 0.5 microns of dust. The dust is evenly blown into the working area through the diffuser plate below the filter, and then discharged downwards or outward through the desktop, thus maintaining positive pressure from the operating area and achieving a hundred level purification.

There is no doubt that the high-efficiency filter of the ultra clean workbench has an external air inlet and is directly in contact with the outside world. Its dirty air and impurities are easily adsorbed onto the filter. We should clean and wash the medium efficiency of the external primary filter. Usually, the primary filter is made of non-woven cotton material and can be cleaned about 4-5 times before it must be replaced. After the initial filter, it mainly blocks dust of about 0.3-0.5 microns, with fine impurities that are directly adsorbed onto the filter paper. Due to the filter material being fiberglass paper, it cannot be cleaned and can only be replaced. The frequency of replacement generally depends on the external environment, usually every 2-3 years. Generally, pharmaceutical factories and operating rooms must replace it once a year.

So many customers may ask about the high-efficiency filter of our ultra clean workbench. How do we determine if our ultra clean workbench needs to replace the filter? Is there any instrument that can detect it? The editor will explain it to you. The initial filter is usually based on experience and judgment. If the initial filter turns black, it means that dirty air has blocked the initial filter.
There are several ways to judge this:
1. The equipment itself is equipped with a differential pressure gauge, which is usually mentioned to the manufacturer at the time of ordering. Guangzhou Zijing can provide a matching differential pressure gauge according to customer requirements;
2. Using a dust particle counter, this instrument can periodically inspect the interior of the ultra clean table. If its testing parameters exceed the standard allowable number of dust, the filter needs to be replaced. Due to the high price of dust particle counters and their infrequent use by customers, they are generally equipped with relatively few.
3. Using the empirical observation method, feel the size of the wind. If the wind speed is significantly lower than before, you can adjust it. If the wind speed is still too low after using for a period of time, you can only replace the high-efficiency filter and initial filter of the ultra clean workbench.Installation steps of high-efficiency air filter for ultra clean workbench:
Turn off the main power of the ultra clean workbench and let it not run or work. Use tools to disassemble the high-efficiency filter current protection plate, remove the original high-efficiency filter fixing pressure piece, remove the old high-efficiency filter, clean the surrounding frame of the filter with a dust-free cloth, reopen the ultra clean workbench for five minutes, blow open the new high-efficiency filter packaging, install the high-efficiency filter according to the installation instructions, restart the ultra clean workbench, use a particle counter to check for leaks in the high-efficiency filter, confirm the seal, reinstall the original workbench current plate, reopen the ultra clean workbench for cleanliness testing, and complete it after passing the inspection.

High efficiency filters are mainly used to capture particles, dust, and various suspended solids of 0.3um and below, with a filtration efficiency of 99.99% @ 0.3um. They use ultra-fine glass fiber paper as the filter material, adhesive paper, aluminum film and other materials as the dividing plate, and are bonded with aluminum alloy.

The high-efficiency filter of the ultra clean workbench draws air into the pre filter through a fan, enters the high-efficiency filter through a static pressure box for filtration, and sends the filtered air out in a vertical or horizontal airflow state, achieving a cleanliness level of 100 in the operating area and ensuring the environmental cleanliness requirements of production.What should be noted when replacing the high-efficiency filter of the ultra clean workbench
1. When replacing the high-efficiency filter of the ultra clean workbench, the machine should be stopped and the workbench should be sterilized first.

2. When replacing the high-efficiency filter of the ultra clean workbench, special attention should be paid to unpacking, handling, and installation to protect the filter paper from damage. It is forbidden to touch the filter paper with hands to cause damage.
3. Before installing the high-efficiency filter on the ultra clean workbench, place the new high-efficiency filter against the bright spot and visually inspect whether there are any leaks in the high-efficiency filter due to transportation and handling reasons. If there are vulnerabilities, they cannot be used.

4. When installing the high-efficiency filter on the ultra clean workbench, attention should also be paid to keeping the arrow mark on the high-efficiency filter consistent with the direction of the workbench's air outlet.
5. When tightening and clamping the gong nails of the high-efficiency filter on the ultra clean workbench, the force should be even, ensuring that the high-efficiency filter is fixed and sealed stably and reliably, and avoiding deformation of the high-efficiency filter that may cause leakage.

6. After replacing the high-efficiency filter of the ultra clean workbench, a dust particle counter should be used for leak detection, especially scanning and inspecting around the frame of the high-efficiency filter.

Ultra clean workbenches are divided into vertical flow ultra clean workbenches and horizontal flow ultra clean workbenches according to the direction of airflow. Ultra clean workbenches are divided into single-sided operation and double-sided operation according to their operating structure, and can be further divided into ordinary ultra clean workbenches and biological (pharmaceutical) ultra clean workbenches according to their purposes.
To ensure the cleanliness of the ultra clean workbench, we need to replace the high-efficiency air filter when it reaches the final resistance. Now, we will introduce the method of replacing the high-efficiency air filter of the ultra clean workbench.
