1) Airflow velocity is reduced to the minimum. In this case, 2) resistance up to 2 times the initial resistance In this case, 3) there can not repair the leakage.

When the cleanliness is unqualified, the scanner can scan efficiently. The wind speed can also be tested by anemometer. If the wind speed is less than 0.35, GMP must be replaced. The air volume of the cleanroom is 60% -80% of the rated air volume. One parameter is the resistance, the resistance test is too […]

There are too many factors affecting the service life of the high efficiency filter (such as the humidity of the workshop, the dust, the continuous / intermittent operation mode of the air-conditioning system and the maintenance of the plant and facilities). The GMP standard seems to be difficult. No specific requirements. It is recommended to […]

1. Regular annual testing of clean air volume, as well as other environmental parameters, in the determination of the efficiency of the test at the same time. In this case, 2. The main detection of wind speed, the final resistance and leakage rate. In this case, 3. When the high-efficiency air filter air volume decreased […]

What is the HEAP high efficiency filter? HEPA is a commonly used filter equipment, a classification, is a standard, to reach the HEPA standard filter on 0.1 micron and 0.3 micron power can reach 99.97%. Today, we take a look at the details of the use of HEPA it! HEAP high efficiency filter is characterized […]

Filter is a drum-type screen filter device. Wastewater is processed into the axial along the drum to radial radial through the screen out of water impurities that are retained in the drum on the inner surface of the filter. Micro-filter is a drum-type screen filter device. Wastewater is processed into the axial along the drum […]

Vibrating Screen Principle Process: Screening: granular material through one or several layers of mesh to size according to the size of a number of grades into the process. Screening the main tools: screen, the screen has a certain size of the sieve to complete the classification task. Screening: The material that is sieved on the […]

1, punching nets, stainless steel punching nets black steel punching nets circular punching nets punching nets is the same material marked with different shapes of the hole. To adapt to different needs. In this case, Punching net with the raw materials are mostly: stainless steel low-carbon steel plate galvanized PVC cold rolled coil. Types are […]

Screening, according to the nature of the material, will produce a variety of forms of mesh plug. The main reasons for the plugging of the sieve are as follows: (1) contains a large number of particles near the separation point; (2) material moisture content is higher; (3) spherical particles or sieve with multiple contact points. […]

Air filter is a technology development trend, the air filter is currently in all walks of life in the use of more and more widely, with the technical diversity of the development of air filters will stop for a variety of reasons , Today we simply analyze the reasons for the work of the air […]
