The difference between laminar flow pass box and air shower pass box
The difference between laminar flow pass box and air shower pass boxA Laminar flow pass box is a kind of pass box, which is named a self-cleaning pass box because of its air purification function. A Laminar flow pass box is installed with a centrifugal fan and liquid tank filter, which can purify the air and objects inside the pass box, and make the transferred objects and the air inside the pass box achieve a high cleanliness level. It plays a key role in certain places of use with high cleanliness requirements, not only maintaining a high cleanliness environment without lowering the cleanliness level during the transfer of objects but also reducing the source of contamination on the surface of the product itself.Cleanliness level demand for higher places into the clean room objects including raw materials and auxiliary materials, etc., have more stringent requirements, first of all, to ensure that the product in the clean room process is not contaminated, and at the same time also need to complete the purification of the product to reduce the clean room into the clean room objects to the clean room cleanliness level of the impact of the two aspects of the self-purifying effect of the existence of the pass box appears to be very critical. A Laminar flow pass box is installed with a liquid tank high-efficiency filter, which can circulate and purify the air inside the pass box to maintain a certain level of cleanliness. When using the laminar flow pass box to transfer objects, try to let the objects stay in the pass box for a while to ensure that the dust on the surface of the objects is completely purified. Air shower pass box Air shower pass box is another type of pass box, with the basic function of blowing shower, It is different from the laminar flow pass box, not through the top of the homogeneous flow membrane downward conveying airflow, but through the nozzle to the pass box blowing clean air after filtration, the airflow speed is faster, usually about 25m/s, and laminar flow pass box airflow speed is usually in the laminar flow pass box between 0.35 ~ 0.45m/s. Wind shower pass box on the pass box internal airflow and transmission of goods purification processing speed faster, shorter processing time, in some short-term need to transmit more items of the occasion is more practical, that is, to save transmission time, but also to ensure that the transmission of the cleanliness of the goods. Above, we summarise the basic concepts and differences between the medical pass box, laminar flow pass box, air shower pass box three pass box. Medical pass box is classified according to the use of place, laminar flow pass box and air shower pass box are classified according to the basic principles and basic functions, the three pass boxes' main function is to reduce the number of times the door is opened, reduce the outside world on the inside of the clean room environmental pollution. |
