About Filter

Whether it is in order to ensure a healthy and comfortable indoor air to create a clean production operating environment, or in order to prevent leakage of hazardous substances, select a suitable air filter is extremely important. In general, the final stage of the air filter determines the cleanliness of the air supply, and therefore, the final stage of the air filter in the whole filter process is very important and should focus on the protection,Chemical filters when we choose a filter, it should be based on specific circumstances reasonable choice of suitable air filters, here, we have to follow the following principles.

Optional air filter principle: According to the requirements of clean-room standards, to determine the final stage of the air filter efficiency

Indoor requirements in general, you can choose the early effect filter; if the room requires moderate purification efficiency and should be used early in effect two filters; if the room clean purification requirements, you can use at the beginning, middle and high efficiency three purification filtration and to reasonable levels of efficiency of the filter to match the adjacent filter efficiency levels should not differ too much.

Optional air filter principle: correct determination of the amount of dust and dust features indoor and outdoor air

Filtration process is essentially filtered outdoor air into the interior of such a process, therefore, the amount of outdoor air dust is a very important data. Especially when dealing with multi-stage purification filter, the choice of a pre-filter should want to use environment, energy consumption and other factors make a decision after consideration.

Optional air filter principle: the right to determine the characteristics of the filter

General characteristics of the filters mainly refers to:Carbon filter product filtration efficiency, resistance to penetration, dust holding capacity, filtration velocity and air volume and so on. When selecting a filter, you should use as efficient as possible, low resistance, large dust capacity, filtration velocity is moderate, process air volume, low cost filter, needs to consider a one-time investment and a secondary investment and energy efficiency.

Optional air filter principle: the analysis of the nature of dust and gas

Certain features of dust and gas will affect the use of the air filter, air filter related to the nature of the dust and gas are: temperature, humidity, and the amount of acid-containing organic solvents. This is because some filters allowed to work at high temperatures, while others filter only at normal temperature and under normal humidity environment work, and pH and the amount of dust and gas of the organic solvent on the performance efficiency of the air filter has a great Impact. Therefore, in the selection of the filter before the first of the dusty gas should be analyzed, and then consider what kind of filters that use.See more at:Combination filters,Pleated Metal Mesh Filter
