Why Efficient Air Filter Resistance Is Very Practical1

With the increasing environmental pollution and the strengthening of people's environmental awareness, air quality has become one of the focus of attention. It is now recognized that air filtration systems not only protect machinery but also protect people. Therefore, the application of high efficiency Air Filter is more and more widely, including the pharmaceutical industry, cosmetics production workshop, hospital, food processing industry, clean room, air conditioner, HAVC system.

But the total cost of clean air system is high, the operating costs of clean equipment accounted for a large proportion of the total cost, for example, the general electronics factory clean room using axial fan shaft air circulation form, if the unit cycle wind energy consumption by 0.236w m3 / h) calculation, electricity is 0.6 yuan, only about 5 million yuan per year to run electricity.

So high operating costs have become the use of efficient Air Filter to promote the obstacles. Can reduce the energy consumption of equipment, that is, to ensure a certain efficiency of the filter under the premise of reducing the resistance of high efficiency Air Filter is the key to solve the problem. Reduce the energy consumption of clean equipment has become one of the current direction of air clean research. Air Filter structure optimization, is an effective means to achieve this goal.

In recent decades, the Air Filter structure design has made significant progress, the most important of which is the development of non-partition Air Filter. Airless filter is a new type of high efficiency Air Filter developed in the 1970s, not only eliminates the risk of damaging the media. But also effectively increase the filter area, improve the filtration efficiency, and reduce the air resistance, thereby reducing the energy consumption.

Non-partition high efficiency Air Filter design starting point is to reduce the structural resistance, while the bag structure of the Air Filter structure resistance is relatively small. The Air Filter structure similar to the YGG type low resistance sub-efficient Air Filter for the filter bag Air Filter, but the experiment is expected to get the best filter bag diameter is much larger than 20mm, and there is no supporting the role of the filter flap , Thereby increasing the flow channel area, reducing resistance. Therefore, the high efficiency Air Filter has a potential market prospects, the test test analysis both theoretical and practical economic significance.

Affect the Air Filter life reasons, in addition to the advantages and disadvantages of Air Filters, there are two reasons:

First, the filter material in the Air Filter is too small or the dust capacity per unit area is too small;

Second, the pre-Air Filter has a low filtration efficiency.

For the first reason, the use of large area of the Air Filter significantly extend the service life, it is best to take this into account when the design, the project is completed after the transformation of the system to extend the life of the system to trouble.

For the second reason, you can adjust the filter efficiency of the Air Filter and keep the dust outside the pre-Air Filter. For example, the end of the filter is F7, the use of G4 pre-Air Filter when the end of the Air Filter life is 3 months; switch to pre-F5 Air Filter after the end of the Air Filter life extended to six months. In the clean room, the value of the end of the efficient Air Filter is not high, but the risk of replacing the Air Filter and the overhead will be high, and the replacement of the pre-Air Filter does not need to be discontinued, so the experienced owner will pay attention and money On a pre-Air Filter.

High efficiency Air Filters installed in a clean room, such as a high efficiency Air Filter in a fully automatic air shower, if the front end of the Air Filter is protected, the service life of a good Air Filter can last up to two years. To clean the high-performance Air Filter on the workbench, we can replace the high-efficiency Air Filter by cleaning the pressure gauge on the workbench. The efficient Air Filter on the clean shed can determine the air speed by detecting the wind speed of the high efficiency Air Filter The best time to replace the filter, such as FFU fan filter unit on the unit of high efficiency Air Filter replacement is through the PLC control system prompts or pressure table tips to replace the efficient Air Filter.
