Primary panel filters are generally only suitable for primary filtration of air conditioning systems, and it is mainly used for particles above 5μm.Primary filterGenerally divided into three styles, respectively, plate type, folding type, bag type. These three filters are used more often is the primary effect plate filter.

The main features of the plate primary filter:

Flat plate filter filtration efficiency 30%, 40%@1m (calculation method) or European normative standards G3, G4. The outer frame is as follows: galvanized sheet, aluminum profile; the filter is non-woven, polypropylene fiber material. The internal frame of the filter is sandwiched with plastic grids on both sides to prevent deformation of the filter. The filter can be replaced and cleaned. Its advantages are compact structure, light weight, low resistance and easy installation.

What should be considered when installing a primary panel filter:

1, for the new primary plate filter, before use, it is good to use a special cleaner to clean it, in the process of using the cleaner, it is good to avoid acid cleaners. After the initial effect plate filter cleaning, you also need to use high temperature steam to sterilize and disinfect it, after cleaning the equipment also need to make it a particularly appropriate placement.

2, in the installation of the good is to pay attention to the direction of the export, the technicians told us that the export direction of the primary effect plate filter can not be reversed, you need to pay attention to the mouth of the base plate is certainly the inlet, the cartridge socket tube is certainly the outlet place. Load the cartridge when it is good to it vertically, when you inserted after the need to use the pressure plate to buckle the tip of the warps, and then the screws can be twisted.

3, in the use of equipment when the pressure is good to maintain it at 0.1MPa or so, when the use of time growth and flow increase is likely to be slightly clogged phenomenon. In the process of using, also need to pay special attention to, the pressure is good not to exceed 0.4MPa, or its filter element is very easy to damage. The pressure gauge of the primary plate filter is the pressure of the liquid, if it is the second stage of filtration, then his priority filter pressure gauge index will be smaller. The longer the use of this equipment, its pressure will become greater, the flow rate will be slower, if such a situation occurs, it means that its cartridge has been clogged, which requires it to be replaced in a timely manner.

In order to ensure the purification effect and filtration function, the flat panel filter should be regularly checked and replaced during the use.

Whether there is any damage to the plastic mesh, whether there is any debris blocking the inlet surface, whether the surface of the filter is broken, etc. are all the problems we need to pay attention to during the inspection process of filter use. And, even if there is not a little damage, generally speaking, it is best to use the flat panel filter for about half a year. Of course, the higher the concentration of dust in the environment, the life cycle of the flat panel filter will be reduced.
