How to identify the color of the medium effect bag filter

Medium efficiency bag filter is very common in the use of central air conditioning units, especially in the collective air supply system, some primary filter systems are also equipped, and the annual market demand is still a lot. The key to its purchase includes many aspects, one is to look at the parameters, such as the level of rated air volume, the size of the dust content, and whether the detection data is the same as the industry specification.

Medium effect bag filter can be used for intermediate filtration of air conditioning system to protect the system below the filter and the system itself, in the place where the air purification and cleanliness requirements are not strict, the air treated by the medium effect filter can be directly sent to the user. Aluminum frame medium effect bag filter adopts high quality synthetic fiber melt-blown cloth material or imported glass fiber as filter material, aluminum alloy profile outer frame, internal spray plastic cold-drawn wire support frame. The filter material generally used is three kinds, composite non-woven fabric, imported or domestic synthetic fiber melt-blown fabric material and glass fiber. Each filter bag has a different color, the initial effect is G3-G4 are mostly white, the middle effect is F6 green, F7 pink, F8 yellow, subhigh efficiency F9 has white and dark yellow.

The main material of the medium effect bag filter is melt-blown cloth, which is the core material of the mask. The melt-blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 ~ 5 microns. The microfibers with a unique capillary structure increase the number and surface area of the fibers per unit area, so that the melt-blown cloth has good filterability, shielding property, adiabatic property and oil absorption. Can be used in air, liquid filtration materials, isolation materials, absorbing materials, mask materials, thermal materials, oil absorption materials and wiping cloth and other fields.

There are many kinds of filters, and the filters used in different occasions will be different. Therefore, it is also important to understand the level of a medium effect filter. Medium effect bag filter in the air filter belongs to F series filter, F series filter is divided into bag type and non-bag type two, including bag type F5, F6, F7, F8, F9. If you want to choose to buy or consider the cleanliness of environmental requirements, the effect of the initial effect and high efficiency together is also better, remember to choose a quality guaranteed air filter brand manufacturer to buy.
