Knowledge! Types of Fresh Air System Filters

The function of the new air system in addition to ventilation, the most important function is to filter the pollutants in the air, so the filter of the new air system is the most important part of the whole system.

Nonwoven filter: the scientific name of polyester fiber, commonly known as nonwoven fabric, nonwoven fabric has a wide range of use, technical maturity, stability and other technical characteristics, is China’s current initial and intermediate effect plate, bag filter typical filter material. Manufacturing process to meltblown, needle punching, spunlace, spunbond and other processes made through multiple processes, compared with other filter media of the same level has a stable quality, greater dust capacity, moisture resistance, long service life, economic durability and other advantages. Nonwoven fabric is also the earliest application of filter materials, in recent years, due to the continuous technology, the emergence of composite nonwoven fabrics to greatly improve the image of nonwoven fabrics of cheap and low-grade, in the efficiency has been able to achieve sub-high efficiency.

Fiberglass Filter Mesh: Fiberglass filter mesh is mainly made of various kinds of thick and thin, long and short glass fibers by special processing technology. Glass fiber is characterized by its stable performance, high temperature resistance, high efficiency and large capacity, and long service life. And in some special environments also only the wave line can be competent. It is widely used in primary filters, high-temperature resistant filters and high-efficiency filters in general ventilation systems.

Synthetic Fiber Filter: It can fully replace non-woven fabric and glass fiber in general filtration environment, covering the whole series of coarse, medium and high efficiency filtration products, which is an emerging filtration material and the main development direction of future filtration materials. Compared with other filter materials of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection (incineration) and moderate price.

Photocatalyst filter: nanometer titanium dioxide photocatalyst as raw material, combined with the latest technology to make the photocatalyst with the smallest particles uniformly attached to the surface of different substances photocatalyst is sunlight, fluorescent lamps, ultraviolet light as an energy source, excitation of electrons on the valence band (e-) leaps to the conduction band, in the valence band produces the corresponding holes (h +), generating activated oxygen and hydroxide radicals with strong oxidation effect, formaldehyde, methylamine, Formaldehyde, methylamine, benzene, xylene, TVOC and other harmful organic compounds, pollutants, odor, bacteria, etc. oxidized and decomposed into harmless CO2 and H2O, to achieve the purpose of purifying the air and decomposing harmful organic compounds.
