Glass Fiber Membrane Filters

Microporous Glass fiber filter membrane is chemically inert and usually contains no binder. It is made of 100% borosilicate glass fiber and has a capillary structure to absorb more water than the same cellulose filter papers do. The membrane filter has the characteristics of fast flow rate, high-temperature resistance, superior hydrophobicity, biological inertness, and strong dirt holding capacity, and can filter fine particles. Glass fiber membrane filters have higher filtration efficiency, in contrast to other fiber materials and synthetic materials. As an important part of FRP products, glass fiber is widely used, and the application of filter film is closely related to our daily life.  This membrane belongs to deep filtration. Their main purpose is to use as a filter layer and directly on the membrane filter. Glass fiber filter membranes are used for routine monitoring of air pollution monitoring and special monitoring of solid contaminants, microorganisms, oils and acid mist in the air. It can also collect highly efficient fine particles for water pollution analysis. It is an ideal product for collecting dust in the air and accurately measuring it. It can be used for pre-filtration of membranes to prevent clogging of membranes; large surface area uses glass fiber membranes for excellent retention.

Different sizes of filters have specific requirements on the diameter of the pre-filtration membrane. If the diameter is too large, its edge will extend under the sealing ring and cause leakage. When filtering more viscous and difficult to filter the liquid, it is usually used in the multi-layer filtration method, 2-3 layers of filter membrane with different pore sizes stacked, polyester separation layer added between the filter membrane for the convenience of liquid filtration, the top layer with glass fiber pre-filtration membrane.

In our company, we have two types of this filter: with binder and without binder. So when you are going to buy it, you should know the type you need.

Pore size : 0.7um /1.2um
Diamter : 13/25/47/50/60/90/100/106/120/142/150/200/250mm.

Used for the collection of high-efficiency fine particles and the analysis of water pollution. The accurate determination of the ideal supplies. Can be used for membrane pre-filtration to prevent membrane blocking; Glass fiber filter membrane with the large surface area has excellent interception ability. Microporous glass fiber membrane filters without binder has a capillarity fiber structure, which makes it possible to absorb more water than other cellulose filter papers do.

Microporous glass fiber membrane filters with a binder are often used for environmental analysis, determination of PCB, DDE, DDT, furan, dioxin content in the air. Measure dust in a cement plant and steel plant. Determine dust composition in industrial gases and test the efficiency of dust collection.
