          Glass-Fiber-Filters-banner.jpg

          As one of the leading enterprises in filtration and a technology driven company, Cobetter focuses on technologies of filtration, separation and purification. For years, we have been committed to providing customers in different industries with various solutions.

          With the rapid development of modern industry and science & technology, environmental pollution is a serious threat to human health and life. In recent years, glass microfiber filters has been widely used in environmental monitoring due to its high flow rate, high retention, high load capacity and ultra-high corrosion resistance. Cobetter has developed various types of glass fiber filters to meet different requirements of customers.

          • · Special hydrophobic treatment, can be used in high humidity environment and still keep the air flow unobstructed.

          • · Various selections of pore size: 0.1-10 μm

          • · Binder-Free Glass Microfiber Filters and Glass Microfiber Filter With Binder for your choice



          Typical Application

          • · PM10, PM2.5 air monitoring filters for gravimetric sampling.

          • · Vehicle emissions testing by β-ray method.

          • · Gas absorption filters,protect and enhance sensor performance.

          • · Determination of automobile exhaust particulate matter by gravimetric method.



          • For different application scenarios, Cobetter can provide three types of glass fiber products, which are filter tape, sheet type membrane and protective filter to meet various requirements of customers.



           Glass Fiber Filter Tape

           Gas Absorption Filter - Protect and enhance sensor performace
          Glass Fiber Membrane cbt(3).jpg   

          In the detection process of gas sensor, the composition of the detected gas is often complex, and it is easy to create cross interference between different gases. For example, for gas sensor that is indicated to detect carbon monoxide, hydrogen could be also on the gas sensor if hydrogen’s concentration is high in the test environment. Then hydrogen may also react and get a signal that the concentration of carbon monoxide is higher than the actual volume.


          In order to reduce the interference of some non-specific gases in air detection process, Cobetter glass fiber membrane with special treatment can absorb some interfering gases in the air, such as H2S, HDMs, etc.


          Characteristics
          · Rapid diffusion speed.
          · High adsorption capacity.
          · Efficient adsorption for interfering gases.
          · Low chemical background, no adsorption on detected gas.
          · Provide customization with a variety of specifications and treatment options.
          Please consult sales representative for more details.



           Protection Filter

          Cobetter protection filter can filter particles and prevent water from entering the terminal precision detection equipment, so as to increase equipment’s life time. 


          · Welding and assembling filters in 10,000 Class Clean Room. 
          · Various filter sizes and connectors are available.
          · A variety of pore sizes for selection.
