Sterilizable 121.C 50mm Circular Filter Paper 15bar Pressure Resistant Low 0.5bar Drop HME Filter Paper

Product Description:

The Bacterial Viral Filter Paper is a high-efficiency filtration product designed to provide maximum protection against bacterial and viral contaminants. It is an essential component for environments where sterile conditions are critical, such as medical facilities, laboratories, and pharmaceutical manufacturing. This advanced virus filter cotton has a robust construction that can withstand a variety of demanding conditions, ensuring that the integrity of your processes and products is never compromised.

One of the key attributes of this filter paper is its exceptional Filtration Efficiency, which stands at 99.99%. This level of efficiency, denoted as VFE>99.99%, indicates that the filter can effectively remove nearly all virus and bacteria particles from the air or fluids passing through it. This is particularly important in preventing the spread of airborne diseases and maintaining the purity of sensitive environments.

The Bacterial Viral Filter Paper is engineered to operate safely under high-pressure conditions. It boasts a Max Differential Pressure of 15bar, meaning that it can sustain significant pressure differences across its surfaces without compromising its structure or performance. This is critical for systems that experience fluctuations in pressure, ensuring that the filter maintains its integrity and continues to protect against microbial contamination.

Furthermore, the filter is designed to endure a Max Operating Pressure of 30bar. This high threshold indicates that the filter paper can be used in high-pressure applications without the risk of rupture or failure. Whether it's used in industrial-scale filtration systems or in high-pressure research apparatus, the Bacterial Viral Filter Paper is built to perform reliably under pressure.

Sterilization is a vital process for any component involved in filtration, particularly when it comes to the stringent standards required for filtering viruses and bacteria. The Bacterial Viral Filter Paper can withstand a Max Sterilization Pressure of 2bar, allowing it to be effectively sterilized using high-pressure steam without losing its structural integrity or filtration capabilities. This makes it easy to maintain a sterile environment and ensures that the filter can be reused in settings where sterilization is a routine requirement.

Temperature can also play a critical role in the performance and longevity of a filter. Our Bacterial Viral Filter Paper is designed to operate at a Max Operating Temperature of 100℃. This high-temperature threshold ensures that the filter can be used in a variety of applications, including those involving hot gases or liquids, without degradation of the filter medium or a reduction in its filtration efficiency.

The virus filter cotton used in the construction of this filter paper is not only highly efficient but also robust and versatile. The material's innate characteristics contribute to the overall durability and efficacy of the filter, making it an ideal choice for critical applications where reliability is paramount. With VFE>99.99%, users can trust that they are receiving the utmost level of protection against viral and bacterial transmission.

In conclusion, the Bacterial Viral Filter Paper is a superior filtration solution that combines high efficiency, strong pressure resistance, and impressive temperature endurance. It is perfectly suited for a wide range of applications where the utmost in cleanliness and sterility is required. With its virus filter cotton's exceptional performance, you can be confident that your processes and environments are safe from contamination, ensuring peace of mind and reliability in every use.
