What are the main applications for PPS pleated coated filter bags?

PPS pleated coated filter bags are primarily used in high-temperature and chemically aggressive environments such as chemical processing, pharmaceutical manufacturing, and food & beverage industries. They are ideal for liquid-liquid separation, solid-liquid separation, and gas filtration where high temperatures and chemical resistance are required.

How do I determine the correct size of PPS filter bag for my application?

To determine the correct size of PPS filter bag, consider the dimensions of your filter housing and the flow rate requirements of your process. Standard sizes are available, but customization is also an option to ensure optimal performance. Consult with our technical team for specific recommendations based on your process parameters.

What maintenance is required for pleated coated filter bags?

PPS pleated coated filter bags require minimal maintenance due to their durability and resistance to degradation. However, regular inspection for signs of wear and tear is recommended, especially in highly abrasive or corrosive environments. Replacement should be considered when the filter efficiency drops or when physical damage is observed.

Why Choose PPS Pleated Coated Filter Bags for Your Filtration Needs?

PPS pleated membrane filter bags use polyphenylene sulfide (PPS) needle-punched felt as the base material, combined with a PTFE microporous membrane and a pleated structural design, offering excellent high-temperature resistance, resistance to acid and alkali corrosion, and highly efficient surface filtration characteristics. Their continuous operating temperature typically ranges 190°C, with a short-term temperature resistance of 210°C. They are suitable for harsh operating conditions such as sulfur-containing flue gas, high humidity, or acid and alkali corrosion. Additionally, the pleated structure increases the filtration area by approximately 50%–150% compared to traditional round bags, effectively reducing operating pressure drop and energy consumption. This product is primarily used in dust control applications involving high-temperature, sulfur-containing flue gas, such as in coal-fired boilers, waste incinerators, fluidized bed systems, cement kilns, and chemical and metallurgical processes.

PPS material ensures long-lasting performance in high-temperature environments.
Chemical resistance to a wide range of substances makes it suitable for various industries.
Pleated design for increased filtration efficiency and reduced pressure drop.
