PPS filter bags are crafted from the high-performance thermoplastic polymer polyphenylene sulfide (PPS), also known under proprietary names like Ryton© or Procon©. These bags are renowned for their exceptional filtration properties, including:
- Outstanding High Temperature Resistance- PPS filter bags can continuously operate at temperatures up to 160°C (320°F), withstanding surges up to 190°C (375°F). This resilience makes them perfect for high-temperature applications such as incinerators, power generation, cement production, and metal processing.
- Superior Chemical Resistance- PPS filter bags are impervious to a broad spectrum of acids, alkalis, and solvents, making them ideal for environments involving corrosive chemicals such as chemical processing and pharmaceutical industries.
- Exceptional Moisture Resistance- PPS filter bags are also resistant to moisture and hydrolysis, making them suitable for high humidity or wet conditions, like those in food processing and wastewater treatment.
- Remarkable Mechanical Strength -PPS filter bags boast high tensile strength and tear resistance, ensuring durability against abrasion and wear. This is critical for applications in industries like mining and construction where high wear and tear are common.
Beyond these excellent filtration attributes, PPS filter bags offer additional benefits such as:
- Extended Service Life -PPS filter bags provide a long service life, even under demanding conditions, resulting in significant long-term cost savings.
- Effortless Cleaning and Maintenance -PPS filter bags are easy to clean and maintain, reducing downtime and enhancing productivity.
- Eco-Friendly Choice - PPS filter bags are composed of recyclable materials, making them an environmentally responsible option.
Aokai PPS filter bags utilize scrim-supported felt exclusively to enhance filtration efficiency and extend the filter bag's lifespan.

Q6. Do you test all your goods before delivery?
A: Yes, we have 100% test before delivery.
Q7. How to choose material for filter bag with good price?
Since every filter has its own characteristics and parameters, when we choose filter material for dust collector filter bag, we have to know the following parameters:
(1) Working temperature
(2) Humidity
(3) Dust diameter
(4) Gas' chemical properties
(5) Dust abrasiveness
(6) Filter's mechanical parameters
Q8. When we produce the filter bags, you need to provide the following sizes:
(1) The diameter of the filter bags / the semi-perimeter of the filter bags
(2) The length of the filter bags
(3) The diameter of CPO and the thickness of CPO on dust collector
(4) The drawing of the filter bags or the sample of the bag
(5) The material of the filter bags
(6) The type of the filter bags: round or flat, the type of the filter bag top: snap cuff or snap ring
(7) The application of the filter bags: cement, asphalt, power plant, chemical, waste incineration, metallurgy, and so on.
