Manufacturing Filter bags at Hongyuan Envirotech

PPS filter bags are known for their ability to withstand high temperatures, resist corrosion, and withstand acid and alkali substances. These special filter bags are designed for use in power plants to remove dust and flue gas. They are made from PPS material and are also known as Ryton filter bags.

Key Advantages and Features:

1. The filtration capacity of the system can be increased by 50-150% without the need for major modifications to the dust collectors.

2. The cleaning efficiency of the system is significantly improved by increasing the distance between each bag.

3. The lifespan of the filter bags is extended as the impact on the bags from the cage is reduced, resulting in less fatigue damage.

PPS filter bags, made from PPS needle felt filter fabrics, are the most cost-effective choice for dust collectors in high-temperature working conditions across various industries.

Our PPS needle felt is crafted using top-quality Toray or Toyobo PPS fibers, supported by a PPS scrim. We employ advanced technology and German DILO equipment to ensure the highest quality production. Depending on the specific working conditions, we offer different surface treatments such as water and oil repellency, PTFE coating, and lamination membranes.

PPS needle felt is widely utilized in coal-fired boilers, waste incineration, and coal-fired power plants.
