PET Composited Needle Felt Filter Bag

PET composited, which means that the bag was treated with hydrophobic oil-repellent agents to resist moisture and oil penetration, so we also called that Water & Oil & antistatic resistance filter bag, it is the updated pro edition. The PET composited filter bags are specialized filtration media designed for humid, oily, or adhesive dust environments, preventing clogging and maintaining filtration efficiency.

PET Composited Needle Felt Filter Bag, with its unique material advantages and excellent performance, has been widely applied in multiple industrial fields that require efficient dust removal and meet medium-low temperature working conditions. In the chemical industry, it is an ideal choice for dust control in processes such as fertilizer production, pesticide synthesis, and plastic granulation. The PET composite material of the filter bag has good chemical stability, which can resist the slight corrosion of organic solvents, acidic/alkaline dust (such as ammonium phosphate powder, urea particles) generated in chemical production, and its operating temperature range of -10℃ to 130℃ perfectly matches the temperature environment of most chemical workshops (usually 50℃ to 110℃). Meanwhile, the needle-punched felt structure with high porosity ensures a filtration efficiency of over 99.5% for fine chemical dust (particle size 1-10μm), effectively preventing dust from polluting the production environment and protecting the health of operators.​

• In the mechanical processing and manufacturing industry, especially in metal cutting, grinding, and welding processes (such as automobile parts processing, hardware manufacturing), the PET Composited Needle Felt Filter Bag plays a key role in collecting metal dust (aluminum alloy, cast iron, stainless steel particles) and welding fumes. The surface of the filter bag is treated with anti-static and anti-adhesion technology, which can avoid the adsorption of metal dust caused by static electricity and prevent the blockage of the filter bag by sticky welding fume residues. Its excellent wear resistance also allows it to withstand the long-term friction of hard metal particles, extending the service life to 12-18 months, which is 30% longer than ordinary polyester filter bags, significantly reducing the frequency of filter bag replacement and maintenance costs for enterprises.​
• In the food and feed processing industry, the PET Composited Needle Felt Filter Bag is widely used in dust removal during grain drying, flour milling, and feed granulation. The food-grade PET composite material it adopts meets the national food safety standards (such as GB 4806.6), without releasing harmful substances, and can avoid secondary pollution to food/feed raw materials. For example, in wheat flour processing workshops, the filter bag can efficiently collect wheat bran dust and fine flour particles (filtration efficiency ≥99.6%), reducing raw material waste (saving 2-3kg of raw materials per ton of flour) while ensuring the cleanliness of the production environment and complying with the hygiene requirements of the food industry.​
• In the waste treatment and recycling industry, especially in the sorting and crushing processes of domestic waste and industrial solid waste, the PET Composited Needle Felt Filter Bag is suitable for collecting mixed dust (including plastic fragments, paper dust, and light organic particles). The filter bag has good water resistance and mildew resistance, which can adapt to the humid environment in waste treatment workshops (relative humidity 60%-80%) without mold growth or structural damage. At the same time, its high air permeability (air permeability 10-15m³/m²·min) ensures that the dust collector maintains stable air volume, avoiding the problem of reduced dust removal efficiency due to filter bag blockage, and helping waste treatment plants achieve up-to-standard emission of dust pollutants.​

In addition, the PET Composited Needle Felt Filter Bag also has broad application prospects in the textile industry (collecting cotton fiber, chemical fiber dust), building materials industry (controlling dust in dry mortar mixing and ceramic raw material processing), and electronics industry (removing dust in plastic shell injection molding processes). Its cost-effectiveness, stable performance, and wide adaptability make it a cost-efficient and reliable dust removal solution for medium-low temperature, low-corrosion, and fine dust scenarios in various industries.
