Liquid Filtration and Solid-Liquid Filter Bag

Qingdao Star Machine Technology Co., Ltd. specializes in custom liquid filtration and solid-liquid filter bags. Our filter bags are specially singed to stop fibres from shedding and to stop the filtrate from contaminating the bag. This also stops the bag from clogging too much, which would otherwise shorten the bag's lifespan.

Why Choose Our Liquid Filtration and Solid-liquid Filter Bags?

✔ Eco-Friendly & Safe – Made from high quality PP/PE raw materials with no bleaching or dyeing, meeting environmental standards.

✔ Efficient Filtration – The needle felt’s 3D filtration layer captures solid and colloidal particles effectively.

✔ Durable & Long-Lasting – Uniform thickness, stable pore size, and high-strength materials ensure long service life.

✔ Free Samples Available – Contact us to request a sample and experience the quality firsthand!

Our filter bags are perfect for all kinds of industrial filtration jobs, and you can count on them to perform reliably.

Product Feature And Application

1.The Ultrafine fibre High-efficiency Liquid Filtration and Solid Liquid Filter Bag, also known as the AGF Liquid Filtration and Solid Liquid Filter Bag, is manufactured to meet the increasingly strict requirements of the filtration industry. It uses pure fully welded sealing and filtration technology, pushing industrial technology to another level and leading bag filtration to a new level. The filter material of the ultra-fine fibre high-efficiency liquid filtration and solid-liquid filter bag is pure polypropylene, which has good lipophilic and hydrophobic properties, and no other chemical components are generated during the filtration process. The filter bag is designed with an inner layer coarse filter surface and an outer layer fine filter surface. The inner layer makes sure there's enough space for dirt, reduces resistance, and the outer layer catches small particles to make sure the filtration is accurate. The cascade design makes sure that impurities are caught one layer at a time. The ultrasonic welding technology makes sure everything is sealed really well and there's no leakage.

2.Corrosion resistant Liquid filtration and solid liquid Filter Bag PP filter bag, also known as polypropylene filter bag, is composed of pure polypropylene fiber filter cloth and belongs to a type of liquid filter bag. Polypropylene is a non-toxic, odorless, and tasteless milky white high crystalline polymer with a density of 0.90- 0.91g/cm3. It is particularly stable for water, with a water absorption rate of only 0.01%, with a molecular weight of approximately 80000 to 150000. The liquid filtration and solid-liquid filter bag has good form-ability, good aging resistance, chemical properties, almost no water absorption, and does not react with the vast majority of chemicals. The use of acupuncture to create loose fibrous tissue and increase impurity loading space belongs to the compound interception mode. Its internal honeycomb structure effectively removes solid and soft particles, meaning that larger particle impurities are trapped on the surface of the fiber, while fine particles are captured in the deep layer of the filter material. During use, it will not be damaged due to pressure increase, and has high filtration efficiency.

3. High temperature and acid resistant Liquid filtration and solid liquid Filter Bag is PTFE Liquid filtration and solid liquid Filter Bag. The filter bag continuously operates at a temperature of over 250 degrees Celsius, with an instantaneous temperature of 280 degrees Celsius. It is not afraid of acid, alkali, and oxidation, and is almost non combustible and will not age. Meet harsh working conditions and have an extremely long service life.
