Multi ring filter bag

Multi ring filter bag

We can also develop various non-standard products according to customer requirements.

　　Multi ring filter bag(usually referring to the filter bag design in multi bag filters) has advantages in the field of industrial filtration, and its core characteristics and applications can be summarized as follows:

1、 Main advantages

1. Efficient filtering and processing capabilities

The multi bag parallel design significantly increases the filtration area, with a single machine processing capacity of up to 1080m ³/h and a unit flow efficiency 5-10 times that of the filter element.

The three-dimensional filtering layer structure enhances the particle capture ability, with an accuracy coverage of 0.5-1200 μ m, and the filter bag material (such as PTFE, PESU) can be adapted to different media requirements.

2. Economy and maintenance convenience

Compared to equipment such as plate and frame precision filters, it has lower investment costs and faster filter bag replacement (30 second quick opening design), supporting acid and alkali cleaning and reuse.

Fluorine lined materials (such as PTFE) are corrosion-resistant and heat-resistant (-20~200 ℃), extending their service life and reducing maintenance frequency.

3. Wide adaptability

Diverse materials (stainless steel 304/316L, polypropylene, etc.), capable of handling strong acids, strong alkalis, high viscosity, or high-temperature media.

Low wind resistance design reduces energy consumption, such as reducing fan energy consumption by 12% in food factory applications.

2、 Typical application areas

1. Chemical and Pharmaceutical Industry

Handle corrosive liquids (acid, alkali, salt solutions) and biologics to meet GMP and FDA standards.

2. Food and Electronics

Filtering of food raw materials (such as dairy products and beverages) and purification of high-purity reagents in the electronics industry.

3. Environmental Protection and Energy

Industrial wastewater treatment and high-temperature gas dust removal, with a pressure resistance of up to 2.5MPa.
