Filter Bag Specifications

Filter Bag	Size (mm)	Flow Rate (m³/h)	Filtration Area (m²)	Capacity (L)
No. 1	180 × 430	20	0.24	8
No. 2	180 × 810	40	0.48	17
No. 3	105 × 230	6	0.08	1.3
No. 4	105 × 380	12	0.16	2.6
No. 5	150 × 550	20	0.24	8

Among all sizes, the No. 2 filter bag is the most commonly used.

The listed flow rates (in m³/h) are based on ideal conditions — that is, at one standard atmospheric pressure, with water at a temperature of 25°C and a viscosity of 1 centipoise.

Filtration Precision:

The filtration precision of filter bags typically ranges from 0.5 to 2500 microns (μm).
Common micron ratings include:
0.5, 1, 5, 10, 25, 50, 75, 100, 150, 200 μm.

When selecting a filter, it’s important to clearly understand the required filtration level.

If the micron rating is too large, impurities may not be effectively removed.
If the micron rating is too small, it can cause reduced flow rate and shorten service life.

Therefore, the appropriate micron rating should be selected based on your actual working conditions and filtration goals.
