Industrial Filter Paper
In order to use in diverse production sites, its filtration flow and burst strength are reinforced. It has a thickness of about 0.2 to 2mm. As they are made of natural cellulose pulp, they are widely used in chemical, beverage and medical fields.
Classifications Of Filter Papers
High Purity Filter Papers
These are basically used in quantitative analysis or chemical experiments.
As they contain less ash and less impurities, they are used for general industrial filter paper.
Standard Filter Papers
The most common filter paper for clarifying filtration, With qualitative filter paper for analysis, it collects particles of 1~10㎛ effectively.
Wet Srrength Filter Papers
With special treatment, wet strength is enhanced.
Crepe Filter Papers
With the surface of uniformly crepe, the filtration area is enlarged. Efficiency is improved without reducing filtration speed.
Craft Filter Papers
Made of whitening cellulose fiber with no bleaching treatment, light brown surface
HA Series
The most common filter paper used for Clarifying Filtration. Used for horizontal or vertical pressure type filters. Widely used in many fields. Three types within a range of 1~4㎛ which are commonly used in production sites
retention (㎛) | filtration speed (s/100ml) |
thickness (mm) | basic weight (g /㎡) |
grade | Classification |
۱ | ۲.۵ | ۰.۵۷ | ۲۴۰ | HA-010 | Standard |
۳ | ۲.۵ | ۰.۸۴ | ۳۰۰ | HA-030 | |
۴ | ۲.۵ | ۱.۰۸ | ۳۸۰ | HA-040 |
HC Series
Similar shape with HA series but this is thicker with higher burst strength than HA series. Suitable for production under strong pressure. Suitable for production with relatively high pressure, The retention rate is in the range of 1 to 6㎛ which provides a wide range of choice.

۶ | ۱.۰ | ۰.۲۸ | ۹۳ | HC-060 |
HU Series
The highest density and the strongest hardness among industrial filter papers, less fiber breakaway, Suitable for removal of fine solid matters Products for diverse purposes: wet strength, crepe and craft filter papers

- Filtration speed ( sec) : By using Herzberg filtration speed tester, filter 100ml of water at 20℃ to an area of 10㎠ with pressure
of 100mH20. The time is measured during filtration.
This has almost accurately correlated to air permeability. - Burst strength ( kPa ) : Burst Strength is determined by Mullen Burst STRENGTH Tester in accordance with JIS P8112.
The strength when filter paper bursts by applying force on filter paper with rubber film. Filter paper maintains its strength due to tangled fiber and H2 bond.
When it is soaked in water, the hydrogen bond is destroyed and the strength is lowered.
However, the strength of wet-strengthened product is not lowered as much when it is soaked in water. - Retention rate ( ㎛ ) : Retention rate is determined by the particle size of the precipitated.
When liquid mixed with evenly distributed dust (7 types of JIS Z8901) is filtered in a consistent condition,
this value is measured when the particle efficiency is 90%.
