| ● Comparison of Gauze Wire Element and Notch Element |
|
 | | Notch Wire | Gauze Wire |
|
|
Notch Wire Elements are created to utilize an uneven surface which is fightly coiled and is therefore
highly effective in contamination removal. Additionally, the stainless steel wire foes not corrode.

| ● Stainless Mesh & Screen |
|
| ■ Porous Plate |
|
The screen of the filter element adopted to our models has the reinforced porous plate(60 degree) as a supporting plate. The porous plate is generally produced by means of punching. In this case, the relation among the bigger size(diameter), pitch and plate thickness generally make t≤P-d.
If porous plate requires bigger porous ratio against plate thickness, this plate can also be available. |

| ■ Viscosity |
|
Internal frictional force provides resistance to the flow of liquids.
Theoretically, there is absolute viscosity and kinematic viscosity where their mutual relationship is
< Kenematic viscosity in t℃，= absolute viscosity in t℃. / density in t℃. > |
|
|
| 1. | cSt (Kinematic Viscosity |
| indication of kinematic viscosity in C.G.S. units represents stoke, and CSt is 1/100 of stoke. The measuring temperature is 40℃ and 100℃ in the ISO (International Organization for Standards) viscosity classification This classification is universally accepted. |
| 2. | Eº (Engler Viscosity) |
| It is that efflux time of a 200cc sample divided by efflux time of 20℃ water observed at the temperature of 20℃, 50℃ and 100℃ and is mainly used in Europe. |
| 3. | SUS or SSU (Saybolt Universal Viscosity) |
| SUS or SSU (Saybolt universal viscosity) It observes efflux time (in seconds) of 60cc of ubricating oil. The observation temperatures are 100℉, 130℉ and 210℉ and is used mainly in America. |
| 4. | Redwood Viscosity |
| - Redwood #1 : It is efflux time of 50cc sample, The observation temperatures are 30℃,50,80 and 100℃ used
mainly.
- Redwood #2 : Observed efflux lime of 50cc sample in 0℃ |
