STRUCTURE of Nanofront® FELT

Nanofront® felt is composed of 2 layers, Unique Nano fiber Sheet and Base felt.

1. Nanofront® Sheet

  • By dispersing even diameter of Nano fibers, achieves high dust collecting efficiency.
  • By dispersing thicker diameter of fibers, it makes possible to keep even porous and high air permeability (low pressure loss) → SAVE ENERGY
  • High dust collecting efficiency can prolong time to clogging → LONGER LIFE

2. Base felt

1: Nanofront® Sheet
2: Base felt

TEST EQUIPMENT OF FILTRATION EFFICIENCY

In order to assure our assumption, we implemented test to analize filtration efficiency.

JIS Z 8909-1
Test items:shifting of pressure loss, pulse interval, amount & ration of dust emission

TEST RESULT VS. PTFE MENBRANE FELT AND ASSUMED REASON

Test result in labo

[A] Initial pressure loss, successive residual pressure loss

Nanofront® Felt < PTFE membrane

Analysis

surface

cross section

[B] Dust collecting efficiency

Nanofront® Felt ≒ PTFE membrane

Assumed reason of the result

[A] Surface of Nanofront® Felt is composed of fiber. Therefore there is no film-like area 1 and porous is not so microscopic as compared with PTFE membrane. 2

[B] Because Nanofront® Sheet is fiber layer, it is not so thin as compared with PTFE membrane 3 therefore no hole which sometimes appears in PTFE membrane. 4
