Of late, a noticeable change has occurred in the environmental perceptions related to the issues of atmospheric contamination due to plant exhaust and automotive exhaust fumes.
Additionally, because of improvement in technological evils the industry has come to demand various clean spaces to a growing degree.
In the such background, TOYOBO has developed electret air filter ELITOLON UNIT®, middle and high efficiency air filters, which are able to efficiently collect atmospheric dust.
ELITOLON UNIT® is featured by the use of a dramatic novel air filter which features a dust removal ratio much than one of glass fiber air filter, despite of having a lower pressure drop and good durability. These link to a noticeable improvement in efficiency.
It has broad applications in air-conditioning units for office building as well as industry, and is also in extensive uses as pre-filter for HEPA or ULPA filter placed in clean room.


Featuers
The filter media, a component of ELITOLON UNIT®, is TOYOBO electret filter ELITOLON® U type, which is composed of double layer structure made of electret filter and a non-woven fablic with fiber density gradient.
Generally, air filter made by fibrous component collects atmospheric dust by following mechanism.
  1. Inertial impact
  2. Direct interception
  3. Diffusional deposition
  4. Gravitational setting
In addition to them, collection mechanism of ELITOLON® is based on two electrostatic effects of electret fibers.
  1. Coulombic force
  2. Induced force
The electrostatic effect is kept for a very long time because the electret fibers made of a dielectric synthetic polymer have semipermanent charges.
Because of this composition it displays the following features.
  1. Low pressure drop and low running cost
    Because of electert filter, the amount of fibers needed to improve the collection efficiency is only a few, therefore we can attain low pressure drop.

  2. Long life time and low maintenance cost
    By utilizing with fiber density gradient along the thickness direction of the filter media, we are able to avoid clogging due to dust particles and technical applications were made to reduce increase in pressure drop.

  3. Ease of handling
    Because the filter media is made of synthetic fiber, the strength is higher, it is difficult to be damaged, comparing with conventional glass fiber filter media, there is little trouble in installation and exchange.

  4. Resistance to chemical
    Since the filter media is made of polyolefin fibers, the filter unit endures erosion from acids or alkalis.

Featuers

ELITOLON UNIT® can be roughly classified into three types which are EF-UNIT, SL-UNIT, and FU-UNIT. Each type can be used depend on space or use.
