FILTER MEDIA

Features
- Polyester fiber forms a density gradient (밀도구배) of certain thickness making an effective filtration for particulates when a large quantity of air flow through porous openings.
-Resistance to flame can be add, preventing conflagration and can be cut off as in roll or sheet.
-Frequently used in air filtration, car, various filter for painting booth exhaust and pre-filter in factories.

PRE FILTER(Panel, Bending)

Features
- Normal n-woven fatrics or Flame resistant n-woven fatrics as media
- Prolongs the life of Meidum, Hepa Filter
- In the case of bended-shpae Media, the filtration area and the efficiency of filtration is large and also long-lived. Therefore, it is cost-effective
- Panel type is also cost-effective as it is easy to change media and the maintenance cost is low.

PRE FILTER(BAG)

Features
- Remaining non-woven fabric(부직포여재) in form of a pocket increases the filtration process capacity by a factor of four when applied to the same amount of area.
- Ranaining non-woven fabric(부직포여재) with density gradient (밀도구배) has large filtration capacity and lasts long.
- These air filters are used in hospital buildings, paint booth, Electrical Industry, precision machines and pre-processes.

MEDIUM FILTER

Features
- on the basis of colorimetric method(배색법), it has the filtration efficiency of 60 - 90%
- Used for pre-processes of HEPA FILTERS in Clean Room and Precision Machine Industry.
- Also used as the final filter for air filtration in buildings and factories.
- Can be selected from Polyester, Polypropilen-e, Glass Fiber, Aluminum and Carbon Acrylic depending on the temperature and the characteristics of particulates.

HEPA FILTER

Features
- Over 99.97% filtration efficiency at DOP 0.3㎛ particle.
- Area of Media can be extended appropriately so that it is suitable when significant amount of wind handling is required.
- High-temperature Hepa Filters can stand up to 180℃ under direct heat and 250℃ under non-direct heat.
- Can be selected from Polyester, Polypropilen-e, Glass Fiber, Aluminum and Carbon Acrylic depending on the temperature and the characteristics of particulates.
