Cartridge Filter

Rainbow in a variety of pre-treatment cartridge filter and filter housing, fibrous materials for manufacturing and customer and context-sensitive solutions.

Wound Filter



Features
  • Wound in precise tension from core to surface in diamond pattern by robing method approved by international standard
  • Offer the most precise and efficient filtration for dusts at 0.5μ - 150μ
  • High particle collection efficiency from normal density division that collects particles by size from the surface to the core

Use
  • Industrial water, coating, dyeing, chemical industry, food industry, medicine industry, etc., internal/external diameter, filtration diamete
  • Length 250, 500, 750, 1000(㎜)
    internal/external diameter 30ø(㎜), 60~63ø(㎜)
    filtrationdiamete 0.5, 1, 5, 10, 25, 50, 100, 150, 200, 300(μ)
    material Media Polypropylene, Cotton, Acryl, Binder
    Core Polypropylene, STS304, STS316

Depth Filter



Features
  • Filter using deed filtration method that winds the polypropylene fabric from the core by thermosetting method (felt type)
  • Compression filter (melt blown type) that uses the deed filtration method and melt blown production method
  • Highly efficient in medicine filtration since it does not use additives
  • Suitable for precision filtration because there is not fiber leakage from the filter

Use
  • Industrial water, coating, dyeing, chemical industry, food industry, medicine industry, etc.
  • Length 125, 250, 500, 750, 1000(㎜)
    internal/external diameter 30ø, 60~63ø
    filtration diamete 0.5, 1, 5, 10, 25, 50, 100
    material Media Polypropylene, Cotton, Acryl, BinderMedia & Core Polypropylene

Carbon Filter



Features
  • Prevent arsenic acid of carbon particles by winding the PP filter cloth on the outside of polypropylene core
  • High absorption efficiency in coating filtration, gas and air because it secures the implementation of precision filtration
  • Use NSF approved high-purity and high-uniform substances [NSF : US organization for establishment of public health standard, related education, product certification and risk management]

Use
  • Air purification : Remove the smell of poisonous gas
  • Food industry : decolorization, deodorization, refinement of food
  • Petrochemistry : refinement of raw materials and intermediary goods
  • Plating industry : filtration of coating solution
  • Water : elimination of taste, smell, color and organic matters of water, purification of collected water

Fiberdyne Carbon Filter



C155 Series

Features
  • Wrapped by the obtrusive golden net
  • Not containing cellulose
  • Not containing sulfur
Application
  • The most appropriate choice for a regular or periodic filtration for acid or copper sulfide solution
  • Utmost filter that can handle every materials with one cartridge despite the application area

C-232 Series [ Low-density activated carbon external diameter 2-5/8" & 2-3/4" ]

Features
  • Efficiently remove the chlorine chemical, strange taste and colors
Application
  • Highly efficient for water purification

C-234 Series [ Low-density activated carbon external diameter 2-5/8" & 2-3/4" ]

Features
  • Dual filtration from truedepth structure from wet-forming manufacturing method
  • Composed of the precisely pulverized carbon particles and mixed substances of synthetic fiber of utmost pore size; able to purify the solution and collect the maximum amount of foreign substances
  • Filtration material is fused by heat treatment method. C-234 is a filter without cellulose to prevent the decline of quality due to the microorganism such as a bacteria.
Application
  • The most common filter for treatment of water and industrial water

Bag Filter



Features
  • Proper for large-scale filtration since it has a larger amount of filtration flow and less pressure loss than the cartridge type
  • Easy to dispose of because the polluted matters are collected in a filter bag
  • Easy to replace the bag

Use
  • Industrial water, coating, dyeing, chemical industry, food industry, medicine industry, etc.
  • SIZE *11 : 180øX430L(0.25㎡)
    *12 : 180øX810L(0.5㎡)
    MATERIAL P.P, P.E, Nylon
    degree of filtration 0.5-1200 Micron

FSI Bag Filter



Features
    Material Polypropylene
    Size 7" X 16", 7" X 32"
    Filtration diameter 1, 5, 10, 25, 50, 100

High Flow Cartridge Filter



Features
  • High loading capacity for long life and lower cost filtration
  • Fewer cartridges for fewer change-outs, thus less labor cost
  • O-ring design cause no bypass to ensure the filtration efficiency
  • Easy handling result in less manpower
  • Wide chemical compatibility for different applications

Use
  • Amines
  • Acids and bases
  • Beer and wine
  • Bottled water
  • Carbon beds
  • Completion fluids
  • Deep wells
  • Desalination
  • Dl resins
  • Edible oils
  • EDM fluids
  • Glycol
  • Groundwater clean-up
  • Machine coolants
  • Organic solvents
  • Photo Chemicals
  • Plating solutions
  • RO membranes
  • Ultrapure water
  • Waste water

Pleated Filter



Features
  • Pleated filter is a precision filtration filter that has a wide filtration extent with continual pleated structure and low differential pressure.
