Superabsorbent Ultra Thin Cores for


Our superabsorbent laminates for filtration are designed for use by manufacturers and designers of filtration, separation, coalescing, and dehydration systems. Gelok Water Absorber Filter Laminates can enhance filtration system efficacy by selectively absorbing free water present in fuel and oil, including hydraulic oil, insulating oil, gasoline, diesel, jet fuel, and kerosene. When absorbed, the water is locked physically by hydrogen bonding and will not be able to return to the fuel. Removing water results in extended usable oil life, decreased system down time, and ultimately increased life of equipment.

Gelok Low-Profile, Superabsorbent Laminates

Gelok superabsorbent media’s ultra-thin profile and very high absorbency capacity makes it an ideal choice for use in filtration systems for water removal. Absorbency levels can be customized for specific separation and absorbent challenges. Gelok superabsorbent media is easily incorporated into existing systems or into new filtration designs.

Filtration Applications

  • Gasoline
  • Kerosene
  • Diesel fuel
  • Insulating oil
  • Transformer oil
  • Hydraulic oil
  • Turbine Lube oil
  • Quench oil
  • Synthetic oil
  • Phosphate Ester oil
  • Instrument air
  • Process gases

Features & Benefits

  • Three Absorbency Speeds – Slow, medium, and fast absorption rates are available to match the speed needed for your application.
  • Excellent absorbency with ultra thin profile
  • Easily incorporated into existing filtration systems
  • Decreases equipment and system downtime
  • Increases in fuel efficiency
  • Extends the life of critical equipment

Sizes & Absorbencies

  • Customizable levels of superabsorbent polymer offer absorbencies of up to 1,000 g/sq ft water, increasing the amount of time between filter changes.
