Gelok Superabsorbent Laminates for


Our superabsorbent laminates for filtration are designed for use by manufacturers and designers of filtration, separation, coalescing, and dehydration systems. Gelok Dewatering Filter Laminates selectively absorb free water present in fuels, including hydraulic oils, 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 as well as decreased system down time and ultimately increased life of equipment.

Features & Benefits

  • Three Absorbency Speeds – Slow, medium, and fast absorption rates are available to match the speed needed for your application.
  • Increases efficiencies of the fuels
  • Excellent absorbency
  • Stabilization makes removal of waste easier and more efficient

Sizes & Absorbencies

  • Customizable levels of superabsorbent polymer offer absorbencies of up to 1,005 g/sq. ft. in deionized water, increasing the amount of time between filter changes.
